Move git-rev-list --merge-order usage check for 'OpenSSL not linked' after
test 1; we cannot trigger this unless we try to actually use --merge-order

This patch converts a stat() to an lstat() call, thereby fixing the case
when the date of a symlink was not the same as the one recorded in the
index. The included test case demonstrates this.

This is for the case that the symlink points to a non-existing file. If
the file exists, worse things than just an error message happen.

dietlibc versions of malloc, calloc and realloc all return NULL if
they're told to allocate 0 bytes, causes the x* wrappers to die().

There are several more places where these calls could end up asking
for 0 bytes, too...

Maybe simply not die()-ing in the x* wrappers if 0/NULL is returned
when the requested size is zero is a safer and easier way to go.

This does three things:

 . It simplifies the logic to handle the case in which no
   refs are given on the command line, and fixes the bug
   when only "--heads" is specified.  Earlier we showed
   them twice.

 . It avoids to add the same ref twice.

 . It sorts the glob result (e.g. "git show-branch
   'tags/v1.0*'") according to a more version friendly
   sort order.

sha1_to_hex() returns a pointer to a static buffer. Some of its users
modify that buffer by appending a newline character. Other users rely
on the fact that you can call

Wnen refusing to push a head, we said cryptic "remote 'branch'
object X does not exist on local" or "remote ref 'branch' is not
a strict subset of local ref 'branch'".  That was gittish.

Since the most likely reason this happens is because the pushed
head was not up-to-date, clarify the error message to say that
straight, and suggest pulling first.

It used to make sense to have git-send-pack talk about the things it sent
when (a) it was a new program and (b) nobody had a lot of tags and
branches.

These days, it's just distracting to see tons of

	'refs/tags/xyz': up-to-date
	...

when updating a remote repo.

So shut it up by default, and add a "--verbose" flag for those who really
want to see it.

Also, since this makes he case of everything being up-to-date just totally
silent, make it say "Everything up-to-date" if no refs needed updating.

This fixes the longstanding "Racy GIT" problem, which was pretty
much there from the beginning of time, but was first
demonstrated by Pasky in this message on October 24, 2005:

    http://marc.theaimsgroup.com/?l=git&m=113014629716878

If you run the following sequence of commands:

	echo frotz >infocom
        git update-index --add infocom
        echo xyzzy >infocom

so that the second update to file "infocom" does not change
st_mtime, what is recorded as the stat information for the cache
entry "infocom" exactly matches what is on the filesystem
(owner, group, inum, mtime, ctime, mode, length).  After this
sequence, we incorrectly think "infocom" file still has string
"frotz" in it, and get really confused.  E.g. git-diff-files
would say there is no change, git-update-index --refresh would
not even look at the filesystem to correct the situation.

Some ways of working around this issue were already suggested by
Linus in the same thread on the same day, including waiting
until the next second before returning from update-index if a
cache entry written out has the current timestamp, but that
means we can make at most one commit per second, and given that
the e-mail patch workflow used by Linus needs to process at
least 5 commits per second, it is not an acceptable solution.
Linus notes that git-apply is primarily used to update the index
while processing e-mailed patches, which is true, and
git-apply's up-to-date check is fooled by the same problem but
luckily in the other direction, so it is not really a big issue,
but still it is disturbing.

The function ce_match_stat() is called to bypass the comparison
against filesystem data when the stat data recorded in the cache
entry matches what stat() returns from the filesystem.  This
patch tackles the problem by changing it to actually go to the
filesystem data for cache entries that have the same mtime as
the index file itself.  This works as long as the index file and
working tree files are on the filesystems that share the same
monotonic clock.  Files on network mounted filesystems sometimes
get skewed timestamps compared to "date" output, but as long as
working tree files' timestamps are skewed the same way as the
index file's, this approach still works.  The only problematic
files are the ones that have the same timestamp as the index
file's, because two file updates that sandwitch the index file
update must happen within the same second to trigger the
problem.
