profiling squid-3

I've started profiling squid-3 in preparation for the feature-complete
release.

The test rig:

* p4 2.6GHz - Dapper Ubuntu (Linux-2.6.15), cpu/ram info in perf output
* no disk caching; just memory caching for now
* Polygraph server - Athlon 1800XP +, 1gb RAM, FreeBSD 6.1, datacomm-1, 300req/sec
* served ~ million requests through it.

Results:

Summary:

* Lots of pressure on the memory allocator, http parsing code.
* Loads of room for improvement, as we all know :)

I'll get a gprof trace next to find out where the pressure is coming
from.
