Add support for clock_gettime on Linux. Allow the user to
request a monotonic timer via MCA parameters.
Various cleanups.
Update copyrights and mark ia32 timers as non-monotonic.
ess/alps: add initial alps ess component

Note this alps ess component has nothing to do
with the old CNOS alps component used on
Cray Seastar/Portals3 (Cray XT) systems.

To work properly, changes need to be made to the
open method of the ess/pmi component to keep it
from selecting, and thus initializing, the opal/pmix/cray
component.
orte/common/alps: add an alps common lib to orte

Add an alps common lib to orte.  Add a function
to determine whether or not a process is in a
PAGG container.

Note: we need a better naming convention for
common libs, since right now they use a "flat"
naming convention.
odls/alps: make sure PMI env. variables set up

Add call to orte_odls_alps_get_rdma_creds in the
local proc launch step to obtain the Cray Rdma
credentials from the apshepherd, and to set
the PMI env. variables expected by uGNI BTL, etc.
alps configury changes

Clean up the orte_check_alps.m4.  There was a little of
unnecesary stuff for handling cle 5, since it wasn't actually
doing the right thing, which would be to use pkg-config to
find dependencies both for dynamic and static linking.

Decouple the searching for alps libs, etc. from cray pmi.

Switch the alps ess  and alps odls components' config files
to use the ALPS m4 macro.

alps configury fixes

Improve a check for detecting CLE release.
Improve an error message.
orte/mca/common: add missing Makefile.am
orte/mca/common/alps: fix configure file

Fix configure file for alps to actually check for
alps being available.

Also include stdio.h explicitly in common_alps.c
pmix/cray: remove finalize call from comp close

The finalize call in component close method is
no longer being matched by an equivalent init call,
so remove this call in the close method.

opal_timer_require_monotinic: change to bool / level 5
Fix singleton comm-spawn, yet again. The new grpcomm collectives require a complete knowledge of every active proc in the system in case they participate in a collective. So ensure we pass the required job info when we spawn new daemons, and construct the necessary connections to allow grpcomm to operate.
Fix the clock_gettime monotonic timer. Thanks to Gilles for the
first sketch of the patch.
debuggers: update warning messages when types not found

Fixes #302.
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.
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.
