Functioning instance domains for the pcp.pmda python module
This is the last (for now) piece of the PMDA python wrapping
puzzle. The python variant of the simple PMDA now operates
correctly for all of the different PDU variants. Yippee!
Particularly problematic were the pmdaCache instance domains
as there is a bit of a conflict between python insisting on
maintaining type information, and the (void*) parameters we
use in the C API so that PMDAs can store whatever they like.
This is solved using ctypes, with the side-effect that only
ctypes values can be used with pmdaCache indoms.
Other issues resolved include: ensure the instance callback
declaration in python PMDAs matches the C calling convention
(must declare the passed-in indom serial), big improvements
in the python stacktrace logging when exceptions thrown, and
correct the argtypes declarations for a couple of the cache
interface routines from libpcp_pmda (void** vs void*).

Update the pmdasimple sample code to clarify the fetch callback
Also removes an opportunity to use an uninitialised times() list,
which results in an exception and associated badness.

Basic fetch callback methods are now working in python PMDA module
Fixes up the way the tuple returned from the fetch callback is parsed
back in the C code (before interfacing to libpcp_pmda), adds numerous
additional checks and diagnostics to the python return values / error
code, and removes some leftover debug code from earlier commits.

Further work on python pcp.pmda interface modules
Metric namespace refresh now correctly iterates the names
dictionary and populates the C namespace structures. The
short and long help text PDU handling is now also done.
