A mindless task for a lazy weekend: convert all the README and
README.txt files to Markdown. Paired with the slow conversion of all
of our man pages to Markdown, this gives a uniform language to the
Open MPI docs.
This commit moved a bunch of copyright headers out of the top-level
README.txt file, so I updated the relevant copyright header years in
the top-level LICENSE file to match what was removed from README.txt.
Additionally, this commit did (very) little to update the actual
content of the README files. A very small number of updates were made
for topics that I found blatently obvious while Markdown-izing the
content, but in general, I did not update content during this commit.
For example, there's still quite a bit of text about ORTE that was not
meaningfully updated.

This commit removes the unnecessary call to `fi_getinfo()` when
initializing the MTL. `cq_data_size` is a domain attribute that will be
available to the MTL from the initial query itself. FI_DIRECTED_RECV is
a primary capability that has to be requested for a provider to enable
it, so adding that to the initial requirement. The redundant query was
also overwriting the contents of the prov object, which already had the
include/exclude filtering and multi-NIC logic applied to it.

Bcast: scatter_allgather and scatter_allgather_ring expect N_elem >= N_procs
Allreduce: rabenseifner expects N_elem >= pow2 nearest to N_procs
In all cases, the implementations will fall back to a linear implementation,
which will most likely yield the worst performance (noted for 4B bcast on 128 ranks)

The mca parameters coll_tuned_*_algorithm are ignored unless coll_tuned_use_dynamic_rules is true so mention that in the description.

PGI (20.4) compiler do not define this intrinsic, so only build
AVX512 support if _mm512_mullo_epi64() intrisic is defined.

8017f12 introduced a new function to get the package rank of a process,
which had a pass-by-value signature (opal_process_info_t); and coverity
was not happy about it. This commit changes the signature to take a
reference to opal_process_info_t instead.

If PMIX_PACKAGE_RANK is available, uses this value to select between multiple
NIC of equal distance between the current process. If this value is not
available, try to calculate it by getting the locality string from each local
process and assign a package_rank. If everything fails, fall back to using
process_id.rank to select the NIC. This last case is not ideal, but has a small
chance of occuring, and causes an output to be displayed to notify that this is
occuring.

I ran into this exact case on MacOS (the C and Fortran compiler have
different default linker search paths). Technically, we've always had
this problem, but it has just become a bit more likely for real people
to run into because we're now preferring the system-installed
Libevent.

A recent commit made the use_mpi_f08 bindings sym link into their
profile directory (just like we do for C and other bindings) instead
of having standalone PMPI-ized copies of the bindings. Make sure to
.gitignore the sym linked files.

Coverity complained about uninitialized variables; ensure that they
are initialized to 0 in all cases.
