Added characters to be escaped in file name patterns

Originally, characters could not be escaped in FileNameMatcher patterns.
This breaks file name matching when escaped brackets "\[" and "\]" are
used in the pattern. A fix has been implemented to allow for any
character to be escaped by prepending it with a '\'

Fix hardcoded use of target/trash in LocalDiskRepositoryTestCase

`pwd`/target is only valid in Maven Reactor builds where Maven
has moved into the project directory and created a target for
the build output. Most other build systems do not use "target"
and may not even perform a directory change between test suites.

Rewrite LocalDiskRepositoryTestCase's temporary directory code
to use the system specified location and create new unique names.
This prevents fixes between concurrently running tests and allows
the caller to specify the root using java.io.tmpdir.

Update the surefire command lines to use target within each project as
the system temporary directory during unit testing, preventing JGit's
own test suite from writing to /tmp or somewhere like C:\tmp.

Allow PreUploadHook.onSendPack to send messages to the client

Before transmitting to the client a hook may want to send along
a text message ahead of the pack, such as a "message of the day".
Enable this usage by mirroring the message sending API from
ReceivePack on the UploadPack instance, using the side band.

Use NullOutputStream not DisabledOutputStream in UploadPack

The stream should not throw IllegalStateException if it is off.
Flush the stream after the hook runs, in case any messages need

ArchiveCommand: make archive formats non-inner classes

Drop dependency by ArchiveCommand.Format interface on commons-compress

Otherwise, anyone trying to implement a new format would have to
depend on commons-compress, even if using a different underlying
library to write the archive.

Remove dependency by ArchiveCommand on archive formats

Provide static registerFormat and unregisterFormat methods to allow
formats to register themselves without the ArchiveCommand code being
aware of them.

Register the basic "zip" and "tar" support at bundle activation time
(and deregister them when unloading the bundle).  For anyone using
this code as an OSGi plugin it should continue to just work.

The jgit program does not load org.eclipse.jgit.pgm as an OSGi bundle,
so let the Archive command register the formats it uses explicitly
with registerFormat.

Move ArchiveCommand into standard porcelain API

Allow use of ArchiveCommand without depending on the jgit command-line
tools.

To avoid complicating the process of installing and upgrading JGit,
this does not add a dependency by the org.eclipse.jgit bundle on
commons-compress.  Instead, the caller is responsible for registering
any formats they want to use by calling ArchiveCommand.registerFormat.

This patch puts functionality that requires an archiver into a
separate org.eclipse.jgit.archive bundle for people who want it.  One
can use it by calling ArchiveCommand.registerFormat directly to
register its formats or by relying on OSGi class loading to load
org.eclipse.jgit.archive.FormatActivator, which takes care of
registration automatically.

Once the appropriate formats are registered, you can make a tar or zip
from a git tree object as follows:

	ArchiveCommand cmd = git.archive();
	try {
		cmd.setTree(tree).setFormat(fmt).setOutputStream(out).call();
	} finally {
		cmd.release();
	}

Release ArchiveCommand's ObjectReader in call()

Make call() release all private resources so instead of using a
pattern like

	ArchiveCommand cmd = git.archive();
	try {
		cmd.setTree(tree)
			. ...
			.call();
	} finally {
		cmd.release();
	}

callers can just use git.archive().setTree(tree)....call() directly.

This involves pushing more work out of parameter setters and into
call() so the ObjectReader is not allocated and potentially leaked
before then.

Maintain list of archive formats in one place

Add a static start() method to FormatActivator to allow outside
classes such as the Archive subcommand of the jgit program to use it
without a BundleContext.  This way, the list of formats only has to be
maintained in one place.

While at it, build a list of registered formats at start() time, so
stop() doesn't have to repeat the same list of formats.
