20c6eb5237 Rename opal_atomic_lifo_t to opal_lifo_t and improve interface 
- Rename opal_atomic_lifo_t to opal_lifo_t to reflect both atomic and
   non-atomic usage. Added new routines (opal_lifo_*_st) for non-atomic
   usage as well as routines conditioned off opal_using_threads(). The
   atomic versions are always thread safe and the non-atomic are always
   not thread safe.

 - Add a new atomic lifo implementation that makes use of 128-bit
   compare-and-swap. The new implementation should scale better with
   larger numbers of threads.

 - Add threading unit test for opal_lifo_t.

250f749602 Fix return type of opal_atomic_cmpset_128. 
The return type will be opal_int128_t after the fetching atomics
changes but for now it is int.

b1632dfb3c Define opal_int128_t type if a 128-bit integer is available. 
There currently is no standard support for 128-bit integer types. Any use
of the __int128 and int128_t types can lead to warnings from the compiler
when using -Wpedantic. Additionally, some compilers may support __int128
and other may support int128_t. This commit addresses both issues by
defining opal_int128_t if there is a supported 128-bit type. In the
case of GCC a pragma has been added to suppress warnings about __int128
not being a standard C type.

b2b58b31a2 Add support for 128-bit compare and swap on x86_64 when available. 
A 128-bit compare-and-swap will enable a better atomic lifo implementation
that uses the pointer + counter method to avoid ABA issues. This commit
adds configury to check for the instruction (cmpxchg16b) and adds an
implementation that uses the __int128 type available in C99.

c0c680bccb Portals4 BTL: Do not disqualify if a peer does not put Portals4 BTL modex info 
If OPAL_MODEX_RECV() returns OPAL_ERR_NOT_FOUND, the peer didn't
send any Portals4 BTL info.  This is not a fatal error.  Instead of
disqualifying the Portals4 BTL just ignore that peer.

@jsquyres reported this in #194.

c75dccede1 pmix/cray: remove finalize call from comp close

3f9d9ae8b6 Provide tighter LSF integration by correctly handling scenarios where the user has asked LSF to assign bindings. Fix a couple of typos in lex parser definitions. Tell hostfile parser to ignore binding designations in hostfiles. Add an attribute to indicate that cpusets were provided as physical cpu ids. 
Once validated, a version of this will be backported to the v1.8.4 release.

dee243c58d ompi_proc_finalize has an interesting side effect. A proc is 
inserted in the ompi_proc_list as soon as it is created and it
is removed only upon the call to the destructor. In ompi_proc_finalize
we loop over all procs in ompi_proc_finalize and release them once.
However, as a proc is not removed from this list right away, we
decrease the ref count for each proc until it reach zero and the
proc is finally removed. Thus, we cannot clean the BML/BTL after
the call the ompi_proc_finalize.
A quick fix is to delay the call to ompi_proc_finalize until all
other frameworks have been finalized, and then the behavior
depicted above will give the expected outcome.
