git-svn: Reduce temp file usage when dealing with non-links
git-svn: Make it incrementally faster by minimizing temp files
Git.pm: Add faculties to allow temp files to be cached
Currently, in sub 'close_file', git-svn creates a temporary file and
copies the contents of the blob to be written into it. This is useful
for symlinks because svn stores symlinks in the form:
link $FILE_PATH
Git creates a blob only out of '$FILE_PATH' and uses file mode to
indicate that the blob should be interpreted as a symlink.
As git-hash-object is invoked with --stdin-paths, a duplicate of the
link from svn must be created that leaves off the first five bytes,
i.e. 'link '. However, this is wholly unnecessary for normal blobs,
though, as we already have a temp file with their contents. Copying
the entire file gains nothing, and effectively requires a file to be
written twice before making it into the object db.
This patch corrects that issue, holding onto the substr-like
duplication for symlinks, but skipping it altogether for normal blobs
by reusing the existing temp file.

Currently, git-svn would create a temp file on four occasions:
1. Reading a blob out of the object db
2. Creating a delta from svn
3. Hashing and writing a blob into the object db
4. Reading a blob out of the object db (in another place in code)
Any time git-svn did the above, it would dutifully create and then
delete said temp file. Unfortunately, this means that between 2-4
temporary files are created/deleted per file 'add/modify'-ed in
svn (O(n)). This causes significant overhead and helps the inode
counter to spin beautifully.
By its nature, git-svn is a serial beast. Thus, reusing a temp file
does not pose significant problems. "truncate and seek" takes much
less time than "unlink and create". This patch centralizes the
tempfile creation and holds onto the tempfile until they are deleted
on exit. This significantly reduces file overhead, now requiring
at most three (3) temp files per run (O(1)).

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.

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.

The post-update hook, which is required to be enabled in order for
the repository to be accessible over HTTP, is not enabled by
chmod a+x anymore, but instead by dropping the .sample suffix.
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
and fixes t/t5540-http-push.sh, which was broken for 1.5 month

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.

Some repositories use a deep branching strategy, such as:
branches/1.0/1.0.rc1
branches/1.0/1.0.rc2
branches/1.0/1.0.rtm
branches/1.0/1.0.gold
Only allowing a single glob stiffles this.
This change allows for a single glob 'set' to accept this deep
branching strategy.
The ref glob depth must match the branch glob depth. When using
the -b or -t options for init or clone, this is automatically
done.
For example, using the above branches:
svn-remote.svn.branches = branches/*/*:refs/remote/*/*
gives the following branch names:
1.0/1.0.rc1
1.0/1.0.rc2
1.0/1.0.rtm
1.0/1.0.gold

This adds a make target which can be used to try to execute certain shell
constructs which are required for compiling and running git.
This patch provides a test for the $() notation for command substition
which is used in the Makefile and extensively in the git scripts.
The make target is named in such a way as to be a hint to the user that
SHELL_PATH should be set to an appropriate shell. If the shell command
fails, the user should receive a message similar to the following:
