http: The big HTTP API refactoring of January 2025.v2.0.0-alpha.3http-client-trans

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.

-== NAME
-
-nng_http_client_connect - establish HTTP client connection
-
-== SYNOPSIS
-
-[source, c]
-----
-#include <nng/nng.h>
-#include <nng/supplemental/http/http.h>
-
-void nng_http_client_connect(nng_http_client *client, nng_aio *aio);
-----
-
-== DESCRIPTION
-
-The `nng_http_client_connect()` starts the process of establishing an HTTP
-connection from _client_ to the server that was indicated in the URL that
-_client_ was configured with.
-
-The result of the operation will be stored in the _aio_ when the operation
-is complete, and will be obtainable via
-xref:nng_aio_result.3.adoc[`nng_aio_result()`].
-
-On success, a pointer to the underlying HTTP client (type `nng_http_conn *`)
-will be stored in the first output result of the _aio_, and can be
-obtained by
-xref:nng_aio_get_output.3.adoc[`nng_aio_get_output()`] with an _index_ of zero (0).
-
-== RETURN VALUES
-
-None.
-
-== ERRORS
-
-[horizontal]
-`NNG_EADDRINVAL`:: The client is configured with an invalid address.
-`NNG_ECANCELED`:: The operation was aborted.
-`NNG_ECONNREFUSED`:: The TCP connection was refused by the server.
-`NNG_ECONNRESET`:: The TCP connection was reset by the server.
-`NNG_ENOMEM`:: Insufficient free memory exists.

-            conn = nng_aio_get_output(aio, 0);
-
-            // ... do something with it here
-
-            // Close the connection when done to avoid leaking it.
