This error code results when an AIO is stopped permanently, as a result
of nni_aio_close or nni_aio_stop. The associated AIO object cannot be
used again. This discrimantes against a file being closed, or a temporary
cancellation which might allow the aio to be reused.
Consumers must check for this error status in their callbacks, and not
resubmit an operation that failed with this error. Doing so, will result
in an infinite loop of submit / errors.

These options are removed entirely, and their functionality is now
available via special functions, `nng_socket_get_send_poll_fd` and
`nng_socket_get_recv_poll_fd`, making these first class methods on
the socket.
This eliminates a bit of wasteful code, and provides type safety
for these methods.

This makes these functions entirely bullet proof, and eliminates
yet more error handling cases.

Nothing is using this, but it adds complexity and also requires
additional lock activity each time a socket is opened.

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.

fixes #538 setopt should have an explicit chkopt routine
fixes #537 Internal TCP API needs better name separation
fixes #524 Option types should be "typed"
This is a rework of the option management code, to make it both clearer
and to prepare for further work to break up endpoints. This reduces
a certain amount of dead or redundant code, and actually saves cycles
when setting options, as some loops were not terminated that should have
been.

* fixes #419 want to nni_aio_stop without blocking
This actually introduces an nni_aio_close() API that causes
nni_aio_begin to return NNG_ECLOSED, while scheduling a callback
on the AIO to do an NNG_ECLOSED as well. This should be called
in non-blocking close() contexts instead of nni_aio_stop(), and
the cases where we call nni_aio_fini() multiple times are updated
updated to add nni_aio_stop() calls on all "interlinked" aios before
finalizing them.
Furthermore, we call nni_aio_close() as soon as practical in the
close path. This closes an annoying race condition where the
callback from a lower subsystem could wind up rescheduling an
operation that we wanted to abort.

This provides context support for REQ and REP sockets.
More discussion around this is in the issue itself.
Optionally we would like to extend this to the surveyor pattern.
Note that we specifically do not support pollable descriptors
for non-default contexts, and the results of using file descriptors
for polling (NNG_OPT_SENDFD and NNG_OPT_RECVFD) is undefined.
In the future, it might be nice to figure out how to factor in
optional use of a message queue for users who want more buffering,
but we think there is little need for this with cooked mode.

This makes the raw mode something that is immutable, determined
at socket construction. This is an enabling change for the
separate context support coming soon.
As a result, this is an API breaking change for users of the raw
mode option (NNG_OPT_RAW). There aren't many of them out there.
Cooked mode is entirely unaffected.
There are changes to tests and documentation included.

fixes #302 nng_dialer/listener/pipe_getopt_sockaddr desired
This adds plumbing to pass and check the type of options
all the way through.
NNG_ZT_OPT_ORBIT is type UINT64, but you can use the untyped form to
pass two of them if needed.
No typed access for retrieving strings yet. I think this should allocate
a pointer and copy that out, but that's for later.

This introduces enough of the HTTP API to support fully server
applications, including creation of websocket style protocols,
pluggable handlers, and so forth.
We have also introduced scatter/gather I/O (rudimentary) for
aios, and made other enhancements to the AIO framework. The
internals of the AIOs themselves are now fully private, and we
have eliminated the aio->a_addr member, with plans to remove the
pipe and possibly message members as well.
A few other minor issues were found and fixed as well.
The HTTP API includes request, response, and connection objects,
which can be used with both servers and clients. It also defines
the HTTP server and handler objects, which support server applications.
Support for client applications will require a client object to be
exposed, and that should be happening shortly.
None of this is "documented" yet, bug again, we will follow up shortly.

This makes all the protocols and transports optional. All
of them except ZeroTier are enabled by default, but you can
now disable them (remove from the build) with cmake options.
The test suite is modified so that tests still run as much
as they can, but skip over things caused by missing functionality
from the library (due to configuration).
Further, the constant definitions and prototypes for functions
that are specific to transports or protocols are moved into
appropriate headers, which should be included directly by
applications wishing to use these.
We have also added and improved documentation -- all of the
transports are documented, and several more man pages for
protocols have been added. (Req/Rep and Surveyor are still
missing.)

This makes the APIs use string keys, and largely eliminates the use of
integer option IDs altogether. The underlying registration for options
is also now a bit richer, letting protcols and transports declare the
actual options they use, rather than calling down into each entry point
carte blanche and relying on ENOTSUP.
This code may not be as fast as the integers was, but it is more intuitive,
easier to extend, and is not on any hot code paths. (If you're diddling
options on a hot code path you're doing something wrong.)

fixes #38 Make protocols "pluggable", or at least optional
This is a breaking change, as we've done away with the central
registered list of protocols, and instead demand the user call
nng_xxx_open() where xxx is a protocol name. (We did keep a
table around in the compat framework though.)
There is a nice way for protocols to plug in via
an nni_proto_open(), where they can use a generic constructor
that they use to build a protocol specific constructor (passing
their ops vector in.)

This should eliminate all need for protocols to do their own
thread management tasks.

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.)

At this point listening and dialing operations appear to function properly.
As part of this I had to break the close logic up since otherwise we had a
loop trying to reap a thread from itself. So there is now a separate reaper
thread for pipes per-socket. I also changed lists to be a bit more rigid,
and allocations now zero memory initially. (We had bugs due to uninitialized
memory, and rather than hunt them all down, lets just init them to sane zero
values.)

There's work to do still, but I've left clear indications of the
design in comments. Some ugly mysteries are now solved.
