* changes:
Support [<ref>]@{upstream} revision syntax
Support parsing previous checkout as a revision expresion.
Allow a @ without branch in revision syntax
Refactored method to find branches from which a commit is reachable
The method uses some heuristics to obtain much better performance
than isMergeBase.
Since I wrote the relevant code in the method I approve the license
change from EPL to EDL implied by the move.

Teach BranchTrackingStatus to handle tracking of local branches
EGit wasn't able to decorate local branches tracking another local
branch with number of commits the checked out local branch differs from
the other local branch it's tracking.

Improve ours/theirs conflict markers for rebase, cherry-pick
On conflicts in rebase or cherry-pick, the conflict markers were like
this:
<<<<<<< OURS
a
=======
b
>>>>>>> THEIRS
This is technically correct, but it could be better.
It's especially confusing during a rebase, where the meaning of
OURS/THEIRS is not obvious. The intuition is that "ours" is the commits
that "I" did before the rebase, but it's the other way around because of
the way rebase works. See various bug reports and stackoverflow
discussions.
With this change, in the case of a cherry-pick while on master, the
markers will be like this:
<<<<<<< master
a
=======
b
>>>>>>> bad1dea Message of the commit I'm cherry-picking
In the case of a "git rebase master":
<<<<<<< Upstream, based on master
a
=======
b
>>>>>>> b161dea Message of a commit I'm rebasing
It's not "master" because that would only be correct for the first
cherry-pick during a rebase, after that, it's master + already
cherry-picked commits.
And in the case of a "git pull --rebase":
<<<<<<< Upstream, based on branch 'master' of git@example.org:repo
a
=======
b
>>>>>>> b161dea Message of a commit I'm rebasing

Implement wasDeltaAttempted() in DfsObjectRepresentation.
In DFS, everything is stored in a pack but only objects in a pack with
source GC or UNREACHABLE_GARBAGE have had delta compression attempted.
Expose the PackSource setter and getter on DfsPackDescription in order
to implement wasDeltaAttempted.

Do not delta compress objects that have already tried to compress.
If an object is in a pack file already, delta compression will not
attempt to re-compress it. This assumes that the previous
packing already performed the optimal compression attempt, however,
the subclasses of StoredObjectRepresentation may use other heuristics
to determine if the stored format is optimal.

Make CheckoutCommand pass modified files through result
This change makes CheckoutCommand pass the list of modified files

Ensure a directory exists before trying to create/merge a file into it.
Since git doesn't keep track of empty directories, they should be
created first. Test case included demonstrates that using
StashApplyCommand(). Bugfix is applied to the DirCacheCheckout class,
because StashApplyCommand() uses it internally to apply a stash.

JGit allows to create commits which have duplicate parents: e.g. a
commit X has first parent Y and second parent Y. Such commits are not
handled correctly by PlotCommit leading to wrong display of the history
in EGit. In such cases there is a never ending passing line drawn beside
all commits younger than the commit with duplicate parents. This commit
fixes this by explicitly checking for duplicate parents.
In a different commit we should fix JGit not to create commits with
duplicate parents. I think native git also doesn't allow such commits,
although history display in native git (gitk, git log --graph) is not
damaged by such commits.

Implements a garbage collector for FileRepositories. Main ideas are
copied from the garbage collector for DFS based repos
(DfsGarbageCollector). Added functionalities are
- pruning loose objects
- handling of the index
- packing refs
- handling of reflogs (objects referenced from reflog will not be
pruned/)
These are features of a GC which are not handled in this change and
which should come with subsequent changes:
- unpacking packed objects into loose objects (to support that pruning
packed objects doesn't delete them until they are older than two weeks)
- expiration of reflogs
- support for configuration parameters (e.g. gc.pruneExpire)

Expose class DfsReader and method DfsPackFile.hasObject() as public.
Applications may want to be able to inquire about some details of
the storage of a repository. Make this possible by exposing some
simple accessor methods.
Expose method DfsObjDatabase.clearCache() as protected, allowing
implementing subclasses to dump the cache if necessary, and force
it to reload on a future request.

Again teach ResolveMerger to create more correct DirCacheEntry's
Currently, after a merge/cherry-pick/rebase, all index entries are
smudged as the ResolveMerger never sets entry lengths and/or
modification times. This change teaches it to re-set them at least for
things it did not touch. The other entries are then repaired when the
index is persisted, or entries are checked out.
The first attempt to get this in was commit
3ea694c252 which has been reverted.
Since then some fixes to ResolveMerger and a few more tests have
been added which check situations where the index is not matching
HEAD before we merge.

Support parsing previous checkout as a revision expresion.
Repository.resolve can only return an ObjectId and will
continue to do so, but another method, simplify(), will
be able to return a branch name for some cases.
Previous checkouts can be specified as @{-n}, where n is an
integer speifying the n:th previous branch. The result
is the branch name, unless the checkout was a detached head,
in which case the object id is returned. Since the result
is a branch it may be followed by a references to the reflog,
such as @{-1}@{1} if necessary.
A simple expression like "master" is resolved to master in
simplify, but anything starting with refs gets resolved to
its object id, even if it is a branch.
A symbolic ref is resolved to its leaf ref, e.g. "HEAD" might
be resolved to "master".

No branch before @ is interpreted as the currently checked out branch.
For detached heads it would be HEAD, but normally it is the branch
that HEAD refers to.

* stable-2.0:
Improve performance of persisting an index by magnitudes

Improve performance of persisting an index by magnitudes
When updating smudged entries use a pathfilter to iterate only over
working tree files which have an associated smudged index entry.
Commit dac66672df introduced that we
check and update smudged entries while persisting a dircache. Before
that commit adding a file to git caused file i/o for the index file,
the object database (to store new content) and all files we wanted to
add (to read new content). After that commit we have additionally file
i/o for every file in the working tree (even ignored files).
Especially on windows iterating over the working tree can be very
time consuming. This decreased the performance of persisting a dircache
dramatically (I measured factors 4 to 10 while adding a file to linux
kernel repo). One could easily see this effect when dragging&dropping
modified files in a linux kernel repo in the egit staging view.

I have unfortunately introduced a few bugs in the native Git client
over the years. 1.7.5 is unable to send chunked requests correctly,
resulting in corrupt data at the server. Ban this client whenever
it uses chunked encoding with an error message.
Prior to some more recent versions, git push over HTTP failed to
report status information and error messages due to a race within
the client and its helper process. Check for these bad versions and
send errors as messages before the status report, enabling users
to see the failures on their terminal.
