python: Enable out-of-tree build of pyme bindings.
* lang/python/MANIFEST.in: Update manifest template. * lang/python/Makefile.am: Copy more files, move generation of files to Python build script, add 'sdist' target to build a Python source distribution. * lang/python/gpgme-h-clean.py: Add code to build 'errors.i'. * lang/python/setup.py.in: Generate files, enable out-of-tree builds.
