The OPAL_PROC_ON_* definitions have been changed from values to
flags. This should not cause any problems as these values were already
used as flags throughout the code base. Note, there will be a
difference between localities produced by the new code and the
old. For example, if a machine does not have a level-3 but two cores
share a level-1 or level-2 cache cache the level-3 bit will not be set
in the locality and OPAL_PROC_ON_LOCAL_L3CACHE will return 0. Before
this change it would have returned 1.
In addition the OPAL_PROC_ON_LOCAL_* macros have been simplified.

Looks like in ess_pmi_module.c u32 is being used
for retrieving OPAL_PMIX_LOCAL_SIZE, while s1/s2/cray
pmix components were storing as u16.
This commit fixes this problem.

This commit makes two changes to the tcp btl:
- If a tcp proc does not exist when handling a new connection create
a new proc and use it. The current implementation uses the
opal_proc_by_name() function to get the opal_proc_t then calls
add_procs on all btl modules. It may be sufficient to just call
add_procs until an endpoint is created so this may change somewhat.
- In add_procs add a check for an existing endpoint before creating
one.

This commit adds an opal hash table to keep track of mapping between
process identifiers and ompi_proc_t's. This hash table is used by the
ompi_proc_by_name() function to lookup (in O(1) time) a given
process. This can be used by a BTL or other component to get a
ompi_proc_t when handling an incoming message from an as yet unknown
peer.
Additionally, this commit adds a new MCA variable to control the new
add_procs behavior: mpi_add_procs_cutoff. If the number of ranks in
the process falls below the threshold a ompi_proc_t is created for
every process. If the number of ranks is above the threshold then a
ompi_proc_t is only created for the local rank. The code needed to
generate additional ompi_proc_t's for a communicator is not yet
complete.

This commit updates each non-compliant btl to send the
MCA_BTL_FLAGS_SEND flag in the btl_flags field if send is
supported. This fixes a problem identified after the latest bml/r2
update which excplicitly checks for the send flag.

Add more stubs to reduce likelihood of future
mysterious segfaults if some of the newer pmix
funcs start to get used within ompi.
Add a get_version to return the version of the
Cray PMI library being used, since the Cray PMI
library actually has a function to get that info.
Be more accurate about which functions have a hope
of being implemented using Cray PMI and those which
never will.
