1335 update for compression and off_t type

1329 add pid/pgid to RUN_RUSAGE for readstream.py

change build to be platform agnostic

SWIG, run by build_ext, generates a shared object file and a
python library.  The latter needs to be generated before build_py
is run so that build_py finds it.  Unfortunately the default in
setuptools is to run build_py before build_ext.  The solution
is to override the build class so that the build order can be
changed.

With this change, "pip install" works better, including when
lsf-python-api is a dependency of another module.
