[petsc-dev] tool to find potential static functions

Hi again,

a first attempt (this time in Python...):

$:PETSC_DIR> python bin/pythonscripts/PetscStaticFunctionCandidates.py

gives you a list of functions only used within a single file in src/ts/*
(making this a script parameter later...)

The parsing certainly needs improvement, but it gives a first idea. Most 
importantly, my interpretation of the problem description
  "find all functions which are only used in a single file"
ignored all the stuff in examples/*, and some of the obvious public 
functions thus get listed as well. I will also fix that, even though 
this drives up execution time for some folders considerably.

Still, the script is definitely better than nothing already at this 
early stage.

Best regards,
