[issue2218] Enhanced hotshot profiler with high-resolution timer

[Jean Brouwers]

New submission from Jean Brouwers:

The _hotshot module uses the gettimeofday function to profile the run 
time.

I enhanced the hotshot module in Python 2.5.2 to use a high resolution 
timer where available (RDTSC on x86/_64, MFTB/U on PowerPC and gethrtime 
on Solaris).

The improved hotshot module has been tested on 32-bit MacOS X 10.4.11 
Tiger (Intel) and 10.3.9 Panther (PPC), on 64-bit RHEL 3u7 (Opteron) and 
on 64-bit Solaris 10.

The 3 modified files are Modules/_hotshot.c, Lib/hotshot/log.py and 
Lib/hotshot/stats.py are attached.
