This adds --bisect-vars option to rev-list. The output is suitable
for `eval` in shell and defines five variables:
- bisect_rev is the next revision to test.
- bisect_nr is the expected number of commits to test after
bisect_rev is tested.
- bisect_good is the expected number of commits to test
if bisect_rev turns out to be good.
- bisect_bad is the expected number of commits to test
if bisect_rev turns out to be bad.
- bisect_all is the number of commits we are bisecting right now.
The documentation text was partly stolen from Johannes
Schindelin's patch.

The new configuration variable core.deltaBaseCacheLimit allows the
user to control how much memory they are willing to give to Git for
caching base objects of deltas. This is not normally meant to be
a user tweakable knob; the "out of the box" settings are meant to
be suitable for almost all workloads.
We default to 16 MiB under the assumption that the cache is not
meant to consume all of the user's available memory, and that the
cache's main purpose was to cache trees, for faster path limiters
during revision traversal. Since trees tend to be relatively small
objects, this relatively small limit should still allow a large
number of objects.
On the other hand we don't want the cache to start storing 200
different versions of a 200 MiB blob, as this could easily blow
the entire address space of a 32 bit process.
We evict OBJ_BLOB from the cache first (credit goes to Junio) as
we want to favor OBJ_TREE within the cache. These are the objects
that have the highest inflate() startup penalty, as they tend to
be small and thus don't have that much of a chance to ammortize
that penalty over the entire data.

I was using "branch" to mean "head", but that's perhaps a little

The --nonet option prevents xsltproc from going to the network to find
anything. But it always tries to find them locally first, so for a
user with the necessary docbook stylesheets installed the build will
work just fine without xsltproc attempting to use the network; all

This patch adds support for a dummy remote '.' to avoid having
to declare a fake remote like
[remote "local"]
url = .
fetch = refs/heads/*:refs/heads/*
Such a builtin remote simplifies the operation of "git-fetch",
which will populate FETCH_HEAD but will not pretend that two
repositories are in use, will not create a thin pack, and will
not perform any useless remapping of names. The speed
improvement is around 20%, and it should improve more if
"git-fetch" is converted to a builtin.
To this end, git-parse-remote is grown with a new kind of
remote, 'builtin'. In git-fetch.sh, we treat the builtin remote
specially in that it needs no pack/store operations. In fact,
doing git-fetch on a builtin remote will simply populate
FETCH_HEAD appropriately.
The patch also improves of the --track/--no-track support,
extending it so that branch.<name>.remote items referring '.'
can be created. Finally, it fixes a typo in git-checkout.sh.

Sergey Vlasov, Andy Parkins and Alex Riesen all pointed out that it
is possible for a single invocation of receive-pack to be given more
refs than the OS might allow us to pass as command line parameters
to a single hook invocation.
We don't want to break these up into multiple invocations (like
xargs might do) as that makes it impossible for the pre-receive
hook to verify multiple related ref updates occur at the same time,
and it makes it harder for post-receive to send out a single batch
notification.
Instead we pass the reference data on a pipe connected to the
hook's stdin, supplying one ref per line to the hook. This way a
single hook invocation can obtain an infinite amount of ref data,
without bumping into any operating system limits.

In order to track and build on top of a branch 'topic' you track from
your upstream repository, you often would end up doing this sequence:
git checkout -b mytopic origin/topic
git config --add branch.mytopic.remote origin
git config --add branch.mytopic.merge refs/heads/topic
This would first fork your own 'mytopic' branch from the 'topic'
branch you track from the 'origin' repository; then it would set up two
configuration variables so that 'git pull' without parameters does the
right thing while you are on your own 'mytopic' branch.
This commit adds a --track option to git-branch, so that "git
branch --track mytopic origin/topic" performs the latter two actions
when creating your 'mytopic' branch.
If the configuration variable branch.autosetupmerge is set to true, you
do not have to pass the --track option explicitly; further patches in
this series allow setting the variable with a "git remote add" option.
The configuration variable is off by default, and there is a --no-track
option to countermand it even if the variable is set.

The script sort_glossary.pl turns each use of "term" into a link to the
definition of "term". To avoid mangling links like
gitlink:git-term[1]
it doesn't replace any occurence of "term" preceded by "link:git-".
This fails for gitlink:git-symbolic-ref[1] when substituting for "ref".
So instead just refuse to replace anything preceded by a "-".
That could result in missing some opportunities, but that's a less
annoying error.
Actually I find the automatic substitution a little distracting; some
day maybe we should just run it once and commit the result, so it can
be hand-tuned.

Bill Lear pointed out that it is easy to send out notifications of
changes with the update hook, but successful execution of the update
hook does not necessarily mean that the ref was actually updated.
Lock contention on the ref or being unable to append to the reflog
may prevent the ref from being changed. Sending out notifications
prior to the ref actually changing is very misleading.
To help this situation I am introducing two new hooks to the
receive-pack flow: pre-receive and post-receive. These new hooks
are invoked only once per receive-pack execution and are passed
three arguments per ref (refname, old-sha1, new-sha1).
The new post-receive hook is ideal for sending out notifications,
as it has the complete list of all refnames that were successfully
updated as well as the old and new SHA-1 values. This allows more
interesting notifications to be sent. Multiple ref updates could
be easily summarized into one email, for example.
The new pre-receive hook is ideal for logging update attempts, as it
is run only once for the entire receive-pack operation. It can also
be used to verify multiple updates happen at once, e.g. an update
to the `maint` head must also be accompained by a new annotated tag.
Lots of documentation improvements for receive-pack are included
in this change, as we want to make sure the new hooks are clearly
explained.

This patch adds support to archimport for remapping the branch
names to match those used in git more closely. This is useful
for projects that migrate to git (as opposed to users that want
to use git on Arch-based projects). For example, one can choose
an Arch branch name and call it "master".
The new command-line syntax works even if there is a colon in
a branch name, since only the part after the last colon is taken
to be the git name (git does not allow colons in branch names).
The new feature is implemented so that archives rotated every
year can also be remapped into a single git archive.

Some file systems that can host git repositories and their working copies
do not support symbolic links. But then if the repository contains a symbolic
link, it is impossible to check out the working copy.
This patch enables partial support of symbolic links so that it is possible
to check out a working copy on such a file system. A new flag
core.symlinks (which is true by default) can be set to false to indicate
that the filesystem does not support symbolic links. In this case, symbolic
links that exist in the trees are checked out as small plain files, and
checking in modifications of these files preserve the symlink property in
the database (as long as an entry exists in the index).
Of course, this does not magically make symbolic links work on such defective
file systems; hence, this solution does not help if the working copy relies
on that an entry is a real symbolic link.
