This eliminates the "quasi-functional" notify API altogether.
The aio framework will be coming soon to replace it.
As a bonus, apps (legacy apps) that use the notification FDs
will see improved performance, since we don't have to context
switch to give them a notification.

If the underlying platform fails (FreeBSD is the only one I'm aware
of that does this!), we use a global lock or condition variable instead.
This means that our lock initializers never ever fail.
Probably we could eliminate most of this for Linux and Darwin, since
on those platforms, mutex and condvar initialization reasonably never
fails. Initial benchmarks show little difference either way -- so we
can revisit (optimize) later.
This removes a lot of otherwise untested code in error cases and so forth,
improving coverage and resilience in the face of allocation failures.
Platforms other than POSIX should follow a similar pattern if they need
this. (VxWorks, I'm thinking of you.) Most sane platforms won't have
an issue here, since normally these initializations do not need to allocate
memory. (Reportedly, even FreeBSD has plans to "fix" this in libthr2.)
While here, some bugs were fixed in initialization & teardown.
The fallback code is properly tested with dedicated test cases.

Modern Windows (Vista and later) have light weight Slim Read/Write locks
which only occupy 64 bits, and don't require any memory allocation to
create.
While here clean up a few more unreferenced variables found with the
Microsoft compilers.

This was the main blocker, I think, for the nanomsg legacy compat
shim. Now that we have this, it should be relatively straight-forward
to implement the legacy nanomsg API, including the SENDFD, RECVFD thing.

This change provides for a private callback in the message queues,
which can be used to notify the socket, and which than arranges for
the appropriate event thread to run.
Upper layer hooks to access this still need to be written.

This compiles correctly, but doesn't actually deliver events yet.
As part of this, I've made most of the initializables in nng
safe to tear-down if uninitialized (or set to zero e.g. via calloc).
This makes it loads easier to write the teardown on error code, since
I can deinit everything, without worrying about which things have been
initialized and which have not.
