It was decided some time ago that there is no benefit to using any
per-peer receive queues on infiniband. At the time we decided not to
change the default but that objection has been dropped. This commit
changes the 128 message queue to use SRQ instead of PP. This has no
impact on iWarp which sets the default in a different way.

When PtlMDBind was removed, the result check was left in which
causes intermittent failures depending on the junk value found in
the 'ret' variable. The commit removes the result check.
Rename the pmix1xx component to pmix111 so it reflects the actual release it includes
Resolve the problem of PMIx being passed a bogus --with-platform argument when configuring the PMIx tarball code. There is no reason we should be passing --with-platform arguments to any internal subdirectory, so just leave that out when constructing the opal_subdir_args variable.
Update the PMIx code and continue attempting to debug direct modex
Fix a problem in the ORTE PMIx server - there was an early intent to optimize the direct modex by fetching data for all procs from the target job on the remote node, instead of fetching the data one proc at a time. However, this was never completely implemented, and so we would hang if we had multiple overlapping requests for data from more than one proc on the node.
Update PMIx to v1.1.2
This commit removes a check that causes mca_base_group_register to
improperly create a new group instead of using an existing group
when the project and framework names are the same. This check was
originally intended to prevent forming groups with names like
ompi_ompi, opal_opal, etc but there is no reason why we shouldn't
allow that.

Mofed 2.2 does not have the IBV_EXP_QP_INIT_ATTR_ATOMICS_ARG attribute
flag. Add a check to fix compilation for mofed 2.2. This commit only
fixes complilation with the older mofed. It will not allow an Open MPI
compiled with mofed 2.3 or newer to work on a machine with mofed 2.2.

If btl-portals4 is configured to use logical mapping of ranks to
physical nodes, then the endpoint must have the rank field set.
This commit fixes a bug that caused the endpoint to have the
nid/pid instead of the rank if the endpoint already exists.
some of the collective modules. Added a new function
opan_datatype_span, to compute the memory span of
count number of datatype, excluding the gaps in the
beginning and at the end. If a memory allocation is
made using the returned value, the gap (also returned)
should be removed from the allocated pointer.
This update adds an additional check (if supported) to see if 8-byte
atomics are supported by the hardware. If 8-byte atomics are not
supported the atomics support is disabled.
This commit also includes some cleanup.

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.
This commit adds support for fetch-and-add and compare-and-swap when
using the mlx5 driver. The support is only enabled if the expanded
verbs interface is detected. This is required because mlx5 HCAs return
the atomic result in network byte order. This support may need to be
tweaked if Mellanox commits their changes into upstream verbs.

OPAL free lists can be initialized with a fragment size that differs
from the size of objects from a class. This allows the free list code
to support OPAL objects that have flexible array members.
Unfortunately the free list code will throw out the desired length in
some cases. The code in question was committed in
open-mpi/ompi@90fb58de. The side effects of this are varied and can
cause segmentation faults, assert failures, hangs, etc. This commit
adds a check to ensure the requested size is at least as large as the
class size and makes opal_free_list allocations always honor the
requested fragment size (as long as it is larger than the class
size).

This commit revives the component retention functionality that was
removed as part of the component repository rewrite. The new

Also add an MCA param pmix_base_collect_data to direct that the blocking fence shall return all data to each process. Obviously, this param has no effect if async_

Move the fake usnic IBV provider out of common/verbs and into a new
common/verbs_usnic component that is always statically linked into
libopen-pal. The fake provider is registered with libibverbs at run
time, but there is no *un*register IBV API. Hence, we can't let the
code containing this provider be dlclosed -- which means it needs to
be statically linked into libopen-pal.

This commit fixes the following bugs:
- On send failure release newly allocated message.
- In the destructor for udcm_message_sent_t always remove the send
timeout event from the event base. Failure to do this can lead to
memory corruption since the destructor may be called from an event
callback.

This commit removes the service and async event threads from the
openib btl. Both threads are replaced by opal progress thread
support. The run_in_main function is now supported by allocating an
event and adding it to the sync event base. This ensures that the
requested function is called as part of opal_progress.

This commit adds a access_flags argument to the mpool registration
function. This flag indicates what kind of access is being requested:
local write, remote read, remote write, and remote atomic. The values
of the registration access flags in the btl are tied to the new flags
in the mpool. All mpools have been updated to include the new argument
but only the grdma and udreg mpools have been updated to make use of
the access flags. In both mpools existing registrations are checked
for sufficient access before being returned. If a registration does
not contain sufficient access it is marked as invalid and a new
registration is generated.
