New Revision: 16422

Added:
   pypy/dist/pypy/module/errno/
   pypy/dist/pypy/module/errno/__init__.py
   pypy/dist/pypy/module/errno/interp_errno.py
   pypy/dist/pypy/module/errno/test/
   pypy/dist/pypy/module/errno/test/test_errno.py
Modified:
   pypy/dist/pypy/interpreter/baseobjspace.py
Log:
implemented errno module: very easy because it just contains constants that I
steal from the underlying python implementation. not tested with translation
:-(
