Currently, there is no way to read the content
of the Git Configuration in a way that would
allow to list all configured values generically.
This change extends the Config class in such a
way as to being able to get a list of sections and
to get a list of names for any given section or
subsection.
This is required in able to implement proper
configuration handling in EGit (show all the
content of a given configuration similar to
"git config -l").

Windows doesn't permit us to edit a file in-place with Perl.
So create backup files when we perform the edit, and remove them
when we are done. This is a tad slower on POSIX systems, but is
much more portable.

On Windows, FS_Win32_Cygwin has been used if a Cygwin Git installation
is present in the PATH. Assuming that the user works with the Cygwin
Git installation may result in unnecessary overhead if he actually
does not.
Applications built on top of jgit may have more knowledge on the
actually used Git client (Cygwin or not) and hence should be able to
configure which FS to use accordingly.

WorkDirCheckout. This change doesn't add/modify any tests semantically
but refactors ReadTreeTest so that a different implementations of
checkout can be tested. This was done to allow DirCacheCheckout to be
tested without rewriting all these tests.

The J2SE NIO APIs require that FileChannel close the underlying file
descriptor if a thread is interrupted while it is inside of a read or
write operation on that channel. This is insane, because it means we
cannot share the file descriptor between threads. If a thread is in
the middle of the FileChannel variant of IO.readFully() and it
receives an interrupt, the pack will be automatically closed on us.
This causes the other threads trying to use that same FileChannel to
receive IOExceptions, which leads to the pack getting marked as
invalid. Once the pack is marked invalid, JGit loses access to its
entire contents and starts to report MissingObjectExceptions.
Because PackWriter must ensure that the chosen pack file stays
available until the current object's data is fully copied to the
output, JGit cannot simply reopen the pack when its automatically
closed due to an interrupt being sent at the wrong time. The pack may
have been deleted by a concurrent `git gc` process, and that open file
descriptor might be the last reference to the inode on disk. Once its
closed, the PackWriter loses access to that object representation, and
it cannot complete sending the object the client.
Fortunately, RandomAccessFile's readFully method does not have this
problem. Interrupts during readFully() are ignored. However, it
requires us to first seek to the offset we need to read, then issue
the read call. This requires locking around the file descriptor to
prevent concurrent threads from moving the pointer before the read.
This reduces the concurrency level, as now only one window can be
paged in at a time from each pack. However, the WindowCache should
already be holding most of the pages required to handle the working
set for a process, and its own internal locking was already limiting
us on the number of concurrent loads possible. Provided that most
concurrent accesses are getting hits in the WindowCache, or are for
different repositories on the same server, we shouldn't see a major
performance hit due to the more serialized loading.
I would have preferred to use a pool of RandomAccessFiles for each
pack, with threads borrowing an instance dedicated to that thread
whenever they needed to page in a window. This would permit much
higher levels of concurrency by using multiple file descriptors (and
file pointers) for each pack. However the code became too complex to
develop in any reasonable period of time, so I've chosen to retrofit
the existing code with more serialization instead.

The CommitCommand should take care to create a merge commit if the file
$GIT_DIR/MERGE_HEAD exists. It should then read the parents for the merge
commit out of this file. It should also take care that when commiting
a merge and no commit message was specified to read the message from
$GIT_DIR/MERGE_MSG.
Finally the CommitCommand should remove these files if the commit
succeeded.

The strings are externalized into the root resource bundles.
The resource bundles are stored under the new "resources" source
folder to get proper maven build.
Strings from tests are, in general, not externalized. Only in
cases where it was necessary to make the test pass the strings
were externalized. This was typically necessary in cases where
e.getMessage() was used in assert and the exception message was
slightly changed due to reuse of the externalized strings.

Rather than holding onto the PackedObjectLoader, only hold the
PackFile and the object offset. During a reuse copy that is all
we should need to complete a reuse, and the other parts of the
PackedObjectLoader just waste memory.
This change reduces the per-object memory usage of a PackWriter by
32 bytes on a 32 bit JVM using only OFS_DELTA formatted objects.
The savings is even larger (by another 20 bytes) for REF_DELTAs.
This is close to a 50% reduction in the size of ObjectToPack,
making it rather worthwhile to do.
Beyond the memory reduction, this change will help to make future
refactoring work easier. We need to redo the API used to support
copying data, and disconnecting it from the PackedObjectLoader is
a good first step.

Rather than keep track of both the position of the object, and the
position of its data, just keep track of the number of bytes used
by the object's header in the pack. This shaves 4 bytes out of the
size of the PackedObjectLoader instances.
We also can defer the addition instruction to the materialize()
operation, avoiding it entirely if the caller never actually uses
the loader. This may be relevant for PackWriter invocations,
where only 1 loader gets chosen for a given object, even though
the object may appear on disk in more than one pack file.
Error reporting is now simplified, as we can rely on the object
offset rather than its data offset. This is the value displayed
by pack debugging tools like `git verify-pack -v`, so its better
to use that in our own errors.
Because nobody needs getDataOffset() now, we can drop that from
the public API.

Originally when I wrote this code I had hoped to use OffsetCache
to also implement the UnpackedObjectCache. But it turns out they
need rather different code, and it just wasn't worth trying to
reuse the OffsetCache base class.
Before doing any major refactoring or code cleanups here, squash the
two classes together and delete OffsetCache. As WindowCache is our
only subclass, this is pretty simple to do. We also get a minor
code reduction due to less duplication between the two classes,
and the JIT should be able to do a better job of optimization here
as we can define types up front rather than relying on generics
that erase back to java.lang.Object.
