From: Pontus Jaensson <= ;pontusja@axis.com>

This patch consists of a Submodule class which inherits from and extends th= e FetchMethod-class
for retrieving, initializing and updating a submodule directory. The main r= eason for implementing
it is to make it possible to track the version of a packet with git instead= of just a recipe.

The submodule fetcher is used by using the following syntax in the SRC_URI = field in the recipe:
SRC_URI =3D submodule://<PATH TO TOP LEVEL DIRECTORY>;localpath=3D<= ;NAME OF THE WANTED SUBMODULE>.
Where the submodule-keyword is necessary to use in order to call this speci= fic fetcher.

In the download-method the URI is then parsed and the relevant parts from i= t are extracted and
used to find information about the module in the .gitmodules-file in the to= p level git directory.
The final thing that happens in the download-method is that git submodule i= nit & git submodule
update are called and executed at the right location for the specified subm= odule.

In the unpack-method the empty directory, that is being created during the = process but contains no
information, is removed and replaced with a symlink to the directory that c= ontains the actual
source code.

The code has been tested and so far it seems to work fine.
