python - be: Implement IN/OUT parameters.

Log Message:
-----------
Implement IN/OUT parameters. =)

This required that anonymous records be worked in. Currently, there is no typmod
based dictionary to lookup corresponding blessed PyPgTupleDesc's.

Compensate for out parameters in src/function.c input TupleDesc creator(Would
probably be better to have something like this in core ;).

Additionally, don't run an SRF call if the function is not an SRF. This should
probably be the case generally, but...

typ_td is now used to store the blessed record type TupleDesc and for registered
composite type TupleDesc's.

Make test/regress.py take the pg_config(--postgresql) parameter for explicit
version specification.

8.0 support persists.
