When there are conflicts with a recursive merge, the conflicting paths
are stored in unmergedPaths (field in ResolveMerger). Later, when the
MergeResult is constructed in MergeCommand, getBaseCommit is called,
which computes the merge base a second time.
In case of RecursiveMerger, getBaseCommit merges the multiple merge
bases into one. It does this not by creating a new ResolveMerger but
instead calling mergeTrees. The problem with mergeTrees is that at the
end, it checks if unmergedPaths is non-empty and returns false in that
case.
Because unmergedPaths was already non-empty because of the real merge,
it thinks that there were conflicts when computing the merge base again,
when there really were none.
This can be fixed by storing the base commit when computing it and then
returning that instead of computing it a second time.
Note that another possible fix would be to just use a new ResolveMerger
for merging the merge bases instead. This would also remove the need to
remember the old value of dircache, inCore and workingTreeIterator (see
RecursiveMerger#getBaseCommit).

With this change jgit checks for uncommitted changes before a rebase is
started. This is also done by native git. One reason is that an abort
would override such changes. The check is skipped for a non-interactive
rebase when it will result in a fast-forward. In this case there can be
only checkout conflicts but no merge conflicts, so there cannot be an
abort which overrides uncommitted changes.

JGit was not handling certain file/folder conflicts during a checkout
correctly. This was reported by Axel Richard in
http://dev.eclipse.org/mhonarc/lists/jgit-dev/msg02358.html.
This commit fixes this problem.
Still JGit behaves intentionally different than native git.
If HEAD contains a tree, and workingtree, Index and Merge contain a file
with same content ... then JGit allows a conflict free checkout of
Merge. Native git always complains that it doesn't want to overwrite
local changes. But there is no need to update the working tree because
Index and Merge are already equal.
A shell script which shows how native git behaves can be found here.

DfsPackFile.isIndexLoaded() uses the DfsBlockCache.Ref.get() method
to check if the index loaded. However, using the get() method marks
a hot bit in the cache, which can cause the index to never be unloaded
and seem hotter than it really is. Add a has() method which only
checks if the value is not null and does not update the hot bit.

If during an garbage collection old packfiles are deleted it could
happen that on certain platforms the index file can be deleted but the
packfile can't be deleted (because someone locked the file). This led
to repositories with packfiles without corresponding index files. Those
zombie-packfiles potentially consume a lot of space on disk and it is
never tried to delete them again. Try to avoid this situation by
deleting packfiles first and don't try to delete the other files if we
can't delete the packfile. This gives us the chance to delete the
packfile during next GC.
This commit only improves the situation - there is still the chance for
orphan files during packfile deletion. We don't have an atomic delete
of multiple files .

The rebase command now supports squash and fixup. Both actions are not
allowed as the first step of the rebase.
In JGit, before any rebase step is performed, the next commit is
already cherry-picked. This commit keeps that behaviour. In case of
squash or fixup a soft reset to the parent is perfomed afterwards.

A rebase todo file consists of regular non-comment action lines and
comment lines. In case that a regular action line has been commented out
(i.e. prefixed with a hash '#'), the RebaseTodoLine that is representing
this line should hold the values for commitId and shortMessage even
though it's a comment line. This allows to switch between comment and
non-comment easily even after the file has been persisted and reread.

Reading and writing files formatted like the git-rebase-todo files was
hidden in the RebaseCommand. Certain constructs (like leading tabs and
spaces) have not been handled as in native git. Also the upcoming
rebase interactive feature in EGit needs reading/writing these files
independently from a RebaseCommand.
Therefore reading and writing those files has been moved to the
Repository class. RebaseCommand gets smaller because of that and doesn't
have to deal with reading/writing files.
Additional tests for empty todo-list files, or files containing comments
have been added.

ignores an IOException and instead returns an empty map. Repository
is a public API and as such cannot be changed until the next major

If we encounter an I/O error while writing an archive (for example due
to the reader of an HTTP stream closing the connection), the result is
an archive with unclosed entries, causing
TarArchiveOutputStream.finish() to throw IOException("This archives
contains unclosed entries"), hiding the IOException that caused the
early termination.
The unclosed entries are fine: the same exception that occured in the
first place will probably prevent closing the entries before finishing
this partial archive that should be discarded anyway.
It would be nicer to call TarArchiveOutputStream.finish and leave the
underlying OutputStream unclosed --- all callers close it already ---
but that would be a more invasive change so we hold off for now.
