MPE: fine-grained logging support

Description (last modified by balaji)


Current MPE logging is based on a giant lock.
This is OK as long as MPI implementation has a global-mutex.
As MPICH2 is moving toward fine grained lock, MPE
logging needs to move to a more/less lock-free approach.
i.e. one logging buffer per thread.  The logfile merging
will need to be updated as well.
