submodules

Change-Id: Id37efb4f4dd77f3b8eb5607d15d32adeda3992d4

For each submodule native git allows to configure which modifications to
submodules should be ignored by the status command. It is possible to
ignore "none", "all", "dirty", "untracked" [1]. This configuration is
now supported by IndexDiff. The StatusCommand offers the possibility to
specify this mode.

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.

These appear as descriptions in the index, see here (currently empty):

This was broken in fe1f1b8f8aba60fdd1ad6f0f72e9c9180978cc60, which
preferred the index over the working tree when both were present.

Whenever a call to JGit returns a Repository the caller should make sure
to call close() on it if he doesn't need it anymore. Since instances of
Repository contain e.g. open FileOutputStreams (for pack files)
forgetting to close the repository can lead to resource leaks.

This was the reason why dozens of the JUnit tests failed on Windows
with "Can't delete file ...." errors. 

In LocalDiskRepositoryTestCase.tearDown() we tried to delete the
repositories we used during tests which failed because we had open
FileOutputStreams.

Not only the obvious cases during Clone or Init operations returned
Repositories, but also the new SubModule API created repository
instances. In some places we even forgot to close submodule repositories
in our internal coding.

To see the effects of this fix run the JGit JUnit tests under Windows.
On other platforms it's harder to see because either the leaking
resources don't lead to failing JUnit tests (on Unix you can delete
files with open FileOutputStreams) or the java gc runs differently and
cleans up the resources earlier.

It is not always appropriate to use the .gitmodules file from the
working tree, for example if reading the modules at a specific commit.
And sometimes it is impossible, as in a bare repository.

When using the static factory methods, automatically set up the
appropriate root tree so lazy loading of the config file reads from
the appropriate place. Leave the current behavior of looking in the
working tree as a fallback for the case where walking the index.

We need a way to release the underlying TreeWalk. Also, use this
method to release walks from the static factory methods on error or
when submodules are not found.

A '.git' file in a repository's working tree root is now parsed
as a ref to a folder located elsewhere.  This supports submodules
having their repository location outside of the parent repository's
working directory such as in the parent repository's '.git/modules'
directory.

This adds support to BaseRepositoryBuilder for repositories created
with the '--separate-git-dir' option specified to 'git init'.

Interpret submodule URLs that start with './' or '../' as
relative to either the configured remote for the HEAD branch,
or 'origin', or the parent repository working directory if no
remote URL is configured

Bug: 368536
Change-Id: Id4985824023b75cd45cd64a4dd9d421166391e10

Adds the following commands:
    - Add
    - Init
    - Status
    - Sync
    - Update

This also updates AddCommand so that file patterns added that
are submodules can be staged in the index.
