Jeff Squyres 0f8ac9223f Refs trac:2023, #2027.
This commit does a bunch of things:

 * Address all remaining code review items from CMR #2023:

   * Defer mmap setup to be lazy; only set it up the first time we
     invoke a collective.  In this way, we don't penalize apps that
     make lots of communicators but don't invoke collectives on them
     (per #2027).
   * Remove the extra assignments of mca_coll_sm_one (fixing a
     convertor count setup that was the real problem).
   * Remove another extra/unnecessary assignment.
   * Increase libevent polling frequency when using the RML to
     bootstrap mmap'ed memory.
   * Fix a minor procs-related memory leak in btl_sm.
 * Commit a datatype fix that George and I discovered along the way to
   fixing the coll sm.
 * Improve error messages when mmap fails, potentially trying to
   de-alloc any allocated memory when that happens.
 * Fix a previously-unnoticed confusion between extent and true_extent
   in coll sm reduce.

[sys call fail]
A system call failed during shared memory initialization that should
not have. It is likely that your MPI job will now either abort or
experience performance degredation.
Local host: %s
System call: %s %s
Error: %s (errno %d)
#
[mmap too small]
Open MPI requested a shared memory segment that was too small to do
anything useful. This is likely an error in Open MPI itself. If you
see this error, you should see if there is an update available for
Open MPI, and if not, contact the Open MPI developers.
Local host: %s
Requested size: %ul
