There is no valid use for this, once we added the ability to
query the bound port.

More direct access methods are provided instead.
This results in much lower friction when using, and is a step on the path
to removing NNG_OPT_LOCADDR as well.
We need to figure a solution for NNG_OPT_LOCADDR for dialers; for
listeners there is little use in it either, and it will be removed.
(Dialers will probably get a new NNG_OPT_BIND_IP option.)

This is easier and agnostic about the underlying L3 protocol.
We plan to remove direct NNG_OPT_LOCADDR support from listeners
(and probably both NNG_OPT_LOCADDR and NNG_OPT_REMADDR have numbered
days left in their lifetime. They will be replaced with more direct
typed access functions as has been done for pipes already.)
While here fixed some include for IWYU in the POSIX platform.

This is going to be used to facilitate debugging, and eliminate some
inconveniences around these things. We plan to move the pipe functions
to use these directly, hopefully moving away from the pipe_getopt hack.
(The transport API will need to grow these. For now this is just the
streams.)

We are *only* supporting 3.5 (or newer 3.x releases) as its the newest LTS version of OpenSSL.
This supports the full set of TLS features with NNG, including DTLS, PSK, TLS 1.3, etc.
Future work will explore making using of the QUIC support in OpenSSL.
Note that this OpenSSL work sits on top of NNG's TCP streams, so it cannot benefit from
Linux in-kernel TLS or other features such as TCP fast open at this time.

This avoids needless allocations, and we offer for pipes (which need
this because they might be ephemeral) the get_strdup, get_strcpy,
and get_strlen forms. (Those do the copying or allocations while holding
the pipe reference.)

This will replace the NNG_OPT_TLS_PEER_ALTNAMES and NNG_OPT_TLS_PEER_CN
properties, and gives a bit more access to the certificate, as well as
direct access to the raw DER form, which should allow use in other APIs.

* adds nng_dialer_start_aio
This change adds `nng_dialer_start_aio` (if you have a better name, I'm
happy to change it), whose docs read:
> `nng_dialer_start_aio` starts the endpoint dialing asynchronously.
> This is only possible if the dialer is not already dialing. Unlike
> `nng_dialer_start`, this accepts an AIO such that the caller can learn
> when the dialing eventually succeeds or fails. The supplied AIO must
> have been initialized, and is only triggered with the result of the
> first dial attempt.
This new function makes it possible for applications to perform a
non-blocking dial, but still later be notified of the result of that
dial. Arguably, this obviates the need for `NNG_FLAG_NONBLOCK` in
`dialer_start` altogether, but no need to break backwards compatibility.
There is technically a functional change here, which is that the
"Starting dialer for socket" message now gets printed _before_ the dial
is complete in the blocking case, rather than after. It's possible to
change this if we're willing to make the code slightly more complicated,
but given it says "Starting", not "Started", this change felt fine.

This replaces the int, and we will expand this further, as this
makes it clear that the int is actually an error code and helps in
debuggers that can provide symbolic values.

The data is now passed directly to the handler function.

Nothing really needs it -- we kept it in 1.0 to preserve semantics,
but there is no requirement for semantic preservation in 2.0.

This represents a major change in the HTTP code base, consisting
of a complete revamp of the HTTP API. The changes here are too
numerous to mention, but the end result should be a vastly
simpler API for both server and client applications.
Many needless allocations were removed by providing fixed buffers
for various parameters and headers when possible.
A few bugs were fixed. Most especially we have fixed some bugs
around very large URIs and headers, and we have also addressed
conformance bugs to more closely conform to RFCs 9110 and 9112.
As part of this work, the APIs for WebSockets changed slightly
as well. In particular the properties available for accessing
headers have changed.
There is still documentation conversion work to do, and additional
functionality (such as proper support for chunked transfers), but
this is a big step in the right direction.

This simplified API lets callbacks obtain the response from the
connection objection directly, and does not require the aio to carry
it as a parameter. Further, the request and response are both
stored inline in the connection, reducing allocations.
This is at present only for the server; the client will get a similar
set of changes.

The API is identical, except that some names have changed, and this is now a
header library in `nng/args.h` - so the core library does not need to carry this
code in binaries. Being a header library also means it is not necessary to
link against NNG, and it does not include any parts of NNG; it only depends on
a standard C99 or C11 environment.
