This patch offers a generic interface to allow temp files to be
cached while using an instance of the 'Git' package. If many
temp files are created and destroyed during the execution of a
program, this caching mechanism can help reduce the amount of
files created and destroyed by the filesystem.
The temp_acquire method provides a weak guarantee that a temp
file will not be stolen by subsequent requests. If a file is
locked when another acquire request is made, a simple error is
thrown.

Use rev-list --simplify-merges everywhere. This changes the behaviour
of --subdirectory-filter in cases such as
O -- A -\
\ \
\- B -- M
where A and B bring the same changes to the subdirectory: It now keeps
both sides of the merge. Previously, the history would have been
simplified to 'O -- A'. Merges of unrelated side histories that never
touch the subdirectory are still removed.

The previous ancestor discovery code failed on any refs that are
(pre-rewrite) ancestors of commits marked for rewriting. This means
that in a situation
A -- B(topic) -- C(master)
where B is dropped by --subdirectory-filter pruning, the 'topic' was
not moved up to A as intended, but left unrewritten because we asked
about 'git rev-list ^master topic', which does not return anything.
Instead, we use the straightforward
git rev-list -1 $ref -- $filter_subdir
to find the right ancestor. To justify this, note that the nearest
ancestor is unique: We use the output of
git rev-list --parents -- $filter_subdir
to rewrite commits in the first pass, before any ref rewriting. If B
is a non-merge commit, the only candidate is its parent. If it is a
merge, there are two cases:
- All sides of the merge bring the same subdirectory contents. Then
rev-list already pruned away the merge in favour for just one of its
parents, so there is only one candidate.
- Some merge sides, or the merge outcome, differ. Then the merge is
not pruned and can be rewritten directly.
So it is always safe to use rev-list -1.

This extends the --subdirectory-filter test in t7003 to demonstrate a
rewriting bug: when rewriting two refs A and B such that B is an
ancestor of A, it fails to rewrite B.
The underlying issue is that the rev-list invocation at
git-filter-branch.sh:332 more or less boils down to
git rev-list B --boundary ^A
which outputs nothing because B is an ancestor of A.

All BibTeX entries starts with an @ followed by an entry type. Since
there are many entry types and own can be defined, the pattern matches
legal entry type names instead of just the default types (which would
be a long list). The pattern also matches strings and comments since
they will also be useful to position oneself in a bib-file.

If we are building a thin pack and one of the base objects we would
consider for deltification is missing its OK, the other side already
has that base object. We may be able to get a delta from another
object, or we can simply send the new object whole (no delta).
This change allows a shallow clone to store only the objects which
are unique to it, as well as the boundary commit and its trees, but
avoids storing the boundary blobs. This special form of a shallow
clone is able to represent just the difference between two trees.
Pack objects change suggested by Nicolas Pitre.

This patch emphasizes this change in the release notes (since
I believe this is rather noticeable backwards-incompatible change).
It also adjusts the documentation which still described the old way

When feeding trees on the command line, you can give exactly two
trees, not three nor one; --stdin now supports this "two tree" form on
its input, in addition to accepting lines with one or more commits.
When diffing trees (either specified on the command line or from the
standard input), the -s, -v, --pretty, --abbrev-commit, --encoding,
--no-commit-id, and --always options are ignored, since they do not
apply to trees; and the -m, -c, and --cc options are ignored since
they would be meaningful only with three or more trees, which is not
supported (yet).

Originally dorunq assumed that the queue entry remained first
in the queue after the script eval, and blindly removed it.
However, if the handler calls nukefile, it may not be the
case anymore, and a random queue entry gets dropped instead.
This makes dorunq remove the entry before calling the
script, and adds a global variable to allow other functions
to determine if they are called from within a dorunq handler.

After finding a MIME multi-part message boundary line, the handle_body()
function is supposed to first flush any accumulated contents from the
previous part to the output stream. However, the code mistakenly output
the boundary line it found.
The old code that used one global, fixed-length buffer line[] used an
alternate static buffer newline[] for keeping track of this accumulated
contents and flushed newline[] upon seeing the boundary; when 3b6121f
(git-mailinfo: use strbuf's instead of fixed buffers, 2008-07-13)
converted a fixed-length buffer in this program to use strbuf,these two
buffers were converted to "line" and "prev" (the latter of which now has a
much more sensible name) strbufs, but the code mistakenly flushed "line"
(which contains the boundary we have just found), instead of "prev".
This resulted in the first boundary to be output in front of the first
line of the message.
The rewritten implementation of handle_boundary() lost the terminating
newline; this would then result in the second line of the message to be
stuck with the first line.
The is_multipart_boundary() was designed to catch both the internal
boundary and the terminating one (the one with trailing "--"); this also
was broken with the rewrite, and the code in the handle_boundary() to
handle the terminating boundary was never triggered.

On multiprocessor machines, or with I/O heavy tests (that leave the
CPU waiting a lot), it makes sense to parallelize the tests.
However, care has to be taken that the different jobs use different
trash directories.
This commit does so, by creating the trash directories with a suffix
that is unique with regard to the test, as it is the test's base name.
Further, the trash directory is removed in the test itself if
everything went fine, so that the trash directories do not
pile up only to be removed at the very end.
If a test failed, the trash directory is not removed. Chances are
that the exact error message is lost in the clutter, but you can still
see what test failed from the name of the trash directory, and repeat
the test (without -j).
If all was good, you will see the aggregated results.
Suggestions to simplify this commit came from Junio and René.
There still is an issue with tests that want to run a server process and
listen to a fixed port (http and svn) --- they cannot run in parallel but
this patch does not address this issue.

The Makefile targets 'aggregate-results' and 'clean' pretended to be
independent. This is not true, of course, since aggregate-results
needs the results _before_ they are removed.
Likewise, the tests should have been run already when the results are
to be aggregated.
However, as it is legitimate to run only a few tests, and then aggregate
just those results, so another target is introduced, that depends on all
tests, then aggregates the results, and only then removes the results.
