*	Add surveyor protocol (no tests yet).	Garrett D'Amore	2017-01-08
\| \| \| \| \| \| \|	This adds the surveyor protocol, and updates the respondent somewhat. I've switched to using generic names for per-pipe and per-socket protocol data. Hopefully this will make 'cut-n-paste' from other protocol implementations easier.
*	Move to generic socket & pipe workers, and up to 4 each.	Garrett D'Amore	2017-01-08
\| \| \| \| \|	This should eliminate all need for protocols to do their own thread management tasks.
*	Add respondent protocol. (Half of survey pattern.)	Garrett D'Amore	2017-01-08
\|
*	More close race fixing.	Garrett D'Amore	2017-01-07
\| \| \| \| \|	Don't drop the lock in sock_close while holding the pipe reference. I'm pretty sure this is responsible for the use-after-free race.
*	Clean up sender/recver threads.	Garrett D'Amore	2017-01-07
\|
*	Pipe bail shouldn't mess with lists. Doh!	Garrett D'Amore	2017-01-07
\|
*	Uncrustify fix for last.	Garrett D'Amore	2017-01-07
\|
*	Race condition fix attempt.	Garrett D'Amore	2017-01-07
\|
*	Simplify locking for protocols.	Garrett D'Amore	2017-01-07
\| \| \| \| \| \| \| \| \|	In an attempt to simplify the protocol implementation, and hopefully track down a close related race, we've made it so that most protocols need not worry about locks, and can access the socket lock if they do need a lock. They also let the socket manage their workers, for the most part. (The req protocol is special, since it needs a top level work distributor, and a resender.)
*	Initial swag at pipeline (PUSH/PULL).	Garrett D'Amore	2017-01-06
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	PUSH attempts to do a round-robin based distribution. However, I noticed that there is a bug in REQ, because REQ sockets will continue to pull down work until the first one no longer has room. This can in theory lead to scheduliung imbalances when the load is very light. (Under heavy load, the backpressure dominates.) Also, I note that mangos suffers the same problem. It does not make any attempt to deliver work equally, basically each pipe winds up pulling messages until its own buffers are full. This is bad. We can borrow the logic here for both REQ and mangos. None of this is tested yet.
*	Bunch of copyright fixes.	Garrett D'Amore	2017-01-06
\|
*	Message API was awkward.	Garrett D'Amore	2017-01-06
\| \| \| \| \| \| \|	The use of a single function to get both size and length actually turned out to be awkward to use; better to have separate functions to get each. While here, disable some of the initialization/fork checks, because it turns out they aren't needed.
*	Change a bunch of copyrights to 2017 for work done since the 1st.	Garrett D'Amore	2017-01-05
\|
*	PUB protocol (untested).	Garrett D'Amore	2017-01-05
\|
*	Add nng_shutdown() for sockets to help avoid close race.	Garrett D'Amore	2017-01-05
\| \| \| \|	Also we added a two phase shutdown for threads.
*	SUB protocol implemented (uses sorted linked list for topics).	Garrett D'Amore	2017-01-05
\|
*	Fix close related races (POSIX close is a PITA).	Garrett D'Amore	2017-01-04
\|
*	Test for duplicate address listen, and fix in TCP for same.	Garrett D'Amore	2017-01-04
\|
*	Initial cut at TCP, totally untested beyond compilation.	Garrett D'Amore	2017-01-04
\| \| \| \| \|	This also adds checks in the protocols to verify that pipe peers are of the proper protocol.
*	Working towards TCP support.	Garrett D'Amore	2017-01-03
\|
*	Add NNI_PUT64 and NNI_GET64.	Garrett D'Amore	2017-01-02
\|
*	Add NNI_GET32, NNI_PUT32 macros.	Garrett D'Amore	2017-01-02
\|
*	Fixes to enable REQ/REP to operate.	Garrett D'Amore	2017-01-02
\| \| \| \| \| \| \|	This uncovered a few problems - inproc was not moving the headers to the body on transmit, and the message chunk allocator had a serious bug leading to memory corruption. I've also added a message dumper, which turns out to be incredibly useful during debugging.
*	Begin testing REQ/REP.	Garrett D'Amore	2017-01-02
\|
*	Protocol initialization restructuring.	Garrett D'Amore	2017-01-02
\|
*	Endpoint renaming.	Garrett D'Amore	2017-01-02

\|
*	More structure allocation macro conversion.	Garrett D'Amore	2017-01-02
\|
*	Use new NNI_ALLOC_STRUCT macro. nni_msg_dup copies options too.	Garrett D'Amore	2017-01-02
\|
*	Uncrustify.	Garrett D'Amore	2017-01-01
\|
*	Final purge of old threading & synch stuff.	Garrett D'Amore	2017-01-01
\|
*	Endpoint uses single thread.	Garrett D'Amore	2017-01-01
\|
*	Socket reaper uses new-thread.	Garrett D'Amore	2017-01-01
\|
*	Message queues use new locking primitives.	Garrett D'Amore	2017-01-01
\|
*	Pipe simplifications for thread management.	Garrett D'Amore	2017-01-01
\| \| \| \| \| \| \|	This may also address a race in closing down pipes. Now pipes are always registered with the socket. They also always have both a sender and receiver thread. If the protocol doesn't need one or the other, the stock thread just exits early.
*	Nuke legacy _t types.	Garrett D'Amore	2017-01-01
\|
*	New thread infrastructure -- not used anywhere yet, but tested.	Garrett D'Amore	2017-01-01

\|
*	Free our per socket message queues.	Garrett D'Amore	2016-12-31
