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.

FCA barrier may not complete if FCA progress is not called periodically.
PMI/PMI2 API that can be used in rte barrier has no provision for calling
external progress function.
So it is possible that during finalize some ranks will be stuck
in fca barrier while others are in PMI barrier.
Fixes CID 72320: Explicit NULL dereferenced
On error it is possible that the blocklen_per_process array is
NULL. Change the NULL check before the free to check for non-NULL on
the array not the array element. Also clean up allocation of this
array to use calloc instead of malloc + setting each element to NULL.

Fixes CIDs 72300, 72344, 1196764-1196768, 72300: Resource leaks
Mulitple allocated arrays are going out of scope at the end of
mca_fcoll_two_phase_file_write_all. Free these arrays. Also removed
the extraneous NULL checks since free (NULL) is safe in C.
Change returns to goto exit where the allocated resources are freed.
Fixes CIDs 72285-72292, 72297, 72298: Resource leaks
Change all appropriate return statements to goto exit to ensure that
all resources are freed. Also removed the NULL checks since free
(NULL) is safe in C.
Fixes CIDs 72295, 72296: Resource leaks
Moved free of requests and recv_types to after exit label. This will
ensure these are freed on error.
Also added a loop and statement to free send_buf which is going out of
scope at the end of the function.
Fixes CIDs 72336-72240, 735197, 735198: Resource leaks
Moved the exit label before to before the resources are released and
changed all appropriate return statements to goto exit. Also removed
extraneous NULL checks because free (NULL) is safe in C.
Fixes CIDs 72341, 72343, 1196805-1196809: Resource leaks
Free all resources after exit label and change return statements to
goto exit to ensure all resources are freed on error.
Fixes CID 1269973: Unused value
Check return code of ompi_request_wait_all. If it fails jump to the
exit.
Fixes CID 714119: Dereference before NULL check
Wrong value checked in conditional.

./configure --with-platform=contrib/platform/$name will apply all patches
found in contrib/platform/$name.patches/ directory during "configure" phase.
It allows vendors to distribute not-accepted or vendor-specific patches as
part of standard ompi tarball and reduce burden of keeping private repos.
Added:
* VPATH support
* $srcdir/.platform_patches file created if patches already applied
* configure will fail with error if patch cannot be applied (using dry-run)
* configure will fail if patches modifying *.[am,m4] files (unsupported)
* remove unused patch_errors var
* set with_ident_string if platform file applied patches
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)
Fixes CID 1323841: Logically dead code
Wrong value in conditional. Should be newcomp not newcomm.
Fixes CID 1269762: Explicit null dereference
ompi_group_incl could return an error and not set local_group. Add a
check to ensure ompi_group_incl succeeded before incrementing the proc
count.

Fix CID 1315271: Constant expression result
The intent of this conditional is to not produce a peruse event for
probe or mprobe requests. Coverity is correct that the expression is
always true. Changed the || to && to fix. Also moved the conditional
within an OMPI_WANT_PERUSE to ensure the conditional is not evaluated
if peruse is disabled.
