[Patches] getpath patch

[M.-A. Lemburg]

Patch Set Contents:
-------------------

Modules/getpath.c:

Landmark changed to os.py.

Setting PYTHONHOME now unconditionally sets sys.prefix
(and sys.exec_prefix). No further checks are done whether the
standard lib can be found in that location or not. This is in
sync with the PC subdir getpath implementations.

PC/getpathp.c:

Landmark changed to os.py.

PC/os2vacpp/getpathp.c:

Landmark changed to os.py.

Note: Python will dump core if it cannot find the exceptions module. Perhaps we should add a builtin _exceptions module
(basically a frozen exceptions.py) which is then used as
fallback solution ?!
