ff669e7b15 code cleanup: clang is now a happier panda
Clang 5.1 on my mac was a sad panda compiling a couple
of files,  complaining about uninitialized stack variables.

This commit makes clang a happier panda (or at least not so sad).

60e91e890a coll/base: give a boost to ompi_coll_base_sendrecv_nonzero_actual()
Based on current implementation it is faster to use a blocking
send than the non-blocking version. Switch the exchange function
used in the barrier to use the blocking version combined with
the non-blocking version of the receive.

This is similar to open-mpi/ompi@223d75595d

0a09f8bc51 coll/hcoll: Protect module destruct when not fully initialized
* If hcoll is given a negative priority, but not enabled=0 then
   the module is constructed, but then destructed before calling
   it's query(). So the previous pointers are not initialized.
   If we try to OBJ_RELEASE them in a debug build an assert will fire.
   This commit adds some protection against that and initializes
   the _module pointers to NULL.

59f304b9e9 coll/base: neg. priority cleanup, verbose output improvements
* Print a verbose message if the component was disqualified because of
   a negative priority.
 * If a disqualified component provided a module, release it.
 * Display list of selected components in priority order
   - During the process of volunteering collective functions for a
     communicator, print the component name and priority. This will
     cause the verbose messages to be displayed in reverse priority
     order (lowest priority first, up to highest). This is helpful
     when determining which collective components are active in which
     order for a given communicator.
     To see the messages you need the following MCA parameter set to 9
     or higher: `-mca coll_base_verbose 9`
 * Adjust verbose for commonly needed verbose output from 10 to 9 to
   make it easier to access this information.

b90c83840f Refactor the request completion (#1422)
* Remodel the request.
Added the wait sync primitive and integrate it into the PML and MTL
infrastructure. The multi-threaded requests are now significantly
less heavy and less noisy (only the threads associated with completed
requests are signaled).

* Fix the condition to release the request.

57eadb0dd6 Fix for Coverity CID 1357152.
Or at least that was the origin of the issue. It turns out
we were freeing the wrong buffer (but as it only happen in the
case of an error we never noticed).

4b38b6bd0c Fix multiple issues with the collective requests.
This patch addresses most (if not all) @derbeyn concerns
expressed on #1015. I added checks for the requests allocation
in all functions, ompi_coll_base_free_reqs is called with the
right number of requests, I removed the unnecessary basic_module_comm_t
and use the base_module_comm_t instead, I remove all uses of the
COLL_BASE_BCAST_USE_BLOCKING define, and other minor fixes.

c8b077f232 coll/ml: fix coverity issues
Fix CID 715744 (#1 of 1): Logically dead code (DEADCODE):
Fix CID 715745 (#1 of 1): Logically dead code (DEADCODE):

The free of scratch_num in either place is defensive programming. Instead of removing the free the conditional around the free has been removed to quiet the warning.

Fix CID 715753 (#1 of 1): Dereference after null check (FORWARD_NULL):
Fix CID 715778 (#1 of 1): Dereference before null check (REVERSE_INULL):

Fixed the conditional to check for collective_alg != NULL instead of collective_alg->functions != NULL.

Fix CID 715749 (#1 of 4): Explicit null dereferenced (FORWARD_NULL):

Updated code to ensure that none of the parse functions are reached with a non-NULL value.

Fix CID 715746 (#1 of 1): Logically dead code (DEADCODE):

Removed dead code.

Fix CID 715768 (#1 of 1): Resource leak (RESOURCE_LEAK):
Fix CID 715769 (#2 of 2): Resource leak (RESOURCE_LEAK):
Fix CID 715772 (#1 of 1): Resource leak (RESOURCE_LEAK):

Move free calls to before error checks to cleanup leak in error paths.

Fix CID 741334 (#1 of 1): Explicit null dereferenced (FORWARD_NULL):

Added a check to ensure temp is not dereferenced if it is NULL.

Fix CID 1196605 (#1 of 1): Bad bit shift operation (BAD_SHIFT):

Fixed overflow in calculation by replacing int mask with 1ul.
