Tags can be un-annotated whereby there is no RevTag object, only
a ref pointing to the tagged object.

Bug: 360650
Change-Id: I06309c45c0a896fe2a0a874700febf78c9fb87e8

Creation of a branch X from an annotated tag, as the starting point,
resulted into .git/refs/heads/X containing the ID of the annotated tag
instead of the ID of the tagged commit.

This fix peels the tag ref before using it as the starting point for
the newly created branch.

If remote branches are present they can not be added
to the RefMap from the local branches - the two RefMaps
have a different value of 'prefix' and consequently an
IllegalArgumentException is thrown.

Eclipse has some problem re-running single JUnit tests if
the tests are in Junit 3 format, but the JUnit 4 launcher
is used. This was quite unnecessary and the move was not
completed. We still have no JUnit4 test.

This completes the extermination of JUnit3. Most of the
work was global searce/replace using regular expression,
followed by numerous invocarions of quick-fix and organize
imports and verification that we had the same number of
tests before and after.

- Annotations were introduced.
- All references to JUnit3 classes removed
- Half-good replacement for getting the test name. This was
  needed to make the TestRngs work. The initialization of
  TestRngs was also made lazily since we can not longer find
  out the test name in runtime in the @Before methods.
- Renamed test classes to end with Test, with the exception
  of TestTranslateBundle, which fails from Maven
- Moved JGitTestUtil to the junit support bundle

It wrongly uses the full name of the branch to remove the
configuration entries but must use the shortened one.

When creating a branch with CreateBranchCommand.call() without
specifying an explicit startPoint HEAD should be used as startPoint.
There was a bug leading to an NPE in such a case.

We wanted to wrap all LowLevel JGit excpetions into a
JGitInternalException so that users of this high-level interface
don't have to explicitly catch all of them. This
was forgotten on BranchCreateCommand.call() and I added
it.

The need for branching becomes more pressing with pull
support: we need to make sure the upstream configuration entries
are written correctly when creating and renaming branches
(and of course are cleaned up when deleting them).
This adds support for listing, adding, deleting and renaming
branches including the more common options.
