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_res_alloc_error - allocate HTTP error response
-
-== SYNOPSIS
-
-[source, c]
-----
-#include <nng/nng.h>
-#include <nng/supplemental/http/http.h>
-
-int nng_http_res_alloc_error(nng_http_res **resp, uint16_t status);
-----
-
-== DESCRIPTION
-
-The `nng_http_res_alloc_error()` function allocates a new HTTP response structure
-and stores a pointer to it in __resp__.
-The response will be initialized
-with the status code _status_, a corresponding reason phrase, and
-a simple HTML page containing the same information will be generated and
-attached to the response.
-(Relevant HTTP headers will be set as well, such as `Content-Type`
-and `Content-Length`.)
-The HTTP protocol version is also set to "HTTP/1.1".
-
-TIP: This is the simplest way to generate an error response.
-
-== RETURN VALUES
-
-This function returns 0 on success, and non-zero otherwise.
-
-== ERRORS
-
-[horizontal]
-`NNG_ENOMEM`:: Insufficient free memory exists to allocate a message.
-`NNG_ENOTSUP`:: HTTP support not configured.
