Now Open MPI requires a C99 compiler. Checking availability of
the following types is no more needed.
- `long long` (`signed` and `unsigned`)
- `long double`
- `float _Complex`
- `double _Complex`
- `long double _Complex`
Furthermore, the `#if HAVE_[TYPE]` style checking is not correct.
Availability of C types is checked by `AC_CHECK_TYPES` in `configure.ac`.
`AC_CHECK_TYPES` defines macro `HAVE_[TYPE]` as `1` in `opal_config.h`
if the `[TYPE]` is available. But it does not define `HAVE_[TYPE]`
(instead of defining as `0`) if it is not available. So even if we
need `HAVE_[TYPE]` checking, it should be `#if defined(HAVE_[TYPE])`.
I didn't remove `AC_CHECK_TYPES` for these types in `configure.ac`
since someone may use `HAVE_[TYPE]` macros somewhere.

When the provider does not support FI_REMOTE_CQ_DATA, the OFI tag does not have
sizeof(int) bits for the rank. Therefore, unexpected behavior will occur when
this limit is crossed.
Check the max allowed number of ranks during add_procs() and return if there is
danger of exceeding this threshold.

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.

Some compilers complain when comparing signed and unsigned. romio321
was doing just this. The check is meant to check whether a size (which
is an ADIO_Offset-- a signed number) will work with memcpy which takes
a size_t. To silence the warning I added a new type (ADIO_Size) which
is an unsigned type and cast the ADIO_Offset to this new type.
Fixes#5951

The monitoring PML hides it's existence from the OMPI infrastructure by
removing itself from the list of PML loaded components, remaining hidden
until MPI_Finalize.

With this patch the best PML is selected earlier, before finalizing

Several fixes to string handling:
1. strncpy() -> opal_string_copy() (because opal_string_copy()
guarantees to NULL-terminate, and strncpy() does not)
2. Simplify a few places, such as:
* Since opal_string_copy() guarantees to NULL terminate, eliminate
some memsets(), etc.
* Use opal_asprintf() to eliminate multi-step string creation
There's more work that could be done; e.g., this commit doesn't
attempt to clean up any strcpy() usage.

While we require C99 to build Open MPI, we do not require C99 to build
user MPI applications. As such, we shouldn't have C99-style comments
(i.e., "//"-style) in mpi.h.in.
Thanks to @AdamSimpson for reporting the issue.
This commit simply converts a //-style comment to a /**/-style
comment. No code or logic changes.
