prov/psm: document the assumption on the "event_in" parameter.

This parameter was added to the event creation routine to allow
the event being written to the user buffer directly, bypassing
the steps of allocating/enqueuing/dequeuing a new event. The user
buffer only has space for the CQ entry of the current CQ format.
Any provider provate information should not be written to it.

Makefile.am: clean out EXTRA_DIST

Several header files were listed in EXTRA_DIST.  Moved them all to
their corresponding _SOURCES macros.  This keeps core/provider header
files in their own distinct sections (vs. glumping .h files from
different providers in EXTRA_DIST).  The sockets .h file was already
listed in its _SOURCES macro.

dist: substitute ```@VERSION@``` and ```@DATE@``` tokens

During "make dist", iterate through README and all the man pages
substituting ```@VERSION@``` with the current version number and
```@DATE@``` with today's date (in the form YYYY-MM-DD).

man: fi_cntr_wait, fi_cq_sread clarify timeout

When these calls return due to timeout, they should return a
specific value, vs. a generic error. This indicates to the app
that it doesn't have to read the error queue.

man: mention CQs in fi_endpoint(3)

The fi_endpoint man page wasn't distinguishing between CQs and EQs
per our recent change. The data transfer completions now appear in
CQs not EQs. Passive endpoints need EQs, but not active endpoints.
