Unlike "orterun", "prun" is a PMIx-only program that discovers the DVM connection instead of requiring that we explicitly provide it. Only build "prun" if PMIx v2.x is available.
This gets the DVM working again, but still is showing problems for multiple executions. I'll detail those in a separate issue. Thus, the DVM should still be considered "broken".

Some OSes have hardcoded limits to prevent overflowing over an int32_t.
We can either detect this at configure (which might be a nicer but
incomplete solution), or always force the pipelined protocol over TCP.
As it only covers data larger than 1GB, no performance penalty is to be
expected.

as the writev and readv support a sum larger than a uint32_t
this version will work. For the other OSes a different patch
is required. This patch is a slight modification of the one
proposed by @ggouaillardet.

* Resolves#3705
* Components should link against the project level library to better
support `dlopen` with `RTLD_LOCAL`.
* Extend the `mca_FRAMEWORK_COMPONENT_la_LIBADD` in the `Makefile.am`
with the appropriate project level library:
```
MCA components in ompi/
$(top_builddir)/ompi/lib@OMPI_LIBMPI_NAME@.la
MCA components in orte/
$(top_builddir)/orte/lib@ORTE_LIB_PREFIX@open-rte.la
MCA components in opal/
$(top_builddir)/opal/lib@OPAL_LIB_PREFIX@open-pal.la
MCA components in oshmem/
$(top_builddir)/oshmem/liboshmem.la"
```
Note: The changes in this commit were automated by the script in
the commit that proceeds it with the `libadd_mca_comp_update.py`
script. Some components were not included in this change because
they are statically built only.

Adopting can fail if the server-side hole isn't available on the client.
We can fallback to other ways to load the topology.

This commit has two changes
1. Adding magic string during handshake can cause
issue when used with older version of MPI. Hence set
RCVTIMEO paramter to 2 second
2. Using single call during handshake instead of
two calls

As part of improvement towards tcp debugging
we are moving few BTL_ERROR to show_help and also
update the function behaviour of
mca_btl_tcp_endpoint_complete_connect to return
SUCCESS and ERROR cases.

As part of improvement towards handling failure case
in btl tcp we are using magic string to verify mpi
connection. In case if there is mismatch or missing
magic string we can identify that we are trying to
connect with someother process.

Moving non-blocking send/receive function to btl_tcp
will help reusing these function where ever needed.
In this case we plan to reuse receive function to
retrive magic string to validate established connection
is from mpi process.

Not sure how/when this got deleted, but put back the "Cisco usNIC"

Turns out that supplying NULL to group_register in the
mca_base_var_group_component_register is not a good
idea if one wants for ompi_info to work as intended.
The ugni and vader btl's both call this before
registering component variables. This borks up
the ompi_info works since NULL is supplied as the project
name. So, now supply the project name rather than
just NULL to group register.
Fixes#4020.
