9ac13ec941 atomic write for sideband remote messages
It has been a few times that I ended up with such a confusing display:

|remote: Generating pack...
|remote: Done counting 17 objects.
|remote: Result has 9 objects.
|remote: Deltifying 9 objects.
|remote:  100% (9/9) done
|remote: Unpacking 9 objects
|Total 9, written 9 (delta 8), reused 0 (delta 0)
| 100% (9/9) done

The confusion can be avoided in most cases by writing the remote message
in one go to prevent interleacing with local messages.  The buffer
declaration has been moved inside recv_sideband() to avoid extra string
copies.

d47f3db75c Prepare larger packet buffer for upload-pack protocol.
The original side-band support added to the upload-pack protocol used the
default 1000-byte packet length.  The pkt-line format allows up to 64k, so
prepare the receiver for the maximum size, and have the uploader and
downloader negotiate if larger packet length is allowed.

49a52b1d1f Move sideband client side support into reusable form.
This moves the receiver side of the sideband support from
fetch-clone.c to sideband.c and its header file, so that
archiver protocol can use it.

dfa4647812 fetch/clone: mark messages from remote side stand out.
When dealing with a corrupt or out of sync remote repository,
the user often gets error messages like this:

	error: refs/heads/devel does not point to a valid commit object!

which leaves the user wondering if the breakage is on the local
end or on the remote end.  This is unnecessarily alarming.

This patch changes the way we display messages received from the
remote side over the git protocol sideband (i.e. stderr stream
of the remote process).  It shows them with blue background with
white letters, but this presentation is subject to proposals of
better ways from the list.

The problem was pointed out by Andrew Morton.

82e5a82fd7 Fix more typos, primarily in the code
The only visible change is that git-blame doesn't understand
"--compability" anymore, but it does accept "--compatibility" instead,
which is already documented.

583b7ea31b upload-pack/fetch-pack: support side-band communication
This implements a protocol extension between fetch-pack and
upload-pack to allow stderr stream from upload-pack (primarily
used for the progress bar display) to be passed back.

98deeaa82f Fix fetch-clone in the presense of signals
We shouldn't fail a fetch just because a signal might have interrupted
the read.

Normally, we don't install any signal handlers, so EINTR really shouldn't
happen. That said, really old versions of Linux will interrupt an
interruptible system call even for signals that turn out to be ignored
(SIGWINCH is the classic example - resizing your xterm would cause it).
The same might well be true elsewhere too.

Also, since receive_keep_pack() doesn't control the caller, it can't know
that no signal handlers exist.

c548cf4ee0 Make "git clone" pack-fetching download statistics better
Average it out over a few events to make the numbers stable, and fix the
silly usec->binary-ms conversion.

Yeah, yeah, it's arguably eye-candy to keep the user calm, but let's do
that right.

5ee2ad654b Make "git clone" less of a deathly quiet experience
It used to be that "git-unpack-objects" would give nice percentages, but
now that we don't unpack the initial clone pack any more, it doesn't. And
I'd love to do that nice percentage view in the pack objects downloader
too, but the thing doesn't even read the pack header, much less know how
much it's going to get, so I was lazy and didn't.

Instead, it at least prints out how much data it's gotten, and what the
packing speed is. Which makes the user realize that it's actually doing
something useful instead of sitting there silently (and if the recipient
knows how large the final result is, he can at least make a guess about
when it migt be done).

So with this patch, I get something like this on my DSL line:

	[torvalds@g5 ~]$ time git clone master.kernel.org:/pub/scm/linux/kernel/git/torvalds/linux-2.6 clone-test
	Packing 188543 objects
	  48.398MB  (154 kB/s)

where even the speed approximation seems to be roughtly correct (even
though my algorithm is a truly stupid one, and only really gives "speed in
the last half second or so").

Anyway, _something_ like this is definitely needed. It could certainly be
better (if it showed the same kind of thing that git-unpack-objects did,
that would be much nicer, but would require parsing the object stream as
it comes in). But this is  big step forward, I think.

77cb17e940 Exec git programs without using PATH.
The git suite may not be in PATH (and thus programs such as
git-send-pack could not exec git-rev-list).  Thus there is a need for
logic that will locate these programs.  Modifying PATH is not
desirable as it result in behavior differing from the user's
intentions, as we may end up prepending "/usr/bin" to PATH.

- git C programs will use exec*_git_cmd() APIs to exec sub-commands.
- exec*_git_cmd() will execute a git program by searching for it in
  the following directories:
	1. --exec-path (as used by "git")
	2. The GIT_EXEC_PATH environment variable.
	3. $(gitexecdir) as set in Makefile (default value $(bindir)).
- git wrapper will modify PATH as before to enable shell scripts to
  invoke "git-foo" commands.

Ideally, shell scripts should use the git wrapper to become independent
of PATH, and then modifying PATH will not be necessary.

[jc: with minor updates after a brief review.]

ad89721508 fetch-pack: -k option to keep downloaded pack.
Split out the functions that deal with the socketpair after
finishing git protocol handshake to receive the packed data into
a separate file, and use it in fetch-pack to keep/explode the
received pack data.  We earlier had something like that on
clone-pack side once, but the list discussion resulted in the
decision that it makes sense to always keep the pack for
clone-pack, so unpacking option is not enabled on the clone-pack
side, but we later still could do so easily if we wanted to with
this change.
