The platform specific tweaking part was using 'uname -o' which
is not always available.  Squelch error message from it.

It was suggested to chain the if..else, but I chose not to, because
maintaining the nested if..else if..else..endif endif to match is a
pain.  If we had "elif", things would have been different, though.
While we are at it, try not to invoke 'uname -s' for each platform
candidate.

This makes it possible to have a "sparse" git object subdirectory
structure, something that has become much more attractive now that people
use pack-files all the time.

As a result of pack-files, a git object directory doesn't necessarily have
any individual objects lying around, and in that case it's just wasting
space to keep the empty first-level object directories around: on many
filesystems the 256 empty directories will be aboue 1MB of diskspace.

Even more importantly, after you re-pack a project that _used_ to be
unpacked, you could be left with huge directories that no longer contain
anything, but that waste space and take time to look through.

With this change, "git prune-packed" can just do an rmdir() on the
directories, and they'll get removed if empty, and re-created on demand.

This patch also tries to fix up "write_sha1_from_fd()" to use the new
common infrastructure for creating the object files, closing a hole where
we might otherwise leave half-written objects in the object database.

[jc: I unoptimized the part that really removes the fan-out directories
 to ease transition.  init-db still wastes 1MB of diskspace to hold 256
 empty fan-outs, and prune-packed rmdir()'s the grown but empty directories,
 but runs mkdir() immediately after that -- reducing the saving from 150KB
 to 146KB.  These parts will be re-introduced when everybody has the
 on-demand capability.]

This adds more cruft to diff --git header to record the blob SHA1 and
the mode the patch/diff is intended to be applied against, to help the
receiving end fall back on a three-way merge.  The new header looks
like this:

    diff --git a/apply.c b/apply.c
    index 7be5041..8366082 100644
    --- a/apply.c
    +++ b/apply.c

    ...

Upon receiving such a patch, if the patch did not apply cleanly to the
target tree, the recipient can try to find the matching old objects in
her object database and create a temporary tree, apply the patch to
that temporary tree, and attempt a 3-way merge between the patched
temporary tree and the target tree using the original temporary tree
as the common ancestor.

The patch lifts the code to compute the hash for an on-filesystem
object from update-index.c and makes it available to the diff output
routine.

When you are applying 200 mails in sequence, .dotest/ directory
will be littered with many messsages, and when the patch in one
of them fails to apply, it is not obvious which message was
being processed.  Remove the one that has been already dealt
with, so that the last failed one is found typically as the
lowest numbered split message.

After git-apply fails, attempt to find a base tree that the patch
cleanly applies to, and do a three-way merge using that base tree into
the current index, if .dotest/.3way file exists.  This flag can be
controlled by giving -m flag to git-applymbox command.

When the fall-back merge fails, the working tree can be resolved the
same way as you would normally hand resolve a conflicting merge.
When making commit, use .dotest/final-commit as the log message
template.  Or you could just choose to 'git-checkout-index -f -a'
to revert the failed merge.

The current "git tag -s" thing always uses the tagger name as the signing
user key, which is very irritating, since my key is under my email
address, but the tagger key obviously contains the actual machine name
too.

Now, I could just use "GIT_COMMITTER_EMAIL" and force it to be my real
email, but I actually think that it's nice to see which machine I use for
my work.

So rather than force my tagger ID to have to match the gpg key name, just
support the "-u" flag to "git tag" instead. It implicitly enables signing,
since it doesn't make any sense without it. Thus:

	git tag -u <gpg-key-name> <tag-name> [<tagged-object>]

will use the named gpg key for signing.

Cloning from a repository with more than 256 refs (heads and tags
included) will choke, because upload-pack has a built-in limit of
feeding not more than MAX_NEEDS (currently 256) heads to underlying
git-rev-list.  This is a problem when cloning a repository with many
tags, like http://www.linux-mips.org/pub/scm/linux.git, which has 290+
tags.

This commit introduces a new flag, --all, to git-rev-list, to include
all refs in the repository.  Updated upload-pack detects requests that
ask more than MAX_NEEDS refs, and sends everything back instead.

We may probably want to tweak the definitions of MAX_NEEDS and
MAX_HAS, but that is a separate topic.
