[perfmon2] Static code checking of libpfm

[William C. <wc...@re...>]

Hi,

I decided to run libpfm from the git repository through the Coverity static code check. I was already running Coverity on PAPI for its upcoming release, and figured it would be easy to do for libpfm also.  Attached are the Coverity results for libpfm in the git repository.

There doesn't appear to be any problems in the library code itself; most of the errors are in the examples and perf_examples. There are a few resource leaks, uninitizaled values, and unused values in the SWIG generated python/src/perfmon_int_wrap.c code.
