After creating a Transport instance callers should always call
its close() method. Use AutoCloseable to document this idiom
and allow use of try-with-resources.

This should mirror the behavior of `git push --atomic` where the
client asks the server to apply all-or-nothing. Some JGit servers
already support this based on a custom DFS backend. InMemoryRepository
is extended to support atomic push for unit testing purposes.

Local disk server side support inside of JGit is a more complex animal
due to the excessive amount of file locking required to protect every
reference as a loose reference.

When the file <git-dir>/hooks/pre-push exists make sure that is is
executing during a push. The pre-push hook runs during git push, after
the remote refs have been updated but before any objects have been
transferred.

RecievePack already honors fsck settings for safeForWindows and
safeForMacOS.  Allow those same checks to be performed during fetch
through a caller-configurable ObjectChecker.

Default the fetch fsck options to match the current platform, as
it can be reasonably assumed the repository will be accessed here.

Currently, Repository.getAllRefs() and Repository.getTags() silently
ignores an IOException and instead returns an empty map. Repository
is a public API and as such cannot be changed until the next major
revision change. Where possible, update the internal jgit APIs to
use the RefDatabase directly, since it propagates the error.

Setting the walk and other fields to null will result in NPEs when the
user e.g. calls fetch on the connection, but at least the advertised
refs can be read like that without having a local repository.

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.

Use the Java 6 like services approach to find all supported
TransportProtocols within the CLASSPATH and load them all for use.

This allows users to inject additional protocol implementations simply
by putting their JARs on the application CLASSPATH, provided the
protocol author has written the proper services file.

The new TransportProtocol type describes what a particular Transport
implementation wants in order to support a connection.  3rd parties
can now plug into the Transport.open() logic by implementing their
own TransportProtocol and Transport classes, and registering with
Transport.register().

GUI applications can help the user configure a connection by looking
at the supported fields of a particular TransportProtocol type, which
makes the GUI more dynamic and may better support new Transports.

This change is based on http://egit.eclipse.org/r/#change,1652
by David Green. The change adds the concept of a CredentialsProvider
which can be registered for git transports and which is
responsible to return credential-related data like passwords and
usernames. Whenenver the transports detects that an authentication
with certain credentials has to be done it will ask the
CredentialsProvider for this data. Foreseen implementations for
such a Provider may be a EGitCredentialsProvider (caching
credential data entered e.g. in the Clone-Wizzard) or a NetRcProvider
(gathering data out of ~/.netrc file).

Rather than relying on the helpers in RepositoryConfig to get
these objects, obtain them directly through the Config API.
Its only slightly more verbose, but permits us to work with the
base Config class, which is more flexible than the highly file
specific RepositoryConfig.

This is what I really meant to do when I added the section parser
and caching support to Config, we just failed to finish updating
all of the call sites.

On Windows, FS_Win32_Cygwin has been used if a Cygwin Git installation
is present in the PATH. Assuming that the user works with the Cygwin
Git installation may result in unnecessary overhead if he actually
does not.

Applications built on top of jgit may have more knowledge on the
actually used Git client (Cygwin or not) and hence should be able to
configure which FS to use accordingly.

The strings are externalized into the root resource bundles.
The resource bundles are stored under the new "resources" source
folder to get proper maven build.

Strings from tests are, in general, not externalized. Only in
cases where it was necessary to make the test pass the strings
were externalized. This was typically necessary in cases where
e.getMessage() was used in assert and the exception message was
slightly changed due to reuse of the externalized strings.
