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.

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.

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.

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.

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.

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.

The low-level attribute and gitignore code will try to look
in $GIT_DIR/info for any repo-level configuration files,
even if we have not actually determined that we are in a
repository (e.g., running "git grep --no-index"). In such a
case they end up looking for ".git/info/attributes", etc.
This is generally harmless, as such a file is unlikely to
exist outside of a repository, but it's still conceptually
the wrong thing to do.
Let's detect this situation explicitly and skip reading the
file (i.e., the same behavior we'd get if we were in a
repository and the file did not exist).

An empty string used as a pathspec element has always meant
'everything matches', but it is too easy to write a script that
finds a path to remove in $path and run 'git rm "$paht"', which
ends up removing everything. Start warning about this use of an
empty string used for 'everything matches' and ask users to use a
more explicit '.' for that instead.
The hope is that existing users will not mind this change, and
eventually the warning can be turned into a hard error, upgrading
the deprecation into removal of this (mis)feature.
