Split plpython.c into smaller pieces This moves the code around from one huge file into hopefully logical and more manageable modules. For the most part, the code itself was not touched, except: PLy_function_handler and PLy_trigger_handler were renamed to PLy_exec_function and PLy_exec_trigger, because they were not actually handlers in the PL handler sense, and it makes the naming more similar to the way PL/pgSQL is organized. The initialization of the procedure caches was separated into a new function init_procedure_caches to keep the hash tables private to plpy_procedures.c. Jan Urbański and Peter Eisentraut

/*
* Include order should be: postgres.h, other postgres headers, plpython.h,
Fix assorted header files that failed to compile standalone. We have a longstanding project convention that all .h files should be includable with no prerequisites other than postgres.h. This is tested/relied-on by cpluspluscheck. However, cpluspluscheck has not historically been applied to most headers outside the src/include tree, with the predictable consequence that some of them don't work. Fix that, usually by adding missing #include dependencies. The change in printf_hack.h might require some explanation: without it, my C++ compiler whines that the function is unused. There's not so many call sites that "inline" is going to cost much, and besides all the callers are in test code that we really don't care about the size of. There's no actual bugs being fixed here, so I see no need to back-patch. Discussion: https://postgr.es/m/b517ec3918d645eb950505eac8dd434e@gaz-is.ru

plpython: Avoid the need to redefine *printf macros Until now we undefined and then redefined a lot of *printf macros due to worries about conflicts with Python.h macro definitions.

plpython: Code cleanup related to removal of Python 2 support. Since 19252e8ec93 we reject Python 2 during build configuration. Now that the dust on the buildfarm has settled, remove Python 2 specific code, including the "Python 2/3 porting layer". The code to detect conflicts between plpython using Python 2 and 3 is not removed, in case somebody creates an out-of-tree version adding back support for Python 2.
