Introduce commit.gpgsign configuration variable to force every
commit to be GPG signed. The variable cannot be overriden from the
command line of some of the commands that create commits except for

such a good idea.

This instance was left out when many match_pathspec() call sites that
take input from dir_entry were converted to dir_path_match() because
it passed a path with the trailing slash stripped out to match_pathspec()
while the others did not. Stripping for all call sites back then would
be a regression because match_pathspec() did not know how to match
pathspec foo/ against _directory_ foo (the stripped version of path
"foo/").
match_pathspec() knows how to do it now. And dir_path_match() strips
the trailing slash also. Use the new function, because the stripping
code is removed in the next patch.

This patch activates the DO_MATCH_DIRECTORY code in m_p_i(), which
makes "git diff HEAD submodule/" and "git diff HEAD submodule" produce
the same output. Previously only the version without trailing slash
returns the difference (if any).
That's the effect of new ce_path_match(). dir_path_match() is not
executed by the new tests. And it should not introduce regressions.
Previously if path "dir/" is passed in with pathspec "dir/", they
obviously match. With new dir_path_match(), the path becomes
_directory_ "dir" vs pathspec "dir/", which is not executed by the old
code path in m_p_i(). The new code path is executed and produces the
same result.
The other case is pathspec "dir" and path "dir/" is now turned to
"dir" (with DO_MATCH_DIRECTORY). Still the same result before or after
the patch.
So why change? Because of the next patch about clean.c.

A long time ago, for some reason I was not happy with
match_pathspec(). I created a better version, match_pathspec_depth()
that was suppose to replace match_pathspec()
eventually. match_pathspec() has finally been gone since 6 months
ago. Use the shorter name for match_pathspec_depth().

This helps reduce the number of match_pathspec_depth() call sites and
show how m_p_d() is used. And it usage is:
- match against an index entry (ce_path_match or match_pathspec_depth
in ls-files)
- match against a dir_entry from read_directory (dir_path_match and
match_pathspec_depth in clean.c, which will be converted later)
- resolve-undo (rerere.c and ls-files.c)

When --mixed is used, entries could be removed from index if the
target ref does not have them. When "reset" is used in preparation for
commit spliting (in a dirty worktree), it could be hard to track what
files to be added back. The new option --intent-to-add simplifies it
by marking all removed files intent-to-add.

When a repo was fully repacked, and is repacked again, we may run
into the situation that "new" packfiles have the same name as
already existing ones (traditionally packfiles have been named after
the list of names of objects in them, so repacking all the objects
in a single pack would have produced a packfile with the same name).
The logic is to rename the existing ones into filename like
"old-XXX", create the new ones and then remove the "old-" ones.
When something went wrong in the middle, this sequence is rolled
back by renaming the "old-" files back.
The renaming into "old-" did not work as intended, because
file_exists() was done on "XXX", not "pack-XXX". Also when rolling
back the change, the code tried to rename "old-pack-XXX" but the
saved ones are named "old-XXX", so this couldn't have worked.

In the original shell version of git-repack, any options
destined for pack-objects were left as strings, and passed
as a whole. Since the C rewrite in commit a1bbc6c (repack:
rewrite the shell script in C, 2013-09-15), we now parse
these values to integers internally, then reformat the
integers when passing the option to pack-objects.
This has the advantage that we catch format errors earlier
(i.e., when repack is invoked, rather than when pack-objects
is invoked).
It has three disadvantages, though:
1. Our internal data types may not be the right size. In
the case of "--window-memory" and "--max-pack-size",
these are "unsigned long" in pack-objects, but we can
only represent a regular "int".
2. Our parsing routines might not be the same as those of
pack-objects. For the two options above, pack-objects
understands "100m" to mean "100 megabytes", but repack
does not.
3. We have to keep a sentinel value to know whether it is
worth passing the option along. In the case of
"--window-memory", we currently do not pass it if the
value is "0". But that is a meaningful value to
pack-objects, where it overrides any configured value.
We can fix all of these by simply passing the strings from
the user along to pack-objects verbatim. This does not
actually fix anything for "--depth" or "--window", but these
are converted, too, for consistency.

The previous commit c57f628 (mv: let 'git mv file no-such-dir/' error out)
relies on that rename("file", "no-such-dir/") fails if the directory does not
exist (note the trailing slash). This does not work as expected on Windows:
This rename() call does not fail, but renames "file" to "no-such-dir" (not to
"no-such-dir/file"). Insert an explicit check for this case to force an error.
This changes the error message from
$ git mv file no-such-dir/
fatal: renaming 'file' failed: Not a directory
to
$ git mv file no-such-dir/
fatal: destination directory does not exist, source=file, destination=no-such-dir/
