fixes #815 Eliminate socket filters on message queues

This also eliminates the enforcement of NNG_OPT_RECVMAXSZ for inproc,
which never really made much sense.  This helps inproc go faster.
While here, also clean up the entry point for protocols to support
a drain option, since we don't use that anywhere.
