552216f9ba scripted symbol name change (ompi_ prefix)
Passed the below set of symbols into a script that added ompi_ to them all.

Note that if processing a symbol named "foo" the script turns
    foo  into  ompi_foo
but doesn't turn
    foobar  into  ompi_foobar

But beyond that the script is blind to C syntax, so it hits strings and
comments etc as well as vars/functions.

d55b666834 Topic/monitoring (#3109)
Add a monitoring PML, OSC and IO. They track all data exchanges between processes,
with capability to include or exclude collective traffic. The monitoring infrastructure is
driven using MPI_T, and can be tuned of and on any time o any communicators/files/windows.
Documentations and examples have been added, as well as a shared library that can be
used with LD_PRELOAD and that allows the monitoring of any application.

Add documentation for pml_monitoring_enable_output parameter. Remove useless parameter in example
Set filename only if using mpi tools
Adding missing parameters for fprintf in monitoring_flush (for output in std's cases)
Fix expected output/results for example header
Fix exemple when using MPI_Tools : a null-pointer can't be passed directly. It needs to be a pointer to a null-pointer
Base whether to output or not on message count, in order to print something if only empty messages are exchanged

366d64b7e5 Move the collective structure outside the communicator.
As we changed the ABI (forcing a major release), we can limit
the size of the predefined communicators by moving the collective
structure outside the communicator. This might have a minimal,
but unnoticeable, impact on performance. This approach has been
discussed during the January 2017 devel meeting.

MPI_Allgatherv with MPI_IN_PLACE reads data from wrong location.

They were locating the MPI_IN_PLACE send buffer as
```c

             send_buf += ((ptrdiff_t)rcounts[i] * extent);

when it should be
```c
         send_buf = (char*)rbuf;
         send_buf += ((ptrdiff_t)disps[rank] * extent);
```
because disps[] specifies where things are in the v-style buffers.

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

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.

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.

Fix CID 1325868 (#1 of 1): Dereference after null check (FORWARD_NULL):
Fix CID 1325869 (#1-2 of 2): Dereference after null check (FORWARD_NULL):

Here reqs can indeed be NULL. Added a check to
ompi_coll_base_free_reqs to prevent dereferencing NULL pointer.

4d00c59b2e Cleanup the memory handling for temporary buffers in
some of the collective modules. Added a new function
opan_datatype_span, to compute the memory span of
count number of datatype, excluding the gaps in the
beginning and at the end. If a memory allocation is
made using the returned value, the gap (also returned)
should be removed from the allocated pointer.
