These macros should really be named OPAL_SUMMARY_*; they're used in
all projects, and therefore should be in the lowest later project (OPAL).

MPI_LONG_LONG_INT is a named predefined datatype, so its name is now MPI_LONG_LONG_INT
MPI_LONG_LONG is a synonym of MPI_LONG_LONG_INT, and its name is also MPI_LONG_LONG_INT
Fix CID 72362: Explicit null dereferenced (FORWARD_NULL)
From what I can tell the code @ fcoll_static_file_read_all.c:649
should be setting bytes_per_process[i] to 0 not bytes_per_process.
Fix CID 72361: Explicit null dereferenced (FORWARD_NULL)
Modified check to check for blocklen_per_process non-NULL before
trying to free blocklen_per_process[l]. This is sufficient because
free (NULL) is safe. Also cleaned up the initialization of this an a
couple other arrays. They were allocated with malloc() then
initialized to 0. Changed to used calloc().

Fix CID 72296: Resource leak (RESOURCE_LEAK):
Changed code to goto exit instead of returning to ensure memory is
freed.
Fix CID 712589: Out-of-bounds read (OVERRUN):
In this loop i and j are identical and always less than
iov_count. The CID was triggered because i was incremented if i was <
iov_count. This meant that if the loop did go on the next iteration
would access an invalid index.
Fix CID 741363: Uninitialized scalar variable (UNINIT):
Allocate tmp_len with calloc to insure every index is initialized.
Fix CID 741364: Uninitialized pointer read (UNINIT):
Allocate recv_types with calloc to ensure all indices are always
initialized. Also added a check to not loop and destroy if recv_types
is NULL.
Also added a NULL check on the allocation of decoded iov. This is not
the cause of CID 126784 but should be fixed.
Fix CID 712588: Out-of-bounds read (OVERRUN):
Similar to CID 712589. Should silence the issue.

Fix CID 1358512: Error handling issues (NEGATIVE_RETURNS):
C libraries usually handle read (-1, ...) fine but it is safer to
avoid calling read with a negative handle. Added negative file
descriptor check.

openshmem.org specification does not mention about extension api
but there is an agreemnet to do these changes for related ex api too.

Annex G:
Version 1.3
Added const to every read-only pointer argument
Because of the removal of the linux memory component it is no longer
necessary to initialize the memory component in opal_init(). This
commit moves the initialization to the creation of the first rcache
component.

This commit fixes bugs that can cause crashes and memory corruption
when the mremap hook is called. The problem occurs because of the
ellipses (...) in the mremap intercept function. The ellipses cover
the optional new_addr argument on Linux. This commit removes the
ellipses and adds an explicit 5th argument.
This commit also adds a hook for shmdt. The code only works on Linux
at the moment as it needs to read /proc/self/maps to determine the
size of the shared memory segment.
Additionally, this commit removes the mmap hook. There is no
apparent benefit for detecting mmap(..., PROT_NONE, ...) and it
seems to cause problems when threads are in use.

This commit removes the ptmalloc2 memory hooks. This is necessary in
order to support lazy registration of memory hooks. A feature that is
not supported by the ptmalloc hooks but is supported by the new
patcher hooks.
