Revamp the query implementation

Resolve the hang in the blocking query API. Strip out the
unnecessary code. Cache results as we go so we don't lose
initial results when we go to the server and/or the host.

Fix format of fetch response for peer's version

When a client asks the server for information, the server
must format the response to match the PMIx version employed
by the client. We were incorrectly formatting the response
on the basis of the version declared by the process whose
data was being requested - as opposed to the version of
the requestor.

In the case of tools, this led to an incorrectly formatted
response, particularly for node-level data where earlier
PMIx versions didn't support the node-info array.

Looking at this also exposed that the client's version
was defaulting to 0.0.0, and would remain that way if
the client application did not call PMIx_Init. Needed
to adjust the macro that checks for PMIx version level
to deal with non-PMIx clients.
