This commit fixes a bug introduced in
f62d26ddbc8cda4d985cceee531a2ec32406d1f6. That commit changed how
vader allocates fragment memory from the shared memory
segment. Unfortunately, the values used for the fragment sizes did not
include space for the fragment header. This can cause an overrun of
data from one fragment to the header of the next fragment.

Example:
For the list of hosts `a01,b00,a00` a regex is generated:
`a[2:1.0],b[2:0]`, where `a`-hosts prefixes moved to the begining,
it breaks the hosts ordering.
This commit fixes regex for that case to `a[2:1],b[2:0],a[2:0]`

treematch/km_partitioning.c #include "config.h",
but there is no such file when the embedded treematch is used.
In order to prevent the embedded treematch from incorrectly using
the config.h from the embedded hwloc, generate a dummy config.h.

Example:
For the nodelist `jjss,jjss0000001,jjss0000003,jjss0000002` a regular
expression was `jjss[0:0],jjss[7:1,3,2]` that led to incorrect unpacking
the first host as `jjs0`. This commit fixes an adding empty range for
not numeric hostnames. Here is the fixed regex for this exapmle:
`jjss,jjss[7:1,3,2]`

We missed an assert to check if ALLOW_OVERTAKE is set or not before
validating the sequence number and this will cause deadlock.

opal_config_bottom.h can only be #include'd in opal_config.h,

Some macros defined by the embedded hwloc ends up in opal_config.h
because hwloc configury m4 files are slurped into Open MPI. These
macros are not required here, and they might conflict with an external
hwloc install, so simply #undef them in hwloc/external/external.h
after including <opal_config.h> but before including the external
<hwloc.h>.

ACCUMULATE, unlike REDUCE, can use with derived
datatypes with predefinied operations, with some
restrictions outlined in MPI-3:11.3.4. The derived
datatype must be composed entierly from one predefined
datatype (so you can do all the construction you want,
but at the bottom, you can only use one datatype, say,
MPI_INT).

Provide the av_attr.count hint (number of addresses that will be
inserted into the address vector through the life of the process)
at initialization of the address vector. It's ok to be a bit
wrong, but some endpoints (RxR) can benefit by not going through
the slow growth realloc churn.

This commit fixes a problem reported on the mailing list with
individual writes larger than 512 MB.
The culprit is a floating point division of two large, close values.
Changing the datatypes from float to double (which is what is being
used in the fcoll components) fixes the problem.

With MTLs, there's no "other transport" when the remote side
does not have an active NIC, so we should print a useful error
message when the modex failed (indicating lack of a NIC on
the remote side).

Similar to #6286 rounding number of bytes into a single precision floating point value to round up the result of a division is a potential risk due to rounding errors.
- remove floating point operations for `round up`
- removes floating point conversion for round down (native behavior of integer division)

If MPI extensions are enabled, all
`ompi/mpiext/pcollreq/use-mpi/mpiext_*_usempi.h` are included in
`ompi/mpi/fortran/mpiext-use-mpi/mpi-ext-module.F90` and all
`ompi/mpiext/pcollreq/use-mpi/mpiext_*_usempif08.h` are included in
`ompi/mpi/fortran/mpiext-use-mpi-f08/mpi-f08-ext-module.F90` using
`#include` directives.
In `mpiext_*_usempi.h` and `mpiext_*_usempif08.h`, some MPI extension
may want to use constants or handles defined in the `mpi` module and
the `mpi_f08` module. For example, if you want to define a new
datatype in `mpi_f08_ext`, you'll need the definition of
`type(mpi_datatype)`. However, putting `use mpi_f08` line in thier
`mpiext_*_usempif08.h` may cause a compilation error if more than
one MPI extensions are enabled because the `use` statement must be
put prior to any variable declarations.
To resolve this problem, this commit puts `use mpi` and `use mpi_f08`
as first lines of `mpi-ext-module.F90` and `mpi-f08-ext-module.F90`
respectively.

Including `mpiext_*_mpifh.h` in the source file of the `mpi_f08_ext`
module is not always appropriate. For example, if you want to define
a new datatype in an MPI extension, the `include 'mpif-ext.h'` binding
defines the datatype as `integer` but the `use mpi_f08_ext` binding
defines it as `type(mpi_datatype)`. They conflict.
This commit allows each MPI extension to declare whether it wants to
include its `mpiext_*_mpifh.h` in `mpi_f08` and `mpi_f08_ext`
respectively. The default (no declaration) is 'want'.
See `ompi/mpiext/example/configure.m4` for an example.

This commit updates btl/vader to use an mpool for handling all shared
memory allocations (frags, fboxes).
Signed-off-by: Nathan Hjelm <hjelmn@lanl.gov>
This commit adds a new mpool base module type: basic. This module can
be used with an opal_free_list_t to allocate space from a
pre-allocated block (such as a shared memory region). The new module
only supports allocation and is not meant for more dynamic use cases
at this time.

Moving to a model where we have users actively _enable_ SEP feature for use
rather than opening SEP by default if provider supports it. This allows us to
not regress (either functionally or for performance reasons) any apps that were
working correctly on regular endpoints.
Also, providing MCA to specify number of OFI contexts to create and default
this value to 1 (Given btl/ofi also creates one by default, this reduces the
incidence of a scenario where we allocate all available contexts by default and
if btl/ofi asks for one more, then provider breaks as it doesn't support it).
While at it, spruce up README on SEP content.
