metadata changes:
- log pmc sample rate with pmcallocate
- log proc flags with thread / process logging
to identify user vs kernel threads
fixes:
- use log cpuid to translate event id to event name
Implement rudimentary summary command to track sample
counts by thread and process name within a pmc log.
