The first problem was that using nng_sleep_aio
was found to reset the timeout, and this caused subsequent
operations to start failing with timeouts when reusing
the AIO for other operations.
The second thing is that we think it would be nicer if the
presence of real aio timeouts were still honored, so that
if the timeout is shorter than the sleep time, then we get
back an NNG_ETIMEDOUT like every other operation, and we
get back a 0 if the logical sleep operation completes
normally.

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.)

While here we added a test for the aio stuff, and cleaned up some dead
code for the old fd notifications. There were a few improvements to
shorten & clean code elsewhere, such as short-circuiting task wait
when the task has no callback.
The legacy sendmsg() and recvmsg() APIs are still in the socket core
until we convert the device code to use the aios.
