536c279529 adding most of the required functionality for handling MPI-1 and most of MPI-2 communicator functions (except dynamic process management). The cid are currently not yet calculated properly, although the functions are checked in. 
Still to do:
- make the CID allocation routine thread safe
- add the ACK in lam_comm_free
- fix a bug in lam_comm_split for inter-communicators ( in this
  case we can not have allgather_intra and allgather_inter at the
  same time at this communicators, that's however what
  the current implemention assumes).

784693826a add the grp_ok_to_free flag indicating if it is ok to actually 
free the group.  By default this is set to true, with special
code setting this to false for the groups associated with
COMM_NULL, COMM_SELF, and COMM_WORLD.  Also, moved the reference
count decrement on the procs to the group destructor.
