Valgrind warns that *newtype is uninitialized when calling from
Fortran as e.g.
use mpi
integer :: t, err
call MPI_Type_create_f90_integer(5, t, err)
Since newtype is intent(out), this should not happen. There is
no reason to convert the type using PMPI_Type_f2c, only to over-
write it immediately afterwards. The other type_create_* functions
did not convert newtype.

(cherry picked from commit 62321be186dd7d3efcedc2e801f226f6660ea0c4)
Adding the implementations of the functions that were removed
from the MPI standard to the build list, regardless of the
state of the OMPI_ENABLE_MPI1_COMPAT.
According to the README, we want the OMPI_ENABLE_MPI1_COMPAT
configure flag to control which MPI prototypes are exposed in
mpi.h, NOT, which are built into the mpi library. Those will
remain in the mpi library until a future major release (5.0?)
NOTE: for the Fortran implementations, we instead define
OMPI_OMIT_MPI1_COMPAT_DECLS to 0 instead of
OMPI_ENABLE_MPI1_COMPAT to 1. I'm not sure why, but
this seems to work correctly.
Also changing the removed MPI_Errhandler_create implementation
to use the non removed MPI_Comm_errhandler_function prototype
(prototype remains unchanged from MPI_Comm_errhandler_fn)
NOTE: This commit is *NOT* a cherry-pick from master, because
on master, we are no longer building those symbols by
default, but on v4.0.x we _ARE_ still building these
symbols by default. This is because the v4.0.x branch
is to remain backwards compatible with v3.0.x, while at
the same time removing the "removed" symbols from mpi.h
(unless the user configures with --enable-mpi1-compatibility)

This commit fixes edge cases of `r = 38` and `r = 308`.
As defined in the MPI standard, `TYPE_CREATE_F90_REAL` and
`TYPE_CREATE_F90_COMPLEX` must be consistent with the Fortran
`SELECTED_REAL_KIND` function. The `SELECTED_REAL_KIND` function is
defined based on the `RANGE` function. The `RANGE` function returns
`INT(MIN(LOG10(HUGE(X)), -LOG10(TINY(X))))` for a real value `X`.
The old code considers only `INT(LOG10(HUGE(X)))` using `*_MAX_10_EXP`.
This commit adds `INT(-LOG10(TINY(X)))` part using `*_MIN_10_EXP`.
This bug affected the following `p`-`r` combinations.
| p | r | expected | returned | expected | returned |
| :------------ | --: | :-------- | :-------- | :------- | :-------- |
| MPI_UNDEFINED | 38 | REAL8 | REAL4 | COMPLEX16 | COMPLEX8 |
| 0 <= p <= 6 | 38 | REAL8 | REAL4 | COMPLEX16 | COMPLEX8 |
| MPI_UNDEFINED | 308 | REAL16 | REAL8 | COMPLEX32 | COMPLEX16 |
| 0 <= p <= 15 | 308 | REAL16 | REAL8 | COMPLEX32 | COMPLEX16 |
MPICH returns the same result as Open MPI with this fix.

around where MPI extension header files are installed (specifically:
the installation tree path does not need to match the source tree
path).
For reference, header files were installed like this :

- <prefix>/include/openmpi/ompi/mpiext/pcollreq/c/mpiext_pcollreq_c.h
and they are now installed like this :
- <prefix>/include/openmpi/mpiext/mpiext_pcollreq_mpifh.h
- <prefix>/include/openmpi/mpiext/mpiext_pcollreq_c.h

Commit 89da9651b inadvertantly #if'ed out both deprecated *and*
removed items from mpi.h. The intent was only to #if out items that
have been *removed* from the MPI specification and leave all items
that are merely deprecated.
This commit also re-orders the deleted typedef+functions to be in the
same order as they are listed in MPI-3.1 chapter 17, just to make
verifying/checking the code easier.
Note that --enable-mpi1-compatibility can still be used to restore
prototypes for the items that have been removed from the MPI
specification (e.g., MPI_Address()).

PR #5450 addresses MPI_IN_PLACE processing for basic collective algorithms.
But in conjunction with that, we need to check for MPI_IN_PLACE in tuned paths
as well before calling ompi_datatype_type_size() as otherwise we segfault.
MPI spec also stipulates to ignore sendcount and sendtype for Alltoall and
Allgatherv operations. So, extending the check to these algorithms as well.
