Fix NullPointer when pulling from a deleted local branch
A checked Exception is thrown instead.
The reason for throwing an Exception is that the state of the
repository is inconsistent in this case: There is a merge
configuration containing a non-existing local branch. Ideally the
deletion of a local branch should also delete the corresponding
merge configuration.

PullCommand: use default remote instead of throwing Exception
When pulling into a local branch that has no upstream configuration,
pull should try to used the default remote ("origin") instead of
throwing an Exception.

RebaseCommand: detect and handle fast-forward properly
This bug was hidden by an incomplete test: the current Rebase
implementation using the "git rebase -i" pattern does not work
correctly if fast-forwarding is involved. The reason for this is that
the log command does not return any commits in this case.
In addition, a check for already merged commits was introduced to
avoid spurious conflicts.

If HEAD exists but points to an not-existing branch the merge
command should silently create the missing branch and check
it out. This happens if you pull into freshly initalized repo.
HEAD points to refs/heads/master but refs/heads/master doesn't
exist. If you know merge a commit X into HEAD then the branch
master should be created (pointing to X) the working tree should
be updated to reflect X. That is achieved by checkout with one
tree only (HEAD is missing).
A test for this functionality will come the the next proposal
in PullCommandTest.

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.
There is a space missing between <from> and "to" in the reflog
message produced by the CheckoutCommand, which is of the form
moving from <from> to <to>

This is almost reverted cherry-pick, and the implementation is
almost identical. It orders the input to merge differently to get
the effect and produces a different commit message with the

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

Each time getConfig() is called on FileRepository, it checks the
last modified time of both ~/.gitconfig and $GIT_DIR?config. If
$GIT_DIR/config appears to have been modified, it is read back in
from disk and the current config is wiped out.
When mutating a configuration file, this may cause in-memory edits
to disappear. To avoid that callers need to avoid calling getConfig
until after the configuration has been saved to disk.
Unfortunately the API is still horribly broken. Configuration should
be modified only while a lock is held on the configuration file, very
similar to the way a ref is updated via its locking protocol. But our
existing API is really broken for that so we'll have to defer cleaning
up the edit path for a future change.

Rebase: abort on unknown/unsupported command in git-rebase-todo
This is needed to ensure interoperability with the command line: if
the git-rebase-todo file was created manually (by git rebase -i in the
command line), and any commands other than pick are used (reword,
edit, fixup, squash) JGit must abort as it does not understand these
commands yet.
The same is true if an unknown command is found (e.g. due to a typo);
this is the same behavior as shown by the command line.

For --continue, the Rebase command asserts that there are no unmerged
paths in the current repository. Then it checks if a commit is needed.
If yes, the commit message and author are taken from the author_script
and message files, respectively, and a commit is performed before the
next step is applied.
For --skip, the workspace is reset to the current HEAD before applying
the next step.
Includes some tests and a refactoring that extracts Strings in the
code into constants.

Its confusing that a new TreeWalk() needs to have reset() invoked
on it before addTree(). This is a historical accident caused by
how TreeWalk was abused within ObjectWalk.
Drop the initial empty tree from the TreeWalk and thus remove a
number of pointless reset() operations from unit tests and some of
the internal JGit code.
Existing application code which is still calling reset() will simply
be incurring a few unnecessary field assignments, but they should
consider cleaning up their code in the future.
