"git merge-tree" used to mishandle "both sides added" conflict with
its own "create a fake ancestor file that has the common parts of

The "name_path" API was an attempt to reduce the need to construct
the full path out of a series of path components while walking a

is already flat. The API has been removed and its users have been

git-svn has not supported GIT_SVN_NO_OPTIMIZE_COMMITS for

There are no more callers that use this mode, and none
likely to be added (as our xdl_merge() eliminates the common
use of it for generating 3-way merge bases).
This is effectively a revert of a9ed376 (xdiff: generate
"anti-diffs" aka what is common to two files, 2006-06-28),
though of course trying to revert that ancient commit
directly produces many textual conflicts.

When merge_blobs sees an add/add conflict, it tries to
create a virtual base object for the 3-way merge that
consists of the common lines of each file. It inherited this
strategy from merge-one-file in 0c79938 (Improved three-way
blob merging code, 2006-06-28), and the point is to minimize
the size of the conflict hunks. That commit talks about "if
libxdiff were to ever grow a compatible three-way merge, it
could probably be directly plugged in".
That has long since happened. So as with merge-one-file in
the previous commit, this extra step is no longer necessary.
Our 3-way merge code is smart enough to do the minimizing
itself if we simply feed it an empty base, which is what the
more modern merge-recursive strategy already does.
Not only does this let us drop some code, but it removes an
overflow bug in generate_common_file(). We allocate a buffer
as large as the smallest of the two blobs, under the
assumption that there cannot be more common content than
what is in the smaller blob. However, xdiff may feed us
more: if neither file ends in a newline, it feeds us the
"\nNo newline at end of file" marker as common content, and
we write it into the output. If the differences between the
files are small than that string, we overflow the output
buffer. This patch solves it by simply dropping the buggy
code entirely.

When we see an add/add conflict on a file, we generate the
conflicted content by doing a 3-way merge with a "virtual"
base consisting of the common lines of the two sides. This
strategy dates back to cb93c19 (merge-one-file: use common
as base, instead of emptiness., 2005-11-09).
Back then, the next step was to call rcs merge to generate
the 3-way conflicts. Using the virtual base produced much
better results, as rcs merge does not attempt to minimize
the hunks. As a result, you'd get a conflict with the
entirety of the files on either side.
Since then, though, we've switched to using git-merge-file,
which uses xdiff's "zealous" merge. This will find the
minimal hunks even with just the simple, empty base.
Let's switch to using that empty base. It's simpler, more
efficient, and reduces our dependencies (we no longer need a
working diff binary). It's also how the merge-recursive
strategy handles this same case.
We can almost get rid of git-sh-setup's create_virtual_base,
but we don't here, for two reasons:
1. The functions in git-sh-setup are part of our public
interface, so it's possible somebody is depending on
it. We'd at least need to deprecate it first.
2. It's also used by mergetool's p4merge driver. It's
unknown whether its 3-way merge is as capable as git's;
if not, then it is benefiting from the function.

The memory allocation scheme for the textconv interface is a
bit tricky, and not well documented. It was originally
designed as an internal part of diff.c (matching
fill_mmfile), but gradually was made public.
Refactoring it is difficult, but we can at least improve the
situation by documenting the intended flow and enforcing it
with an in-code assertion.

The conversion from "svn.pathnameencoding" to UTF-8 should be applied
first, and then URL encoding should be applied on the resulting UTF-8
path. The reversed order of these transforms (used before this fix)
makes non-UTF-8 URL which causes error from Subversion such as
"Filesystem has no item: '...' path not found" when sending a rename (or
a copy) from non-ASCII path.

Without the initialization of $self->{pathnameencoding}, conversion in
repo_path() is always skipped as $self->{pathnameencoding} is undefined
even if "svn.pathnameencoding" is configured.
The lack of conversion results in mysterious failure of dcommit (e.g.
"Malformed XML") which happen only when a commit involves a change on
non-ASCII path.
