Initial implementation for adding a thread to the infiniband plugin in

INITIAL code to change acctg_freq from a uint16_t to a char *
code to make the uint16_t to char * work correctly
Handle timers differently to give us the delta_t without having to call

More missed acctg-freq's
Remove drift from timer thread
Remove bad locks
