Make JGit test work with both hamcrest 1.1 (juno) and 1.3 (kepler)
The hamcrest library has moved things around. This problem applies only
to the test, not plugin runtime.

IndexDiff: Provide stage state for conflicting entries
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.

Skip main thread test in ThreadSafeProgressMonitor
update(int) is only invoked from a worker thread, in JGit's case
this is DeltaTask. The Javadoc of TSPM suggests update should only
ever be used by a worker thread.
Skip the main thread check, saving some cycles on each run of the
progress monitor.

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.

Add additional FastForwardMode enums for different config contexts

it is set or get from. E.g. FastForwardMode.FF_ONLY for

DirCacheCheckout: Fix handling of files not in index
When a file is not in the index and neither contents nor mode differ
between "head" and "merge", the index state should be kept. If they
differ, a checkout conflict should occur. This is described in Git's
git-read-tree.txt.
JGit used to replace the index state with "merge" in both of the above
cases.
A confusing effect of this was that when one removed a file and then did
a rebase, the file silently reappeared again.
The changes to dir/file conflict handling are a consequence of this
change, as the index handling change made tests in DirCacheCheckoutTest
break. I compared these cases to C Git and the new behavior there also
matches what C Git does.

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.

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".

Git API does not declare GitAPIException call() and related cleanups
All commands should throw a GitAPIException so new exceptions can be
added without breaking the builds of old code, i.e. anyone that calls
a Git API should catch GitAPIException and not just the currently known
exceptions.
Now the only checked exceptions on Git API calls are GitException and
subclasses of it. New checked exceptions that are subclasses of
GitException may be added without breaking the API.
Javadoc for GitAPIException is declared on GitCommand and
inherited to subclasses. JGitInternalException is not explicitly
documented anymore.
Unfortunately this change itself breaks the API. The intention is
that it shall be possible to add new checked subclasses of
GitAPIException without breaking the API.

DirCacheCheckout and CanonicalTreeParser cooperate. CanonicalTreeParser
can detect malformed, potentially malicious tree entries and sets a
flag, while DirCacheCheckout refuses to work with such paths.
Malicious tree entries are ".", "..", ".git" (case insensitive), any
name containing '/' and (on Windows '\') and also (on Windows)
any paths ending in a combination of '.' or space or containing a ':'.
We also forbid all special names like "con" etc on Windows.
Some of the test can execute on any platform by enabling partial
platform emulation.
A new runtime exception, InvalidPathException, is introduced. For
backwards compatibility it extends InvalidArgumentException.

Generate conflicts and index updates on file mode changes
Handle more cases for file mode changes. Especially make sure that the
following cases are handled correctly.
Case 1)
An entry in the working tree, HEAD tree, and merge tree have
different modes and different content.
Prior Outcome:
Dirty working tree content is replaced and file mode
changes are lost.
New Outcome:
Conflict is generated.
Case 2)
An entry in the index and merge tree have the same content
but different modes but both modes are file type modes.
Prior Outcome:
File mode in working tree is not updated and the working
directory is dirty.
New Outcome:
Index is updated and the working directory is clean.
