Summary: Patch to enable profiling of C functions called from python

Initial Comment:
This patch enables the profiling of C extension functions (and 
builtins) called via the CALL_FUNCTION opcode.  This also includes 
a modification to lib/profile.py to handle the new call type.  On my 
Powerbook 12" 867Mhz it incurs a 0.5% performance hit in the 
interpreter when profiling is not enabled.

Note: this patch is fully backwards with profiler use - the data file is not 
changed in any way.  Also, any 3rd party profilers which would handle 
unknown event types will still continue to work (the standard python 
profiler isn't one of those, so the patch includes a fix for that as well).
