When we have a rename/rename(1to2) conflict, each of the renames can
collide with a file addition. Each of these rename/add conflicts suffered
from the same kinds of problems that normal rename/add suffered from.
Make the code use handle_file_conflicts() as well so that we get all the
same fixes and consistent behavior between the different conflict types.

This results in no-net change of behavior, it simply ensures that all
file-collision conflict handling types are being handled the same by
calling the same function.

This makes the rename/rename(2to1) conflicts use the new
handle_file_collision() function. Since that function was based
originally on the rename/rename(2to1) handling code, the main
differences here are in what was added. In particular:
* Instead of storing files at collide_path~HEAD and collide_path~MERGE,
the files are two-way merged and recorded at collide_path.
* Instead of recording the version of the renamed file that existed
on the renamed side in the index (thus ignoring any changes that
were made to the file on the side of history without the rename),
we do a three-way content merge on the renamed path, then store
that at either stage 2 or stage 3.
* Note that since the content merge for each rename may have conflicts,
and then we have to merge the two renamed files, we can end up with
nested conflict markers.

This makes the rename/add conflict handling make use of the new
handle_file_collision() function, which fixes several bugs and improves
things for the rename/add case significantly. Previously, rename/add
would:
* Not leave any higher order stage entries in the index, making it
appear as if there were no conflict.
* Would place the rename file at the colliding path, and move the
added file elsewhere, which combined with the lack of higher order
stage entries felt really odd. It's not clear to me why the
rename should take precedence over the add; if one should be moved
out of the way, they both probably should.
* In the recursive case, it would do a two way merge of the added
file and the version of the renamed file on the renamed side,
completely excluding modifications to the renamed file on the
unrenamed side of history.
Use the new handle_file_collision() to fix all of these issues.

There are three conflict types that represent two (possibly entirely
unrelated) files colliding at the same location:
* add/add
* rename/add
* rename/rename(2to1)
These three conflict types already share more similarity than might be
immediately apparent from their description: (1) the handling of the
rename variants already involves removing any entries from the index
corresponding to the original file names[*], thus only leaving entries
in the index for the colliding path; (2) likewise, any trace of the
original file name in the working tree is also removed. So, in all
three cases we're left with how to represent two colliding files in both
the index and the working copy.
[*] Technically, this isn't quite true because rename/rename(2to1)
conflicts in the recursive (o->call_depth > 0) case do an "unrename"
since about seven years ago. But even in that case, Junio felt
compelled to explain that my decision to "unrename" wasn't necessarily
the only or right answer -- search for "Comment from Junio" in t6036 for
details.
My initial motivation for looking at these three conflict types was that
if the handling of these three conflict types is the same, at least in
the limited set of cases where a renamed file is unmodified on the side
of history where the file is not renamed, then a significant performance
improvement for rename detection during merges is possible. However,
while that served as motivation to look at these three types of
conflicts, the actual goal of this new function is to try to improve the
handling for all three cases, not to merely make them the same as each
other in that special circumstance.
=== Handling the working tree ===
The previous behavior for these conflict types in regards to the
working tree (assuming the file collision occurs at 'foo') was:
* add/add does a two-way merge of the two files and records it as 'foo'.
* rename/rename(2to1) records the two different files into two new
uniquely named files (foo~HEAD and foo~$MERGE), while removing 'foo'
from the working tree.
* rename/add records the two different files into two different
locations, recording the add at foo~$SIDE and, oddly, recording
the rename at foo (why is the rename more important than the add?)
So, the question for what to write to the working tree boils down to
whether the two colliding files should be two-way merged and recorded in
place, or recorded into separate files. As per discussion on the git
mailing lit, two-way merging was deemed to always be preferred, as that
makes these cases all more like content conflicts that users can handle
from within their favorite editor, IDE, or merge tool. Note that since
renames already involve a content merge, rename/add and
rename/rename(2to1) conflicts could result in nested conflict markers.
=== Handling of the index ===
For a typical rename, unpack_trees() would set up the index in the
following fashion:
old_path new_path
stage1: 5ca1ab1e 00000000
stage2: f005ba11 00000000
stage3: 00000000 b0a710ad
And merge-recursive would rewrite this to
new_path
stage1: 5ca1ab1e
stage2: f005ba11
stage3: b0a710ad
Removing old_path from the index means the user won't have to `git rm
old_path` manually every time a renamed path has a content conflict.
It also means they can use `git checkout [--ours|--theirs|--conflict|-m]
new_path`, `git diff [--ours|--theirs]` and various other commands that
would be difficult otherwise.
This strategy becomes a problem when we have a rename/add or
rename/rename(2to1) conflict, however, because then we have only three
slots to store blob sha1s and we need either four or six. Previously,
this was handled by continuing to delete old_path from the index, and
just outright ignoring any blob shas from old_path. That had the
downside of deleting any trace of changes made to old_path on the other
side of history. This function instead does a three-way content merge of
the renamed file, and stores the blob sha1 for that at either stage2 or
stage3 for new_path (depending on which side the rename came from). That
has the advantage of bringing information about changes on both sides and
still allows for easy resolution (no need to git rm old_path, etc.), but
does have the downside that if the content merge had conflict markers,
then what we store in the index is the sha1 of a blob with conflict
markers. While that is a downside, it seems less problematic than the
downsides of any obvious alternatives, and certainly makes more sense
than the previous handling. Further, it has a precedent in that when we
do recursive merges, we may accept a file with conflict markers as the
resolution for the merge of the merge-bases, which will then show up in
the index of the outer merge at stage 1 if a conflict exists at the outer
level.

Later patches in this series will modify file collision conflict
handling (e.g. from rename/add and rename/rename(2to1) conflicts) so
that multiply nested conflict markers can arise even before considering
conflicts in the virtual merge base. Including the virtual merge base
will provide a way to get triply (or higher) nested conflict markers.
This new way to get nested conflict markers will force the need for a
more general mechanism to extend the length of conflict markers in order
to differentiate between different nestings.
Along with this change to conflict marker length handling, we want to
make sure that we don't regress handling for other types of conflicts
with nested conflict markers. Add a more involved testcase using
merge.conflictstyle=diff3, where not only does the virtual merge base
contain conflicts, but its virtual merge base does as well (i.e. a case
with triply nested conflict markers). While there are multiple
reasonable ways to handle nested conflict markers in the virtual merge
base for this type of situation, the easiest approach that dovetails
well with the new needs for the file collision conflict handling is to
require that the length of the conflict markers increase with each
subsequent nesting.
Subsequent patches which change the rename/add and rename/rename(2to1)
conflict handling will modify the extra_marker_size flag appropriately
for their new needs.

When a single file is renamed, it can also be modified, yielding the
possibility of that renamed file having content conflicts. If two
different such files are renamed into the same location, then two-way
merging those files may result in nested conflicts. Add a testcase that
makes sure we get this case correct, and uses different lengths of
conflict markers to differentiate between the different nestings.
Also add another case with an extra (i.e. third) level of conflict
markers due to using merge.conflictstyle=diff3 and the virtual merge
base also having conflicts present.

Add testcases dealing with file collisions for the following types of
conflicts:
* add/add
* rename/add
* rename/rename(2to1)
All these conflict types simplify down to two files "colliding"
and should thus be handled similarly. This means that rename/add and
rename/rename(2to1) conflicts need to be modified to behave the same as
add/add conflicts currently do: the colliding files should be two-way
merged (instead of the current behavior of writing the two colliding
files out to separate temporary unique pathnames). Add testcases which
check this; subsequent commits will fix the conflict handling to make
these tests pass.

We want to load unmerged entries from HEAD into the index at stage 2 and
from MERGE_HEAD into stage 3. Similarly, folks expect merge conflicts
to look like
<<<<<<<< HEAD
content from our side
========
content from their side
>>>>>>>> MERGE_HEAD
not
<<<<<<<< MERGE_HEAD
content from their side
========
content from our side
>>>>>>>> HEAD
The correct order usually comes naturally and for free, but with renames
we often have data in the form {rename_branch, other_branch}, and
working relative to the rename first (e.g. for rename/add) is more
convenient elsewhere in the code. Address the slight impedance
mismatch by having some functions re-call themselves with flipped
arguments when the branch order is reversed.
Note that setup_rename_conflict_info() has one asymmetry in it, in
setting dst_entry1->processed=0 but not doing similarly for
dst_entry2->processed. When dealing with rename/rename and similar
conflicts, we do not want the processing to happen twice, so the
desire to only set one of the entries to unprocessed is intentional.
So, while this change modifies which branch's entry will be marked as
unprocessed, that dovetails nicely with putting HEAD first so that we
get the index stage entries and conflict markers in the right order.

Each individual file involved in a rename could have also been modified
on both sides of history, meaning it may need to have content merges.
If two such files are renamed into the same location, then on top of the
two natural auto-merging messages we also have to two-way merge the
result, giving us messages that look like
Auto-merging somefile.c (was somecase.c)
Auto-merging somefile.c (was somefolder.c)
Auto-merging somefile.c
However, despite the fact that I was the one who put the "(was %s)"
portions into the messages (and just a few months ago), I was still
initially confused when running into a rename/rename(2to1) case and
wondered if somefile.c had been merged three times. Update this to
instead be:
Auto-merging version of somefile.c from somecase.c
Auto-merging version of somefile.c from someportfolio.c
Auto-merging somefile.c
This is an admittedly long set of messages for a single path, but you
only get all three messages when dealing with the rare case of a
rename/rename(2to1) conflict where both sides of both original files
were also modified, in conflicting ways.

Summary:
merge_file_1() -> merge_mode_and_contents()
merge_content() -> handle_content_merge()
merge_file_1() is a very unhelpful name. Rename it to
merge_mode_and_contents() to reflect what it does.
merge_content() calls merge_mode_and_contents() to do the main part of
its work, but most of this function was about higher level stuff, e.g.
printing out conflict messages, updating skip_worktree bits, checking
for ability to avoid updating the working tree or for D/F conflicts
being in the way, etc. Since there are several handle_*() functions for
similar levels of checking and handling in merge-recursive.c (e.g.
handle_change_delete(), handle_rename_rename_2to1()), let's rename this
function to handle_content_merge().

The function names merge_file_one() and merge_file_1() aren't
particularly intuitive function names, especially since there is no
associated merge_file() function that these are related to. The
previous commit showed that merge_file_one() was prone to be called when
merge_file_1() should be, and since it is just a thin wrapper around
merge_file_1() anyway and only has one caller left, let's just remove
merge_file_one() entirely.
(It also turns out that the one remaining caller of merge_file_one()
has very broken code that needs to be completely rewritten, but that's
the subject of a future patch series; for now, we're just translating
it into a merge_file_1() call.)

merge_file_one() is a convenience function taking a bunch of oids and
modes, combining each pair into a diff_filespec, and then calling
merge_file_1(). When we already start with diff_filespec's, we can
just call merge_file_1() directly instead of splitting out the oids
and modes for the wrapper to recombine into what we already had.

merge_3way() has code to mark different sides of the conflict with info
about where the content comes from. If the names of the files involved
match, it simply uses the branch name. If the names of the files do not
match, it uses branchname:filename. Unfortunately, merge_content()
previously always called it with one.path = a.path = b.path. Granted,
it didn't have other path information available to it for years, but
that was corrected by passing rename_conflict_info in commit
3c217c077a86 ("merge-recursive: Provide more info in conflict markers
with file renames", 2011-08-11). In that commit, instead of just fixing
the bug with the pathnames, it created fake branch names incorporating
both the branch name and file name.
This "fake branch" workaround was extended further when I pulled that
logic out into a special function in commit dac4741554e7
("merge-recursive: Create function for merging with branchname:file
markers", 2011-08-11), and a number of other sites outside of
merge_content() have been added which call into that. However, this
Rube-Goldberg-esque setup is not merely duplicate code and unnecessary
work, it also risked having other callsites invoke it in a way that
would result in markers of the form branchname:filename:filename (i.e.
with the filename repeated).
Fix this whole mess by:
- setting one.path, a.path, and b.path appropriately
- calling merge_file_1() directly
- deleting the merge_file_special_markers() workaround wrapper

"git rev-list --stdin </dev/null" used to be an error; it now shows
no output without an error. "git rev-list --stdin --default HEAD"
still falls back to the given default when nothing is given on the
standard input.

"git checkout -b newbranch [HEAD]" should not have to do as much as
checking out a commit different from HEAD. An attempt is made to
optimize this special case.

Running "git clone" against a project that contain two files with
pathnames that differ only in cases on a case insensitive
filesystem would result in one of the files lost because the
underlying filesystem is incapable of holding both at the same
time. An attempt is made to detect such a case and warn.

clean""
This reverts commit 6f924265a0bf6efa677e9a684cebdde958e5ba06, which
started to require that we have an executable git available in order
to say "make clean", which gives us a chicken-and-egg problem.
Having to have Git installed, or be in a repository, in order to be
able to run an optional "doc-diff" tool is fine. Requiring either
in order to run "make clean" is a different story.

This is a test of smart HTTP, so it should use the smart HTTP endpoints
(e.g. /info/refs?service=git-receive-pack), not dumb HTTP (HEAD).
