This uses numeric identifiers and an idhash table to make sure that
the values we get back are still use.

This also gives a performance benefit to WebSocket, by making
the completion logic run synchronously.

fixes #22 Consider using synchronous completions sometimes
Transport improvements for IPC, TCP, and TLS.
This change does three things.
First it permits multiple outstanding receives or sends on the transport.
This change is being made to accomodate some other changes in the protocols
where it might be advantageous to post send or receives directly against
the transport pipe without going through another level of indirection.
Second, it changes the normal completions to be performed synchronously.
This translates into a rather major performance improvement, reducing
latency by some 27%, and thereby improving performance altogether. (This
elminates two extra context switches per transaction!)
FInally, we can save some extra checks and conditions because we know
that completions cannot happen if we don't have a pending operation
(we no longer complete out of sequence), and we only call the dosend
operation when we have something to send. This can eliminate some
pipeline stalls.

This includes platform portability stuff like mutexes and threads,
etc. While here we fixed a problem with nng_opts_parse and we
addressed the type of the platform API.

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.

on a python wrapper (cffi).
Mostly this is fixing inconsistencies in our public API and the actual
implementation.

Actually I updated all the option related documents, and fixed minor
markup issues on several others.

fixes #275 nng_pipe_getopt_ptr() missing?
fixes #285 nng_setopt_ptr MIS
fixes #297 nng_listener/dialer_close does not validate mode
This change adds some missing APIs, and changes others.
In particular, certain options are now of type bool, with size
of just one. This is a *breaking* change for code that uses those
options -- NNG_OPT_RAW, NNG_OPT_PAIR1_POLY, NNG_OPT_TLS_VERIFIED.

Mostly this eliminates some cases of extra backticks.

While here we documented that certain options are not supported in the
compatibility layer.

fixes #279 consider restructuring man sections
This represents a rather significant rework, and major editing
effort, for the entire set of manual pages.
All of the pages now have a section number in their filename;
this assists in some other tooling, particularly ebook generation
as every link needs to be programmatically modified when combined
into an ebook.
Section 5 is introduced, and populated with pages for the main
types, and all options are now documented.
Numerous errors have been corrected, including rewriting certain
portions such as the header section of the surveyor protocol.
Much work has been done to facilitate index generation, although
certainly more work remains here.
Every internal link within these pages now resolves; there are no
more dead links. (This is required to generate Kindle format books.)

This starts a new section 5 for generic topics, and sets up some links
for things like nng_duration and nng_socket types. There will some day
be an nng_errors(5) page as well.
Some initial work towards indexing terms for these pages is done now too.
(Indexing will mostly be useful when generating book forms of this
documentation.)

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.

The comments had way too much leading whitespace. While this looks fine
in PDF and HTML, it's pretty ugly on most ereaders.

There are still some busted links that have to be fixed,
but these are the ones that are just typos or trivially
fixed. There is of course some content still missing.

This does a few things. First it closes a case where a dropped
message could prevent subsequent connection attempts from getting through.
Second, it changes the rate at which we retry, and the timeout, to be
a lot more aggressive when attempting to establish a connection. We
retry every 500 ms, for up to 2 minutes, before giving up. This gives
a lot more resilience in the face of message loss that is typical of
ZeroTier in some environments when first establishing communication.
Third, makes the values for the connection attempts *tunable*, so
that applications can adjust for different deployment scenarios.
Fourth, it includes the ability to get the UDP socket name. This was
needed during some debug, and may be useful for a real UDP transport
later, so we're keeping it.
Finally, we added documentation for the above items.
