Remove the unnecessary parameter and branch, making

Due to the Git internal sort order a directory is sorted as if it ended
with a '/', this means that the path filter didn't set the last possible
matching entry to the correct value. In the reported issue we had the
following filters.
org.eclipse.jgit.console
org.eclipse.jgit
As an optimization we throw a StopWalkException when the walked tree
passes the last possible filter, which was this:
org.eclipse.jgit.console
Due to the git sorting order, the tree was processed in this order:
org.eclipse.jgit.console
org.eclipse.jgit.test
org.eclipse.jgit
At org.eclipse.jgit.test we threw the StopWalkException preventing the
walk from completing successfully.
A correct last possible match should be:
org.eclipse.jgit/
For simplicit we define it as:
org/eclipse/jgit/
This filter would be the maximum if we also had e.g. org and org.eclipse
in the filter, but that would require more work so we simply replace all
characters lower than '/' by a slash.
We believe the possible extra walking does not not warrant the extra
analysis.

Writing CLI test cases is tedious because of all the formatting and
escaping subtleties needed when comparing actual output with what's
expected. While creating a test case the two new functions are to be
used instead of the existing execute() in order to prepare the correct
command and expected output and to generate the corresponding test code
that can be pasted into the test case function.

LockFile.unlock() erroneously tried to delete the non-existing lock

Instead of forcing the implementation of the DFS backend to handle
making sure the extension bits are set correctly, have the common
callers in JGit set the extension at the same time they supply the
file sizes to the pack description. This simplifies assumptions for
an implementation of the DFS backend.

Unlike the OS or Java rename this method will (on *nix) try (on Windows)
replace the target with the source provided the target does not exist,
the target does exist and is a file, or if it is a directory which only
contains directories. In the latter case the directory hierarchy will be
deleted.
If the initial rename fails and the target is an existing file the the
target file will be deleted first and then the rename is retried.

When running the garbage collection for a repository it is often
interesting to compare the repository statistics from before and after
the garbage collection to understand the effect of the garbage
collection. This is why it makes sense that the
GarbageCollectionCommand provides a method to retrieve the repository
statistics before running the garbage collection.
So far without running the garbage collection the repository statistics
can only be retrieved by using JGit internal classes. This is what EGit
and Gerrit do at the moment, but it would be better to have an API for
this.

Only on Windows the rename operation which renames temporary Packfiles
(and index-files and bitmap-files) sometime fails. This happens only
when renaming a temporary Packfile to a Packfile which already exists.
Such situations occur if you run GC twice on a repo without modifying
the repo inbetween.
In such situations there was bug in GC which led to a corrupted repo
whithout any packfiles anymore. This commit fixes the problem by
introducing a utility method which renames a file and throws an
IOException if it fails. This method also takes care to repeat a
failing rename if our FS class has found out we are running on a
platform with a unreliable File.renameTo() method.
I am searching for a better solution because even with this utility
method in hand a GC on a already GC'ed repo will fail on Windows. But
at least with this fix we will not produce corrupted repos anymore.

With JGit it is possible to write reflog entries where new objectid and
old objectid is null. Such reflogs cause FileRepository GC to crash
because it doesn't expect the new objectid to be null. One case where
this happened is in Gerrit's allProjects repo. In the same way as we
expect the old objectid to be potentially null we should also ignore
null values in the new objectid column.

The bitmap code in PackWriter knows exactly when to use a pack as
a "cached pack". It enables cached pack usage only when the pack
has a bitmap and its entire closure of objects needs to be sent.
This is a much simpler code path to maintain, and JGit actually
has a way to write the necessary index.

Just counting objects is not sufficient. There are some race
conditions with receive packs and delta base completion that
may confuse such a simple algorithm.
Instead always do the larger set computations, and rely on the
PackWriter having no objects pending as the way to avoid creating
an empty pack file.

Let the pack description copy the relevant stats values. This
moves it out of the garbage collector and compactor algorithms,
co-locating with something that might care.
Remove some unnecessary code from the DfsPackCompactor, the stats
tracks the same information and can supply it.
