Ed Maste dc17b1feaa Speed up pmcstat by improving string hash ...

In one case generating callgraph output from a 24MB system-wide sampling
data file took 17.4 seconds on average.  Profiling showed pmcstat
spending a lot of time in strcmp, due to hash collisions.

Replacing the XOR-only hash with FNV-1a reduces the run time for my
test by 40%.
