Assign values to remaining constants

[raffenet]

Finish assigning values to constants as defined in OpenPMIx. This is
basically a revert of
a256e08
and
296edb4
from #359.

Refs #358.

FYI: I rebased the branch now that PR #359 is merged. It should pass CI now.

• You do not need to vote on every proposal
• If you have no opinion, don't vote - that is also useful data
• If you've already commented on this issue, please still vote so
  we know your current thoughts
• Not all proposals solve exactly the same problem, so we may end
  up accepting proposals that appear to have some overlap
  This is not a binding majority-rule vote, but it will be a very
  significant input into the corresponding ASC decision.

Here are the meanings for the emojis:

• Hooray or Rocket: I support this so strongly that I
  want to be an advocate for it
• Heart: I think this is an ideal solution
• Thumbs up: I'd be happy with this solution
• Confused: I'd rather we not do this, but I can tolerate it
• Thumbs down: I'd be actively unhappy, and may even consider
  other technologies instead
