de9f7fa3b0 commit: simplify building parents list
Push pptr down into the FROM_MERGE branch of the if/else statement,
where it's actually used, and call commit_list_append() for appending
elements instead of playing tricks with commit_list_insert().  Call
copy_commit_list() in the amend branch instead of open-coding it.  Don't
bother setting pptr in the final branch as it's not used thereafter.

6d834ac8f1 doc: fix missing "::" in config list
The rebase.instructionFormat option is missing its "::" to
tell AsciiDoc that it's a list entry. As a result, the
option name gets lumped into the description in one big

28fab7b23d valgrind: support test helpers
Tests run with --valgrind call git commands through a wrapper script
that invokes valgrind on them.  This script (valgrind.sh) is in turn
invoked through symlinks created for each command in t/valgrind/bin/.

Since e6e7530d (test helpers: move test-* to t/helper/ subdirectory)
these symlinks have been broken for test helpers -- they point to the
old locations in the root of the build directory.  Fix that by teaching
the code for creating the links about the new location of the binaries,
and do the same in the wrapper script to allow it to find its payload.

a2c761ce5b git-svn: do not reuse caches memoized for a different architecture
Reusing cached data speeds up git-svn by quite a fair bit. However, if
the YAML module is unavailable, the caches are written to disk in an
architecture-dependent manner. That leads to problems when upgrading,
say, from 32-bit to 64-bit Git for Windows.

Let's just try to read those caches back if we detect the absence of the
YAML module and the presence of the file, and delete the file if it
could not be read back correctly.

Note that the only way to catch the error when the memoized cache could
not be read back is to put the call inside an `eval { ... }` block
because it would die otherwise; the `eval` block should also return `1`
in case of success explicitly since the function reading back the cached
data does not return an appropriate value to test for success.

This fixes https://github.com/git-for-windows/git/issues/233.

5c238e29a8 git-compat-util: move content inside ifdef/endif guards
Commit 3f2e2297b9 (add an extra level of indirection to
main(), 2016-07-01) added a declaration to git-compat-util.h,
but it was accidentally placed after the final #endif that
guards against multiple inclusions.

This doesn't have any actual impact on the code, since it's
not incorrect to repeat a function declaration in C. But
it's a bad habit, and makes it more likely for somebody else
to make the same mistake. It also defeats gcc's optimization
to avoid opening header files whose contents are completely
guarded.

4f03666ac6 diff: handle sha1 abbreviations outside of repository
When generating diffs outside a repository (e.g., with "diff
--no-index"), we may write abbreviated sha1s as part of
"--raw" output or the "index" lines of "--patch" output.
Since we have no object database, we never find any
collisions, and these sha1s get whatever static abbreviation
length is configured (typically 7).

However, we do blindly look in ".git/objects" to see if any
objects exist, even though we know we are not in a
repository. This is usually harmless because such a
directory is unlikely to exist, but could be wrong in rare
circumstances.

Let's instead notice when we are not in a repository and
behave as if the object database is empty (i.e., just use
the default abbrev length). It would perhaps make sense to
be conservative and show full sha1s in that case, but
showing the default abbreviation is what we've always done
(and is certainly less ugly).

Note that this does mean that:

  cd /not/a/repo
  GIT_OBJECT_DIRECTORY=/some/real/objdir git diff --no-index ...

used to look for collisions in /some/real/objdir but now
does not. This could be considered either a bugfix (we do
not look at objects if we have no repository) or a
regression, but it seems unlikely that anybody would care
much either way.

d6cece51b8 diff_aligned_abbrev: use "struct oid"
Since we're modifying this function anyway, it's a good time
to update it to the more modern "struct oid". We can also
drop some of the magic numbers in favor of GIT_SHA1_HEXSZ,
along with some descriptive comments.

d5e3b01e5b diff_unique_abbrev: rename to diff_aligned_abbrev
The word "align" describes how the function actually differs
from find_unique_abbrev, and will make it less confusing
when we add more diff-specific abbrevation functions that do
not do this alignment.

Since this is a globally available function, let's also move
its descriptive comment to the header file, where we
typically document function interfaces.

ef2ed5013c find_unique_abbrev: use 4-buffer ring
Some code paths want to format multiple abbreviated sha1s in
the same output line. Because we use a single static buffer
for our return value, they have to either break their output
into several calls or allocate their own arrays and use
find_unique_abbrev_r().

Intead, let's mimic sha1_to_hex() and use a ring of several
buffers, so that the return value stays valid through
multiple calls. This shortens some of the callers, and makes
it harder to for them to make a silly mistake.
