PGI was failing to build this test due to the {} initializers of some
of the global variables. The initializers were added to remove common
symbols from the test repository. This commit removes the initializers
and makes the variables static which should fix both the compile issue
and avoid the common symbols.
This commit additionally removes the check for
OPAL_ENABLE_MULTI_THREADS since Open MPI requires thread support.

This commit does two things. It removes checks for C99 required
headers (stdlib.h, string.h, signal.h, etc). Additionally it removes
definitions for required C99 types (intptr_t, int64_t, int32_t, etc).

This test needs to be tweaked to not use MPI_Init (and only use
opal_init_util(), per #568). @ggouaillardet can't get to this until
next week sometime, so we're just temporarily disabling it for now.
Fixes#568
Use of the old ompi_free_list_t and ompi_free_list_item_t is
deprecated. These classes will be removed in a future commit.
This commit updates the entire code base to use opal_free_list_t and
opal_free_list_item_t.
Notes:
OMPI_FREE_LIST_*_MT -> opal_free_list_* (uses opal_using_threads ())

Many of these tests were failing due to opal_init() failing in some
cases (because the opal shmem framework needs installed components, so
"make distcheck" would fail these tests because the opal shmem
components were not installed). However, all of these tests seem to
be fine with opal_init_util() -- so let's re-enable these tests.
Now that "make check" siphons off stdout/stderr to logfiles, it's ok
to have output by default from tests. This test fails often enough
that it's useful to see the diagnostic output.
This commit adds a new class: opal_fifo.h. The new class has atomic, non-atomic,
and opal_using_threads() conditoned routines. It should be used when first-in
first-out is required and should perform much better than using locks and an
opal_list_t. Like with opal_lifo_t there are two versions of the atomic
implementation: 128-bit compare-and-swap, and spin-locked. More implementations
can be added later (LL/SC comes to mind).
This commit also adds a unit test for the opal_fifo_t class. This test verifies
the fifo implementation when using multiple threads.
- 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.
We recognize that this means other users of OPAL will need to "wrap" the opal_process_name_t if they desire to abstract it in some fashion. This is regrettable, and we are looking at possible alternatives that might mitigate that requirement. Meantime, however, we have to put the needs of the OMPI community first, and are taking this step to restore hetero and SPARC support.
the OPAL and ORTE libraries. This is required by projects such as ORCM
that have their own ORTE and OPAL libraries in order to avoid library
confusion. By renaming their version of the libraries, the OMPI
applications can correctly dynamically load the correct one for their
build."
This reverts commit 63f619f871.
