This commit removes the --with-mpi-thread-multiple option and forces
MPI_THREAD_MULTIPLE support. This cleans up an abstration violation
in opal where OMPI_ENABLE_THREAD_MULTIPLE determines whether the
opal_using_threads is meaningful. To reduce the performance hit on
MPI_THREAD_SINGLE programs an OPAL_UNLIKELY is used for the
check on opal_using_threads in OPAL_THREAD_* macros.
This commit does not clean up the arguments to the various functions
that take whether muti-threading support is enabled. That should be
done at a later time.

This commit allows to control output during abnormal oshmem/ompi application
termination.
Fixed issue in backtrace output. HAVE_BACKTRACE was never set so user was limited
in control of this variable.
Two related mca variables are moved to opal layer. Corresponding aliases are
added for ompi and oshmem.
Some MXM tls such as self, shm can comlete requests immediately.
Make sure that opal_progress() is called before before request
is completed.
fix ud_only logic when hw rdma channel is using ud and main
transport is rc or dc.
when profiling is built.
This prevents oshmem subroutines from being wrapped twice by third
party tools (e.g. once in oshmem and once in MPI)
see discussion starting at http://www.open-mpi.org/community/lists/devel/2015/08/17842.php
Thanks to Bert Wesarg for bringing this to our attention
ompi has new mpi_add_procs_cutoff argument that can control
creation of ompi_proc_t but We should be confident that all
ompi_proc_t object exists during oshmem_group_all creation.
Probably it could be done in more flexible way later.

Most functionality of oshmem_proc duplicates ompi_proc. In addition
to that, Current logic does not allow to do oshmem initialization
w/o ompi startup.
So this refactoring allows to avoid code duplication, decrease used
memory and make oshmem support easier.
Now oshmem_proc is transparent ompi_proc structure, that can be
extended by oshmem specific data.

Any buffer given to opal_dss.load becomes the responsibility of the
opal_buffer_t object. It will be freed automatically if either the
opal_buffer_t is released or opal_dss.load is called again on the
buffer. opal_dss.unload will not prevent this unless no unpacking
takes place between the .load and .unload calls.

Bring Slurm PMI-1 component online
Bring the s2 component online
Little cleanup - let the various PMIx modules set the process name during init, and then just raise it up to the ORTE level. Required as the different PMI environments all pass the jobid in different ways.
Bring the OMPI pubsub/pmi component online
Get comm_spawn working again
Ensure we always provide a cpuset, even if it is NULL
pmix/cray: adjust cray pmix component for pmix
Make changes so cray pmix can work within the integrated
ompi/pmix framework.
Bring singletons back online. Implement the comm_spawn operation using pmix - not tested yet
Cleanup comm_spawn - procs now starting, error in connect_accept
Complete integration
These man pages to OpenSHMEM API are received from openshmem.org
and ported with minimum modifications.

* do not add -I/.../include/fca -I /.../include/fca_core to CPPFLAGS
* allow configure --with-fca
* search fca libs in both DIR/lib and DIR/lib64
* fix the description of the --with-fca option
only define the unique fortran symbol depending on
- CAPS
- PLAIN
- SINGLE_UNDERSCORE
- DOUBLE_UNDERSCORE
and bind the f08 symbol to the uniquely defined C symbol.
Use real data structures to make the code simpler.

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).

Turns out that this is just copy-n-pasted code from OMPI. To be
clear: there's no need for the oshmem layer to instantiate sentinels
like mpi_fortran_bottom.
Thanks @jsquyres for pointing this.
This commit adds support for project_framework_component_* parameter
matching. This is the first step in allowing the same framework name
in multiple projects. This change also bumps the MCA component version
to 2.1.0.
All master frameworks have been updated to use the new component
versioning macro. An mca.h has been added to each project to add a
project specific versioning macro of the form
PROJECT_MCA_VERSION_2_1_0.

Noe that this commit removes option:lt_dladvise from the various
"info" tools output. This technically breaks our CLI "ABI" because
we're not deprecating it / replacing it with an alias to some other
"into" tool output.
Although the dl/libltdl component contains an "have_lt_dladvise" MCA
var that contains the same information, the "option:lt_dladvise"
output from the various "info" tools is *not* an MCA var, and
therefore we can't alias it. So it just has to die.
In order to have an effect, ibv_fork_init should be called in the
beginning of the verbs initialization flow - before the calls to the
ibv_create_qp and ibv_create_cq verbs.
These functions are called from the oob/ud code and by the time the
other verbs components (btl openib, pml yalla, ...) call ibv_fork_init,
it's too late. This commit forces the call to ibv_fork_init (if it's
requested) right at the beginning of all the components that are using
verbs.
(ibv_fork_init() can be safely called multiple times)
This commit also removes the btl_openib_want_fork_support mca parameter
and adds a new mca parameter instead - opal_verbs_want_fork_support.
Through this new parameter, fork support may be requested for ALL
components.
The default value for this parameter is set to 1.
Before this commit the btl_openib_want_fork_support parameter didn't
provide fork support for the openib btl if its value was set to 1.
(because when openib called ibv_fork_init, it was already after the
calls to ibv_create_* in oob/ud and thereofre it failed).
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 ())
