This reverts commit 7aa54967a2.
The unit test dependend upon the specific order of names that
listFiles() returned members in. The order is completely undefined
and may differ even on different versions of Linux based systems.
A proper unit test for this code would have considered both cases,
where the deletion function was able to remove an empty subdirectory,
or fail to remove a subdirectory because a file was still present
within. This is not such a test.

Adds a new method getConflictingStageStates() which returns a
Map<String, StageState> (path to stage state). StageState is an enum for
all possible stage combinations (BOTH_DELETED, ADDED_BY_US, ...).
This can be used to implement the conflict text for unmerged paths in
output of "git status" or in EGit for decorations/hints.

Commit 3344b93c erroneously exported the package org.eclipse.jgit.lib
from the org.eclipse.jgit.test bundle which made this a split package
since the bundle org.eclipse.jgit exports the same package.
Split packages are evil in general and most probably caused the build
cycle errors observed recently when importing the jgit projects in
Eclipse [1].

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.

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.

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 walk logic does not use RevWalk because it needs to walk all paths
to each of the requested commits, keeping track of each path along which
the commit was found in the RevCommit subclass. From these paths, a
single "best" path is chosen based on the total path length, with a
penalty applied for paths that traverse merges.
This functionality parallels "git name-rev".

Rebase computes the list of commits that are included in
the merges, just like Git does, so do not try to include
the merge commits. Re-recreating merges during rebase is
a bit more complicated and might be a useful future extension,
but for now just linearize during rebase.

A pack bitmap index is an additional index of compressed
bitmaps of the object graph. Furthermore, a logical API of the index
functionality is included, as it is expected to be used by the
PackWriter.
Compressed bitmaps are created using the javaewah library, which is a
word-aligned compressed variant of the Java bitset class based on
run-length encoding. The library only works with positive integer
values. Thus, the maximum number of ObjectIds in a pack file that
this index can currently support is limited to Integer.MAX_VALUE.
Every ObjectId is given an integer mapping. The integer is the
position of the ObjectId in the complete ObjectId list, sorted
by offset, for the pack file. That integer is what the bitmaps
use to reference the ObjectId. Currently, the new index format can
only be used with pack files that contain a complete closure of the
object graph e.g. the result of a garbage collection.
The index file includes four bitmaps for the Git object types i.e.
commits, trees, blobs, and tags. In addition, a collection of
bitmaps keyed by an ObjectId is also included. The bitmap for each entry
in the collection represents the full closure of ObjectIds reachable
from the keyed ObjectId (including the keyed ObjectId itself). The
bitmaps are further compressed by XORing the current bitmaps against
prior bitmaps in the index, and selecting the smallest representation.
The XOR'd bitmap and offset from the current entry to the position
of the bitmap to XOR against is the actual representation of the entry
in the index file. Each entry contains one byte, which is currently
used to note whether the bitmap should be blindly reused.

CloneCommand has been creating fetch refspecs like this on bare clones:
[remote "origin"]
url = ssh://example.com/my-repo.git
fetch = +refs/heads/*:refs/heads//*
As you can see, the destination ref pattern has a superfluous slash.
It looks like this behaviour has always been the case for CloneCommand,
at least since cc2197ed when code catering to bare-clone fetch refspecs
was added. That was released with JGit v1.0 almost 2 years ago, so
there will probably be some bare repos in the wild which will have been
cloned with JGit and have these corrupted refspecs.
The effect of the corrupted fetch refspec is quite interesting. Up to
and including JGit 2.0, the corrupt refspec was tolerated and fetches
would work as intended with no indication to the user that anything was
amiss. With JGit 2.1, a change was introduced which made JGit less
tolerant, and fetches now attempt to update the non-existing ref
"refs/heads//master". No exception is raised, but the real ref -
"refs/heads/master" - is not updated.
This behaviour was noticed by a user of Agit (which does bare clones by
default and recently updated from JGit v2.0 to v2.2), reported here:
https://github.com/rtyley/agit/issues/92
If you run C-Git fetch on a bare-repo cloned by JGit, it flat-out
rejects the refspec (checked against v1.7.10.4):
fatal: Invalid refspec '+refs/heads/*:refs/heads//*'
Incidentally, C-Git does not create an explicit fetch refspec at all
when performing a bare clone - the full remote config generated by C-Git
looks like this:
[remote "origin"]
url = ssh://example.com/my-repo.git
Using JGit on such a repository works fine, so omitting the fetch
refspec entirely is also an option.

This has the same logic as isNameConflicting, but instead of only
returning a boolean, it returns a collection of names that conflict.
It will be used in EGit to provide a better message to the user when
validating a ref name, see Ibea9984121ae88c488858b8a8e73b593195b15e0.
Existing implementations of isNameConflicting could be rewritten like
this:
return !getConflictingNames(name).isEmpty();
But I'm not sure about that, as isNameConflicting can be implemented in
a faster way than getConflictingNames.
