This was triggered by a query by Sam Ravnborg, and extends "git reset" to
reset the index and the .git/HEAD pointer to an arbitrarily named point.
For example
git reset HEAD^
will just reset the current HEAD to its own parent - leaving the working
directory untouched, but effectively un-doing the top-most commit. You
might want to do this if you realize after you committed that you made a
mistake that you want to fix up: reset your HEAD back to its previous
state, fix up the working directory and re-do the commit.
If you want to totally un-do the commit (and reset your working directory
to that point too), you'd first use "git reset HEAD^" to reset to the
parent, and then do a "git checkout -f" to reset the working directory
state to that point in time too.

This is my first attempt to adjust Debian and RPM to pass
prefix, to prepare the 0.99.4 release.
It updates debian/rules and git-core.spec.in to properly pass
prefix when building binary packages. It also updates
debian/changelog to make the resulting binary package name
0.99.4; this is not needed on the RPM side (it takes the version
number from the main Makefile).

Per discussion with people interested in binary packaging,
change the default template location from /etc/git-core to
/usr/share/git-core hierarchy. If a user wants to run git
before installing for whatever reason, in addition to adding
$src to the PATH environment variable, git-init-db can be run
with --template=$src/templates/blt/ parameter.

This extends the source side semantics to match what Linus
suggested.
An example:
$ git-send-pack kernel.org:/pub/scm/git/git.git pu^^:master pu
would allow me to push the current pu into pu, and the
commit two commits before it into master, on my public
repository.
The revised rule for updating remote heads is as follows.
$ git-send-pack [--all] <remote> [<ref>...]
- When no <ref> is specified:
- with '--all', it is the same as specifying the full refs/*
path for all local refs;
- without '--all', it is the same as specifying the full
refs/* path for refs that exist on both ends;
- When one or more <ref>s are specified:
- a single token <ref> (i.e. no colon) must be a pattern that
tail-matches refs/* path for an existing local ref. It is
an error for the pattern to match no local ref, or more
than one local refs. The matching ref is pushed to the
remote end under the same name.
- <src>:<dst> can have different cases. <src> is first tried
as the tail-matching pattern for refs/* path.
- If more than one matches are found, it is an error.
- If one match is found, <dst> must either match no remote
ref and start with "refs/", or match exactly one remote
ref. That remote ref is updated with the sha1 value
obtained from the <src> sha1.
- If no match is found, it is given to get_extended_sha1();
it is an error if get_extended_sha1() does not find an
object name. If it succeeds, <dst> must either match
no remote ref and start with "refs/" or match exactly
one remote ref. That remote ref is updated with the sha1
value.

Every time after servicing the connection, select() first fails
with EINTR and ends up waiting for one second before serving the
next client. The sleep() was placed by the original author per
suggestion from the list to avoid spinning on failing select,
but at least this EINTR situation should not result in "at most
one client per second" service limit.

The King Penguin says:
Now, for extra bonus points, maybe you should make "git-rev-list" also

Again I left the v2.6.11-tree tag behind. My bad.
This commit makes sure that we do not barf when pushing a ref
that is a non-commitish tag. You can update a remote ref under
the following conditions:
* You can always use --force.
* Creating a brand new ref is OK.
* If the remote ref is exactly the same as what you are
pushing, it is OK (nothing is pushed).
* You can replace a commitish with another commitish which is a
descendant of it, if you can verify the ancestry between them;
this and the above means you have to have what you are replacing.
* Otherwise you cannot update; you need to use --force.

This allows git-send-pack to push local refs to a destination
repository under different names.
Here is the name mapping rules for refs.
* If there is no ref mapping on the command line:
- if '--all' is specified, it is equivalent to specifying
<local> ":" <local> for all the existing local refs on the
command line
- otherwise, it is equivalent to specifying <ref> ":" <ref> for
all the refs that exist on both sides.
* <name> is just a shorthand for <name> ":" <name>
* <src> ":" <dst>
push ref that matches <src> to ref that matches <dst>.
- It is an error if <src> does not match exactly one of local
refs.
- It is an error if <dst> matches more than one remote refs.
- If <dst> does not match any remote refs, either
- it has to start with "refs/"; <dst> is used as the
destination literally in this case.
- <src> == <dst> and the ref that matched the <src> must not
exist in the set of remote refs; the ref matched <src>
locally is used as the name of the destination.
For example,
- "git-send-pack --all <remote>" works exactly as before;
- "git-send-pack <remote> master:upstream" pushes local master
to remote ref that matches "upstream". If there is no such
ref, it is an error.
- "git-send-pack <remote> master:refs/heads/upstream" pushes
local master to remote refs/heads/upstream, even when
refs/heads/upstream does not exist.
- "git-send-pack <remote> master" into an empty remote
repository pushes the local ref/heads/master to the remote
ref/heads/master.

When pushing into multi-user repository, or when pushing to a
repository from a local repository that has rebased branches
that has been pruned, the destination repository can have head
commits that are missing from the local repository.
This should not matter as long as the local head of the branch
being pushed is a proper superset of the destination branch, but
we ended up trying to run rev-list telling it to exclude objects
reachable from those heads missing from the local repository,
causing it to barf. Prune those heads from the rev-list
parameter list, and make sure we do not try to push a branch
whose remote head is something we lack.

This causes ssh-pull to request objects in prefetch() and read then in
fetch(), such that it reduces the unpipelined round-trip time.
This also makes sha1_write_from_fd() support having a buffer of data
which it accidentally read from the fd after the object; this was
formerly not a problem, because it would always get a short read at
the end of an object, because the next object had not been
