Noah Evans ee3517427e Add threads framework
Add a framework to support different types of threading models including
user space thread packages such as Qthreads and argobot:

https://github.com/pmodels/argobots

https://github.com/Qthreads/qthreads

The default threading model is pthreads.  Alternate thread models are
specificed at configure time using the --with-threads=X option.

The framework is static.  The theading model to use is selected at
Open MPI configure/build time.

mca/threads: implement Argobots threading layer

config: fix thread configury

- Add double quotations
- Change Argobot to Argobots
config: implement Argobots check

If the poll time is too long, MPI hangs.

This quick fix just sets it to 0, but it is not good for the
Pthreads version. Need to find a good way to abstract it.

Note that even 1 (= 1 millisecond) causes disastrous performance
degradation.

rework threads MCA framework configury

It now works more like the ompi/mca/rte configury,
modulo some edge items that are special for threading package
linking, etc.

qthreads module
some argobots cleanup
