KAWASHIMA Takahiro b9316d3136 fortran/use-mpi-f08: Correct f08 routine signatures
Following the commit f750c6932c, I compared
`ompi/mpi/fortran/use-mpi-f08/*.F90` and
`ompi/mpi/fortran/use-mpi-f08/profile/p*.F90`, and
`ompi/mpi/fortran/use-mpi-f08/mod/mpi-f08-interfaces.F90` and
`ompi/mpi/fortran/use-mpi-f08/mod/pmpi-f08-interfaces.F90`.

There are many differences. Some are bugs of `MPI_*`, some are
bugs of `PMPI_*`. I'm not sure how these bugs affect applications.

To make it easy to compare these files future, I also removed
editorial differences.

! Note that we pass a scalar here for both the sendtypes and
! recvtypes arguments, even though the real Alltoallw function
! expects an array of integers. This is a hack: we know that
! [send|recv]types(1)%MPI_VAL will pass the address of the first
! integer in the array of Type(MPI_Datatype) derived types. And
! since Type(MPI_Datatype) are exactly memory-equivalent to a
! single INTEGER, passing the address of the first one is the same
! as passing the address to an array of integers. To be clear: the
! back-end ompi_alltoallw_f is expecting a pointer to an array of
! integers. So it all works out (but is a hack :-\ ).
