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.

The checkoutPaths body is split into two implementations, depending on
whether we are checking out the index or a branch. This improves
readability, as in the index case we now also need to have access to
DirCacheIterator.

Without this check, the checkout was done but the result was a "both
deleted" status when inspecting it with C Git.

Found this while working on bug 390147.

This change makes CheckoutCommand pass the list of modified files
through the OK result, enabling outside world to react in a smaller
scope (for example refresh only resources containing the modified
files).

An example where this is necessary is when a whole directory was deleted
and checkout is used to restore a file which was in that directory.

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.

Checkout command should throw o.e.j.api.errors.CheckoutConflictException
which is a GitAPIException not o.e.j.errors.CheckoutConflictException.
PullCommand should rethrow the API exception as a JGitInternalException.

The checkout command was producing an inconsistent state of the index
which even confuses native git. The content sha1 of the touched index
entries was updated, but the length and the filemode was not updated.
Later in coding the index entries got automatically corrected (through
Dircache.checkoutEntry()) but the correction was after persisting the
index to disk. So, the correction was lost and we ended up with an index
where length and sha1 don't fit together.
A similar problem is fixed with "lastModified" of DircacheEntry. When
checking out a path without specifying an explicit commit (you want to
checkout what's in the index) the index was not updated regarding
lastModified. Readers of the index will think the checked-out
file is dirty because the file has a younger lastmodified then what's
in the index.

We were diverging from the reference implementation. Always use the
ref we checkout to as the to-branch the reflog and avoid the
refs/heads both in the from-name and to-name.

As discussed in

we should use paths relative the working directory instead of Files to
notify the caller about conflicts and nondeleted files.

names properly; it must detach HEAD if such a name is encountered (for

This is needed by callers to determine checkout conflicts and
possible files that were not deleted during the checkout so that they
can present the end user with a better Exception description and retry
to delete the undeleted files later, respectively.

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.
