- ignore sendcounts, sendispls and sendtypes arguments when MPI_IN_PLACE is used
- use the right size when an inter-communicator is used.

Commit d7053a3 broke things for the case when Open MPI 4.0.x is built
without UCX support. Problem was it was trying to partially initialize
the btl to try and delay printing of a help message till wireup. Well
this sort of doesn't work in all cases. Rather than keep piling on
changes to support a help message for a BTL that we are deprecating, take
a keep it simple stupid approach.
So, revert most of d7053a3 and instead put the help message back in the
original location, during scan of ports of the available HCAs to check
for whether or not link layer for that port is configured for ethernet or infiniband.
If Open MPI was built with UCX support, don't emit the help message, if
UCX was not linked in, emit the help message.
Verified on a system with connectX5 HCAs configured with two ports configured
for ethernet and two for infiniband.

MPI standard states a user MPI_Op and/or user MPI_Datatype can be free'd
after a call to a non blocking collective and before the non-blocking
collective completes.
Retain user (only) MPI_Op and MPI_Datatype when the non blocking call is
invoked, and set a request callback so they are free'd when the MPI_Request
completes.

In common_ompi_aggregators calc_cost routine:
do not cast the real division to an int intermediately.
This patch removes the obsolete int variable c and assigns
the result of the P_a/P_x division directly to n_as.
With the intermediate int c variable, n_as gets 0 if P_a < P_x,
resulting in a division by 0 when computing n_s.

The procedure names don't contain "_f08" of Fortran 2008 bindings of
Persistent Collective Operations(mpiext/pcollreq/use-mpi-f08).
This fix adds "_f08" to the procedure names of pcollreq/use-mpi-f08,
same as other Fortran 2008 routines in `ompi/mpi/fortran/use-mpi-f08/mod`.

use strtol() instead of atoi() in order to handle hostnames
containing a large number.
This is a one-off commit for the release branches since
the regx framework has already been removed from master.
