000f9eed4d opal: add types for atomic variables
This commit updates the entire codebase to use specific opal types for
all atomic variables. This is a change from the prior atomic support
which required the use of the volatile keyword. This is the first step
towards implementing support for C11 atomics as that interface
requires the use of types declared with the _Atomic keyword.

1282e98a01 opal/asm: rename existing arithmetic atomic functions
This commit renames the arithmetic atomic operations in opal to
indicate that they return the new value not the old value. This naming
differentiates these routines from new functions that return the old
value.

d7ebcca93f Add volatile to the pointer in the list_item structure. (#3468)
This change has the side effect of improving the performance of all
atomic data structures (in addition to making the code crrect under a
certain interpretation of the volatile usage).
This commit fixes #3450.

a7045352e2 Modify the OPAL_LIST_RELEASE and OPAL_LIST_DESTRUCT macros to release the objects only when the list object is refcounted down to 1, which will then reach zero when destructed/released at the end of the macro

Revert "OPAL: drop dead with core on bad flow. rarely happens with helloworld on large scale."

This reverts commit 86f1d5af3e.

Will be reconsidered via RFC as it represents a significant change in behavior

60485ff95f This is a very large change to rename several #define values from
OMPI_* to OPAL_*.  This allows opal layer to be used more independent
from the whole of ompi.

fd28b392bf - An intrusive commit yet again (sorry): with the separation we
get bitten by header depending on having already included
   the corresponding [opal|orte|ompi]_config.h header.
   When separating, things like [OPAL|ORTE|OMPI]_DECLSPEC
   are missed.

   Script to add the corresponding header in front of all following
   (taking care of possible #ifdef HAVE_...)

 - Including some minor cleanups to
   - ompi/group/group.h -- include _after_ #ifndef OMPI_GROUP_H
   - ompi/mca/btl/btl.h -- nclude _after_ #ifndef MCA_BTL_H
   - ompi/mca/crcp/bkmrk/crcp_bkmrk_btl.c -- still no need for
     orte/util/output.h
   - ompi/mca/pml/dr/pml_dr_recvreq.c -- no need for mpool.h
   - ompi/mca/btl/btl.h -- reorder to fit
   - ompi/mca/bml/bml.h -- reorder to fit
   - ompi/runtime/ompi_mpi_finalize.c -- reorder to fit
   - ompi/request/request.h -- additionally need ompi/constants.h

 - Tested on linux/x86-64

cc3805d861 Because opal_list is used in the C++ bindings, where not having
"const" in the argument creates [correct] warnings (because __FILE__
is a (const char*)).  Plus, opal_object.cls_init_file_name is already
(const char*).

5e280cda19 Latest and greatest. Now OPAL is ready for the Windows prime-time.
The same treatement will happens on all sub-projects. The .h files
have to be C++ compatibles and all symbols with an external visibility
have to get the {PROJECT}_DECLSPEC in front of the prototype.

6afa4c6c64 Windows friendly version. We have to split the OMPI_DECLSPEC in at least 3
different macros, one for each project. Therefore, now we have OPAL_DECLSPEC,
ORTE_DECLSPEC and OMPI_DECLSPEC. Please use them based on the sub-project.

a43eb4b43e It's not about how much memory we use, but about how we use it.
Keeping the cache misses as low as possible is always a good approach.
The opal_list_t is widely used, it should be a highly optimized class.
The same functionality can be reached with one one sentinel instead
of 2 currently used.
I don't have anything against the STL version, but so far nothing can
compare with the Knuth algorithm. I replace the current implementation
with a modified version of the Knuth algorithm (the one described in
The Art of Computer Programming). As expected, the latency went down.

566a050c23 Next step in the project split, mainly source code re-arranging
- move files out of toplevel include/ and etc/, moving it into the
    sub-projects
  - rather than including config headers with <project>/include, 
    have them as <project>
  - require all headers to be included with a project prefix, with
    the exception of the config headers ({opal,orte,ompi}_config.h
    mpi.h, and mpif.h)
