if CFLAGS and/or CPPFLAGS are passed to the ompi configure command line, pmix1xx
configure will not use the correct ones previously passed in the environment

Thanks Siegmar Gross for bringing this to our attention
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 was fixed on my btl 3.0 branch but the changeset got lost in a
rebase. Fixes issues with lock ups when using osc/rdma.

The mca_base_select function uses returned priorities to select the
best component/module. This priority may be of use to the caller so
pass that information back in an optional argument. If the priority is
not needed pass NULL.

The handling of RDMA get alignment in ugni BTL for Aries
(cray xc) was wrong, resulting in very poor bandwidth
for ugni BTL on aries.
Verified using osu_bw now gives sensible bandwidth on
Aries.

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.

Otherwise libpciaccess sends a big error message to stderr:
Error opening /devices/pci@0,0:reg: Permission denied
(cherry picked from commit open-mpi/hwloc@d93c7c0960)
In the default mode of operation, the Portals4 components support
dynamic add_procs().
The Portals4 components have two alternate modes (flow control and
logical-to-physical) that require knowledge of all procs at startup.
In these modes, mtl-portals4 sets the MCA_MTL_BASE_FLAG_REQUIRE_WORLD
flag and btl-portals4 sets the MCA_BTL_FLAGS_SINGLE_ADD_PROCS flag
to tell the PML that we need all the procs in one add_procs() call.
After PMIx integration, the thrid parameter to OPAL_MODEX_RECV() is
opal_process_name_t instead of opal_proc_t. This commit replaces
proc with &proc->proc_name.
This required modifying the mca_component_select function to actually check the return code on a component query - it was blissfully ignoring it.
Also do a little cleanup to avoid bombarding the user with multiple error messages.
Thanks to Patrick Begou for reporting the problem
