Fix the --nolocal option by ensuring we always check/remove the HNP from the list of available nodes if the flag is set
Ensure that the HNP node is included as available when nothing else is given

On unmanaged allocations, we need to update the total_slots_allocated once the daemons have been launched and "discovered" their topology

OMPI send and receive mesages use size_t for the lenght while PSM and PSM2
psm(2)mq_send/receive use uint32_t. Type size_t is 64 bits in 64 bits arch.
Therefore, this patch adds a sanity check on the lenght of the message
and fails gracefully.

The library that is installed is specific to Open MPI, so put an
"ompi_" prefix on it.
Also do some minor line wrappings and cleanups of text.

This change has the side effect of improving the performance of all
atomic data structures (in addition to making the code crrect under a
certain interpretation of the volatile usage).
This commit fixes#3450.

* Don't overflow the internal datatype count.
Change the type of the count to be a size_t (it does not alter the total
size of the internal structures, so has no impact on the ABI).

* Optimize the datatype creation.
The internal array of counts of predefined types is now only created
when needed, which is either in a heterogeneous environment, or when
one call get_elements. It saves space and makes the convertor creation a
little faster in some cases.
Rearrange the fields in the datatype description structs.
The macro OPAL_DATATYPE_INIT_PTYPES_ARRAY had a bug, and the
static array was only partially created. All predefined types should
have the ptypes array created and initialized.

* Respect the unpack boundaries.
As Gilles suggested on #2535 the opal_unpack_general_function was
unpacking based on the requested count and not on the amount of packed
data provided.
Fixes#2535.

`ompi_group_t::grp_proc_pointers[i]` may have sentinel values even
for processes which reside in the local node because the array for
`MPI_COMM_WORLD` is set up before `ompi_proc_complete_init`, which
allocates `ompi_proc_t` objects for processes reside in the local
node, is called in `MPI_INIT`. So using `ompi_proc_is_sentinel`
against `ompi_group_t::grp_proc_pointers[i]` in order to determine
whether the process resides in a remote node is not appropriate.
This bug sometimes causes an `MPI_ERR_RMA_SHARED` error when
`MPI_WIN_ALLOCATE_SHARED` is called, where sm OSC uses
`ompi_group_have_remote_peers`.

Do not pass param file MCA params if the user has requested that no param files be read - required when trying to avoid launch time penalties from large numbers of processes reading default param files. The daemon picks them up and passes them along anyway, so it isn't clear what value we gain from having them all read the defaults
