[PATCH] Perf-tools create common process_event functions

[PATCH] Perf-tools create common process_event functions

[John Kacur]

This continues the effort to prevent bit-rot in perf-annotate by using
common functions for perf-report and perf-annotate where possible.

This creates the process.[ch] files.
More functions can be added here after - but this is a working step
in the process.
