Log Message:
-----------
Various cosmetic code cleanup for PL/Python:
- use "bool" rather than "int" for boolean variables
- use "PLy_malloc" rather than "malloc" in two places
- define "PLy_strdup", and use it rather than malloc() + strcpy() in
two places (which should have been memcpy(), anyway).
- remove a bunch of redundant parentheses from expressions that do not
need the parentheses for code clarity
