Improve the output we emit on --validate error to:
* Say "FILE:LINE" instead of "FILE: LINE", to match "grep -n",
compiler error messages etc.
* Don't say "patch contains a" after just mentioning the filename,
just leave it at "FILE:LINE: is longer than[...]. The "contains a"
sounded like we were talking about the file in general, when we're
actually checking it line-by-line.
* Don't just say "rejected by sendemail-validate hook", but combine
that with the system_or_msg() output to say what exit code the hook
died with.
I had an aborted attempt to make the line length checker note all
lines that were longer than the limit. I didn't think that was worth
the effort, but I've left in the testing change to check that we die
as soon as we spot the first long line.

When multiple packs in the multi-pack index contain the same object, the
MIDX machinery must make a choice about which pack it associates with
that object. Prior to this patch, the lowest-ordered[1] pack was always
selected.
Pack selection for duplicate objects is relatively unimportant today,
but it will become important for multi-pack bitmaps. This is because we
can only invoke the pack-reuse mechanism when all of the bits for reused
objects come from the reuse pack (in order to ensure that all reused
deltas can find their base objects in the same pack).
To encourage the pack selection process to prefer one pack over another
(the pack to be preferred is the one a caller would like to later use as
a reuse pack), introduce the concept of a "preferred pack". When
provided, the MIDX code will always prefer an object found in a
preferred pack over any other.
No format changes are required to store the preferred pack, since it
will be able to be inferred with a corresponding MIDX bitmap, by looking
up the pack associated with the object in the first bit position (this
ordering is described in detail in a subsequent commit).
[1]: the ordering is specified by MIDX internals; for our purposes we
can consider the "lowest ordered" pack to be "the one with the
most-recent mtime.

In some scenarios, users may want more history than the repository
offered for cloning, which happens to be a shallow repository, can
give them. But because users don't know it is a shallow repository
until they download it to local, we may want to refuse to clone
this kind of repository, without creating any unnecessary files.
The '--depth=x' option cannot be used as a solution; the source may
be deep enough to give us 'x' commits when cloned, but the user may
later need to deepen the history to arbitrary depth.
Teach '--reject-shallow' option to "git clone" to abort as soon as
we find out that we are cloning from a shallow repository.

After we run parse_object_buffer() to get an object's contents, we try
to check that the return value wasn't NULL. However, since our "struct
object" is a pointer-to-pointer, and we assign like:
*obj = parse_object_buffer(...);
it's not correct to check:
if (!obj)
That will always be true, since our double pointer will continue to
point to the single pointer (which is itself NULL). This is a regression
that was introduced by aa46a0da30 (ref-filter: use oid_object_info() to
get object, 2018-07-17); since that commit we'll segfault on a parse
failure, as we try to look at the NULL object pointer.
There are many ways a parse could fail, but most of them are hard to set
up in the tests (it's easy to make a bogus object, but update-ref will
refuse to point to it). The test here uses a tag which points to a wrong
object type. A parse of just the broken tag object will succeed, but
seeing both tag objects in the same process will lead to a parse error
(since we'll see the pointed-to object as both types).

When writing a new pack with a bitmap, it is sometimes convenient to
indicate some reference prefixes which should receive priority when
selecting which commits to receive bitmaps.
A truly motivated caller could accomplish this by setting
'pack.islandCore', (since all commits in the core island are similarly
marked as preferred) but this requires callers to opt into using delta
islands, which they may or may not want to do.
Introduce a new multi-valued configuration, 'pack.preferBitmapTips' to
allow callers to specify a list of reference prefixes. All references
which have a prefix contained in 'pack.preferBitmapTips' will mark their
tips as "preferred" in the same way as commits are marked as preferred
for selection by 'pack.islandCore'.
The choice of the verb "prefer" is intentional: marking the NEEDS_BITMAP
flag on an object does *not* guarantee that that object will receive a
bitmap. It merely guarantees that that commit will receive a bitmap over
any *other* commit in the same window by bitmap_writer_select_commits().
The test this patch adds reflects this quirk, too. It only tests that
a commit (which didn't receive bitmaps by default) is selected for
bitmaps after changing the value of 'pack.preferBitmapTips' to include
it. Other commits may lose their bitmaps as a byproduct of how the
selection process works (bitmap_writer_select_commits() ignores the
remainder of a window after seeing a commit with the NEEDS_BITMAP flag).
This configuration will aide in selecting important references for
multi-pack bitmaps, since they do not respect the same pack.islandCore
configuration. (They could, but doing so may be confusing, since it is
packs--not bitmaps--which are influenced by the delta-islands
configuration).
In a fork network repository (one which lists all forks of a given
repository as remotes), for example, it is useful to set
pack.preferBitmapTips to 'refs/remotes/<root>/heads' and
'refs/remotes/<root>/tags', where '<root>' is an opaque identifier
referring to the repository which is at the base of the fork chain.

Add a new 'bitmap' test-tool which can be used to list the commits that
have received bitmaps.
In theory, a determined tester could run 'git rev-list --test-bitmap
<commit>' to check if '<commit>' received a bitmap or not, since
'--test-bitmap' exits with a non-zero code when it can't find the
requested commit.
But this is a dubious behavior to rely on, since arguably 'git
rev-list' could continue its object walk outside of which commits are
covered by bitmaps.
This will be used to test the behavior of 'pack.preferBitmapTips', which
will be added in the following patch.

save_opts() should save any non-default values. It was intended to do
this, but since most options in struct replay_opts default to 0, it only
saved non-zero values. Unfortunately, this does not always work for
options.edit. Roughly speaking, options.edit had a default value of 0
for cherry-pick but a default value of 1 for revert. Make save_opts()
record a value whenever it differs from the default.
options.edit was also overly simplistic; we had more than two cases.
The behavior that previously existed was as follows:
Non-conflict commits Right after Conflict
revert Edit iff isatty(0) Edit (ignore isatty(0))
cherry-pick No edit See above
Specify --edit Edit (ignore isatty(0)) See above
Specify --no-edit (*) See above
(*) Before stopping for conflicts, No edit is the behavior. After
stopping for conflicts, the --no-edit flag is not saved so see
the first two rows.
However, the expected behavior is:
Non-conflict commits Right after Conflict
revert Edit iff isatty(0) Edit iff isatty(0)
cherry-pick No edit Edit iff isatty(0)
Specify --edit Edit (ignore isatty(0)) Edit (ignore isatty(0))
Specify --no-edit No edit No edit
In order to get the expected behavior, we need to change options.edit
to a tri-state: unspecified, false, or true. When specified, we follow
what it says. When unspecified, we need to check whether the current
commit being created is resolving a conflict as well as consulting
options.action and isatty(0). While at it, add a should_edit() utility
function that compresses options.edit down to a boolean based on the
additional information for the non-conflict case.
continue_single_pick() is the function responsible for resuming after
conflict cases, regardless of whether there is one commit being picked
or many. Make this function stop assuming edit behavior in all cases,
so that it can correctly handle !isatty(0) and specific requests to not
edit the commit message.

The 'read-midx' helper is used in places like t5319 to display basic

Remove the rebase.useBuiltin setting and the now-obsolete
GIT_TEST_REBASE_USE_BUILTIN test flag.
This was left in place after my d03ebd411c6 (rebase: remove the
rebase.useBuiltin setting, 2019-03-18) to help anyone who'd used the
experimental flag and wanted to know that it was the default, or that
they should transition their test environment to use the builtin
rebase unconditionally.
It's been more than long enough for those users to get a headsup about
this. So remove all the scaffolding that was left inplace after
d03ebd411c6. I'm also removing the documentation entry, if anyone
still has this left in their configuration they can do some source
archaeology to figure out what it used to do, which makes more sense
than exposing every git user reading the documentation to this legacy

The `-v<n>` option of `format-patch` can give nothing but an
integral iteration number to patches in a series. Some people,
however, prefer to mark a new iteration with only a small fixup
with a non integral iteration number (e.g. an "oops, that was
wrong" fix-up patch for v4 iteration may be labeled as "v4.1").
Allow `format-patch` to take such a non-integral iteration
number.
`<n>` can be any string, such as '3.1' or '4rev2'. In the case
where it is a non-integral value, the "Range-diff" and "Interdiff"
headers will not include the previous version.

When "git diff --no-index X Y" is run the modes of the files being
differ are normalized by canon_mode() in fill_filespec().
I recently broke that behavior in a patch of mine[1] which would pass
all tests, or not, depending on the umask of the git.git checkout.
Let's test for this explicitly. Arguably this should not be the
behavior of "git diff --no-index". We aren't diffing our own objects
or the index, so it might be useful to show mode differences between
files.
On the other hand diff(1) does not do that, and it would be needlessly
distracting when e.g. diffing an extracted tar archive whose contents
is the same, but whose file modes are different.
