ls-tree: chomp leading directories when run from a subdirectory

When run from a subdirectory, even though we filtered the output
based on where we were using pathspec, we wrote out the
repository relative paths, not subtree relative paths.  This
changes things so that it shows only the current subdirectory
relative paths.

For example, in Documentation subdirectory of git itself, this
used to be the case:

    $ git-ls-tree --name-only HEAD | grep how
    Documentation/git-show-branch.txt
    Documentation/git-show-index.txt
    Documentation/howto-index.sh
    Documentation/howto

But now it does this instead:

    $ git-ls-tree --name-only HEAD | grep how
    git-show-branch.txt
    git-show-index.txt
    howto-index.sh
    howto

There are two things to keep in mind.

1. This shows nothing.

   $ git-ls-tree --name-only HEAD ../ppc/

   This is to make things consistent with ls-files, which
   refuses relative path that goes uplevel.

2. These show things in full repository relative paths.  In this
   case, paths outside the current subdirectory are also shown.

   $ git-ls-tree --name-only --full-name HEAD | grep how
   Documentation/git-show-branch.txt
   Documentation/git-show-index.txt
   Documentation/howto-index.sh
   Documentation/howto

   $ git-ls-tree --name-only --full-name HEAD ../ppc/
   ppc/sha1.c
   ppc/sha1.h
   ppc/sha1ppc.S

The flag --full-name gives the same behaviour as 1.0, so it
ought to be the default if we really care about the backward
compatibility, but in practice no Porcelain runs ls-tree from a
subdirectory yet, and without --full-name is more human
friendly, so hopefully the default being not --full-name would
be acceptable.

Racy GIT

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.

refs to the standard output instead of making a clone of the
remote repository when explicit <head> parameters are given; the
