L4Re::Util::Dataspace_svr

Hi again,
I believe the Dataspace_svr dispatch function is missing a case for
L4Re::Dataspace_::Allocate (as declared in
l4/pkg/l4re/include/dataspace-sys.h) -- I receive this opcode and since
there is no handling the result is a return of -L4_ENOSYS (which will
make subsequent processing fail).
As a quick fix the attached patch works but there should probably also
be a hook (virtual function) in the Dataspace_svr class (and maybe some
more sophisticated default processing, not sure).
Thanks,
Daniel
