fixes #449 Want more flexible pipe events

This changes the signature of nng_pipe_notify(), and the associated
events.  The documentation is updated to reflect this.

We have also broken the lock up so that we don't hold the master
socket lock for some of these things, which may have beneficial
impact on performance.
