This patch on top of 'next' makes built-in git-cherry handle root
commits.

It moves the static function log-tree.c::diff_root_tree() to
tree-diff.c and makes it more similar to diff_tree_sha1() by
shuffling around arguments and factoring out the call to
log_tree_diff_flush().  Consequently the name is changed to
diff_root_tree_sha1().  It is a version of diff_tree_sha1() that
compares the empty tree (= root tree) against a single 'real' tree.

This function is then used in get_patch_id() to compute patch IDs
for initial commits instead of SEGFAULTing, as the current code
does if confronted with parentless commits.

This replaces the shell script git-cherry with a version written in C.

The behaviour of the new version differs from the original in two
points: it has no long help any more, and it is handling the (optional)
third parameter a bit differently.  Basically, it does the equivalent
of

   ours=`git-rev-list $ours ^$limit ^$upstream`

instead of

   ours=`git-rev-list $ours ^$limit`

Aside of potential confusion in the body of git_search(), no other $/

In the older times, the clients did not say which host they were trying

This removes trailing blanks from git-generated diff headers
the same way a similar patch did that for GNU diff:

  http://article.gmane.org/gmane.comp.gnu.utils.bugs/13839

That is, it removes trailing blanks on the hunk header line that
shows the function name.

I noticed that a cron-launched "git-clone --quiet" was generating
progress output to standard error -- and thus always spamming me.
The offending output was due to git-clone invoking git-read-tree with
its undocumented -v option.
This change turns off "-v" for --quiet.

We already generate a Date: header based on when the patch was
emailed.  git-format-patch includes the Date: header of the
patch.  Having two Date: headers is just confusing, so we
just use the current Date:

Often the mailed patches in a patch series are created over a
series of several hours or days, so the Date: header from the
original commit is incorrect for email, and often far off enough
for spam filters to complain.

Tonight I found a git-cvsserver instance spending a lot of time in
disk IO while trying to process operations against a Git repository
with >30,000 objects contained in it.

Blowing away my SQLLite database and rebuilding all tables with
indexes on the attributes that git-cvsserver frequently runs queries
against seems to have resolved the issue quite nicely.

Since the indexes shouldn't hurt performance on small repositories
and always helps on larger repositories we should just always create
them when creating the revision storage tables.

This patch only adds the streaming capability to index-pack.  Although
the code is different it has the exact same functionality as before to
make sure nothing broke.

This is in preparation for receiving packs over the net, parse them on
the fly, fix them up if they are "thin" packs, and keep the resulting
pack instead of exploding it into loose objects.  But such functionality
should come separately.

One immediate advantage of this patch is that index-pack can now deal
with packs up to 4GB in size even on 32-bit architectures since the pack
is not entirely mmap()'d all at once anymore.
