JGit 3.0: move internal classes into an internal subpackage
This breaks all existing callers once. Applications are not supposed
to build against the internal storage API unless they can accept API
churn and make necessary updates as versions change.

Update the revert command and things relating to revert
Cherry-pick has been fixed, but even though revert does
basically the same thing, the fixes were not carried over here.
- Recognize the revert-states, analogous to the cherry picking states
- Make reset handle a revert-in-progress
- Update REVERT_HEAD and MERGE_MSG when revert fails due to conflicts
- Clear revert state on commit and reset
- Format the message similarily to how cherry-pick does. This is
not exactly how C Git does it.
The interface is still not the same as for cherry-picking.

A few classes such as Constanrs are marked with @SuppressWarnings, as are
toString() methods with many liternal, but otherwise $NLS-n$ is used for
string containing text that should not be translated. A few literals may
fall into the gray zone, but mostly I've tried to only tag the obvious
ones.

Fix resolving expression with ~ and ^ than extends beyond history
resolve("foo~X") where X is greater than the distance from foo to the

behavior.
Also add an analogous test for foo^X where X is greater than the

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".

Deprecate GitIndex more by using only DirCache internally.
This includes merging ReadTreeTest into DirCacheCheckoutTest and
converting IndexDiffTest to use DirCache only. The GitIndex specific
T0007GitIndex test remains.

Since we replaced GitIndex by DirCache JGit didn't fire
IndexChangedEvents anymore. For EGit this still worked with a high
latency since its RepositoryChangeScanner which is scheduled to
run each 10 seconds fires the event in case the index changes.
This scanner is meant to detect index changes induced by a different
process e.g. by calling "git add" from native git.
When the index is changed from within the same process we should fire
the event synchronously. Compare the index checksum on write to index
checksum when index was read earlier to determine if index really
changed. Use IndexChangedListener interface to keep DirCache decoupled
from Repository.

Add handling of CHERRY_PICK_HEAD file in .git (similar to MERGE_HEAD),
which is written in case of a conflicting cherry-pick merge.
It is used so that Repository.getRepositoryState can return the new
states CHERRY_PICKING and CHERRY_PICKING_RESOLVED. These states, as well
as CHERRY_PICK_HEAD can be used in EGit to properly show the merge tool.
Also, in case of a conflict, MERGE_MSG is written with the original
commit message and a "Conflicts" section appended. This way, the
cherry-picked message is not lost and can later be re-used in the commit
dialog.

sibilings for mapCommit() and mapTag() were already removed from the
main Repository API.
Remove mapTree(). Application callers who only need the tree's name
can use resolve("^{tree}") syntax to resolve to the tree ObjectId, or
fail if the input is not a tree.
Applications that want to read a tree should use DirCache or TreeWalk.

resolve(): Fix wrong parsing of branch "foo-gbed2-dev"
When parsing a string such as "foo-gbed2" resolve() was assuming the
suffix was from git describe output. This lead to JGit trying to find
the completion for the object abbreviation "bed2", rather than using
the current value of the reference. If there was only one such object
in the repository, JGit might actually use the wrong value here, as
resolve() would return the completion of the abbreviation "bed2"
rather than the current value of the reference "refs/heads/foo-gbed2".
Move the parsing of git describe abbreviations out of the operator
portion of the resolve() method and into the simple portion that is
supposed to handle only object ids or reference names, and only do the
describe parsing after all other approaches have already failed to
provide a resolution.
Add new unit tests to verify the behavior is as expected by users.

ObjectReader implementations are now responsible for creating the
unique abbreviation of an ObjectId, or for resolving an abbreviation
back to its full form. In this latter case the reader can offer up
multiple candidates to the caller, who may be able to disambiguate
them based on context.
Repository.resolve() doesn't take multiple candidates into account
right now, but it could in the future by looking for a remaining
^0 or ^{commit} suffix and take an expansion if there is only one
commit that matches the input abbreviation. It could also use
the distance from an annotated tag to resolve "tag-NNN-gcommit"
style strings that are often output by `git describe`.
