This comit adds code that sets the fragment reg_cnt to 1 when sending
the completion message for an eager get. Without this the btl will
either hang or abort.

Added mca parameter to turn progress thread on/off
Add a flag to check if we have btl progress thread.
Added macro for ob1 matching lock.
Update the AUTHORS file.
All BTL-only operations (basically all data movements
with the exception of the matching operation) can now
be handled for the TCP BTL by a progress thread.
The reference counting was broken which led PMIx_Finalize
to release resources early. This fixes the "use after free" scenarios
that I encountered.
(based on commit pmix/master@abfaa4c)
This reverts commit open-mpi/ompi@f7257a8310.
Ensure that we properly cleanup the session directory tree. Prior code had issues with symlinks, especially if the file that the link points to was already removed as we traverse the tree. Also found that the dirent checks for directory type weren't fully portable, and so fall back to the stat-based approach which is known to be portable.
Fix singularity singletons by detecting we are in a container and properly setting the pmix selection to pick the isolated component. Remove a stale restriction blocking use of the sm btl
This commit brings the scif btl up to date with changes made on master
to rework the mpool and rcache frameworks.

This commit uses the new flag "enumerator" to support comma-delimited
lists of flags for both the btl and btl atomic flags. After this
commit is is valid to specify something like -mca btl_foo_flags
self,put,get,in-place. All non-deprecated flags are supported by the
enumerator.

This commit adds a new type of enumerator meant to support flag
values. The enumerator parses comma-delimited strings and matches
each string or value to a list of valid flags. Additionally, the
enumerator does some basic checks to see if 1) a flag is valid in the
enumerator, and 2) if any conflicting flags are specified.

This commit adds the data necessesary for supporting dynamic add_procs
to the rdma message (opal_process_name_t). The endpoint lookup
function has been updated to match the code in udcm.

Fix CID 1345825 (1 of 1): Dereference before null check (REVERSE_INULL):
ib_proc should not be NULL in this case. Removed the check and added a
check for NULL after OBJ_NEW.
CID 1269821 (1 of 1): Dereference null return value (NULL_RETURNS):
I labeled this one as a false positive (which it is) but the code in
question could stand be be cleaned up.
Fix CID 1356424 (1 of 1): Argument cannot be negative (NEGATIVE_RETURNS):
While trying to silence another Coverity issue another was
flagged. Protect the close of fd with if (fd >= 0).
CID 70772 (1 of 1): Dereference null return value (NULL_RETURNS):
CID 70773 (1 of 1): Dereference null return value (NULL_RETURNS):
CID 70774 (1 of 1): Dereference null return value (NULL_RETURNS):
None of these are errors and are intentional but now that we have a
list release function use that to make these go away. The cleanup is
similar to CID 1269821.

Fix CID 1356358: Null pointer dereferences (REVERSE_INULL):
flist->fl_mpool can no longer be NULL. Removed the conditional.
Fix CID 1356357: Resource leaks (RESOURCE_LEAK):
Added the call to free the hints array.
Fix CID 1356356: Resource leaks (RESOURCE_LEAK):
This is a false error but it is safe to call close (-1) so just always
call close.
Fix CID 1356354: Control flow issues (MISSING_BREAK):
Fix CID 1356353: Control flow issues (MISSING_BREAK):
Add comments that indicate the fall-through is intentional.
Fix CID 1356351: Null pointer dereferences (FORWARD_NULL):
Fix potential SEGV if the page_size key is malformed.
Fix CID 1356350: Error handling issues (CHECKED_RETURN):
Add (void) to indicate that we do not care about the return code of
sscanf in this case.

+ Added an mca parameter to allow connecting processes from different
subnets. Its current default value is 'false' - don't allow, to keep the
current flow the way it is now.
+ rmdacm: when calling ibv_query_gid, use the gid index from
btl_openib_gid_index.
