If the exact rename matrix for a particular ObjectId isn't square we
crashed with an ArrayIndexOutOfBoundsException because the matrix
entries were encoded backwards. The encode function accepts the
source (aka deleted) index first, not second. Add a unit test to
cover this non-square case to ensure we don't have this regression
in the future.

A bug in rename detection would cause file scores to be wrong. The
bug was due to the way rename detection would judge the similarity
between files. If file A has three lines containing 'foo', and file
B has 5 lines containing 'foo', the rename detection phase should
record that A and B have three lines in common (the minimum of the
number of times that line appears in both files). Instead, it would
choose the the number of times the line appeared in the destination
file, in this case file B. I fixed the bug by having the
SimilarityIndex instead choose the minimum number, as it should. I
also added a test case to verify that the bug had been fixed.

An utility method which was in RacyGitTests has been moved to
RepositoryTestCase. Also the javadoc has been improved.
This method allows to wait long enough until the
filesystem-timer has advanced. This is useful when it has to
be guaranteed that two files modifications have different
modification timestamps.

The indexState() method was enhanced to be more configurable. A bitmask
controls which of the optional parts are reported. All data about
the worktree is not reported anymore by this method which makes the
interface more cleaner for users wanting to test only the state of the
index.
This was done because the previous version reported always so much
additional data that it was hard to write good assertions against it.

In order to test racy git situations we have to be able to control
the last-modification timestamps of the filesystem. Since we already
access the modification timestamps of files through an abstraction
(the WorkingTreeIterator) I add a new implementation of this iterator
which allows to map timestamp-ranges to single constant timestamps.
For users of this iterator it looks like all files in that range
have been modified at exactly the same time.
With the help of this iterator a test has been writting which
checkes for racy git handling (smudging, unsmudging, dirty-detection).
Additionally add a method to RepositoryTestCase which encodes the
current index state in one String. This should include info about
pathes, file/index modtime, smudgeState, clean-state. Make
sure timestamps are presented in a way that it is easy to
write assertions against this strings (no concrete milliseconds
but t0,t1,...).
These two topics depend circulary on each other: thats why they have
been squashed in one commit.

This refactoring permits applications to configure global per-process
settings for all packing and easily pass it through to per-request
PackWriters, ensuring that the process configuration overrides the
repository specific settings.
For example this might help in a daemon environment where the server
wants to cap the resources used to serve a dynamic upload pack
request, even though the repository's own pack.* settings might be
configured to be more aggressive. This allows fast but less bandwidth
efficient serving of clients, while still retaining good compression
through a cron managed `git gc`.

the following tests fail under windows because certain inputstreams
are not closed and files cannot be deleted because of that. The
main problem I found is UnpackedObject.InflaterInputStream.close().
This method may throw exceptions found by checkValidEndOfStream()
but doesn't call super.close() before leaving. It is not clear to me
which resources a close() method should release before it throws an
exception. But those reseources which are not published to the
outside and which therefore cannot be closed by other means have to
be closed in all cases.
I changed the close() method to call super.close() under all
circumstances.

By deferring tag sorting until the commit is produced by the walker
we can avoid an infinite loop that was triggered by trying to sort
tags while allocating a commit. This also avoids needing to look

File pairs that are very dissimilar during a diff were not being
broken apart into their constituent ADD/DELETE pairs. The leads to
sub-optimal rename detection. Take, for example, this situation:
A file exists at src/a.txt containing "foo". A user renames src/a.txt
to src/b.txt, then adds a new src/a.txt containing "bar".
Even though the old a.txt and the new b.txt are identical, the
rename detection algorithm would not detect it as a rename since
it was already paired in a MODIFY. I added code to split all
MODIFYs below a certain score into their constituent ADD/DELETE
pairs. This allows situations like the one I described above to be
more correctly handled.
