A programming error using the Inflater API led to an infinite
loop within IndexPack, caused by the Inflater returning 0 from
the inflate() method, but it didn't want more input. This happens
when it has reached the end of the stream, or has reached a spot
asking for an external dictionary. Such a case is a failure for us,
and we should abort out.
Thanks to Alex for pointing out that we had 3 implementations of
the inflate rountine, which should be consolidated into one and
use a switch to determine where to load data from.

Added possibility to compare the current entry of a WorkingTreeIterator
to a given DirCacheEntry. This is done to detect whether an entry
in the index is dirty or not. 'Dirty' means that the file in the working tree
is different from what's in the index. Merge algorithms will make use of
this to detect conflicts.

The new Add command adds files to the Git Index.
It uses the DirCache to access the git index. It
works also in case of an existing conflict.
Fileglobs (e.g. *.c) are not yet supported.
The new Add command does add ignored files because
there is no gitignore support in jgit yet.

This patch adds ignore compatibility to jgit. It encompasses
exclude files as well as .gitignore. Uses TreeWalk and
FileTreeIterator to find nodes and parses .gitignore
files when required. The patch includes a simple cache that
can be used to save results and avoid excessive gitignore
parsing.

It is possible that StreamCopyThread will not flush everything
from it's src to it's dst. In most cases StreamCopyThread works
like this:
in loop:
n = src.read(buf);
dst.write(buf, 0, n);
and when we want to flush, we interrupt() StreamCopyThread and it
flushes everything it wrote to dst.
The problem is that our interrupt() could interrupt reading. In this
case we will flush everything we wrote to dst, but not everything
we wrote to src.

JGit did not have support for skipping whitespace when comparing
lines in RawText objects. I added a subclass of RawText that skips
whitespace in its equals and hashCode methods. I used a subclass
rather than adding functionality into RawText so that performance
would not be impacted by extra logic.
This class only supports ignoring all whitespace. Others will follow
that allow other forms of whitespace ignoring.

Under smart HTTP the biDirectionalPipe flag is false, and we return
back immediately at this point in the negotiation process. There is
no need to flush the stream to the client, the request is over and
it will be automatically flushed out by the higher level servlet
that invoked us. Avoiding flush here allows us to only use flush
after a progress message is sent during pack generation.

A Git reference name must never end with ".lock", as it would
confuse any existing C client that tries to obtain a clone of the
repository over the network. Even if the repository isn't on a
local filesystem, it still should ban that suffix.
Because I plan to move LockFile to storage.file and make it a private
implementation detail of the local file system storage model,
we can't rely on its package level SUFFIX field here. Making it
public probably won't work long-term either, as I also plan to
pull storage.file into its own separate project that depends on
the core library.
So, just inline the constant here. Its as foribidden as ":" is.

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.

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.
