The provider and plugin are now 'pure' modules and code shared between them
is in the new shared library libqgisgrass.
This eliminates the libtool warning that linking grassplugin against
libgrassprovider is not portable.
libgrassprovider has also been renamed to grassprovider since it no longer
tries to be a combination provider and shared library (which only worked
on some platforms).
