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_req_add_header - add HTTP request header
-
-== SYNOPSIS
-
-[source, c]
-----
-#include <nng/nng.h>
-#include <nng/supplemental/http/http.h>
-
-int nng_http_req_add_header(nng_http_req *req, const char *key,
-    const char *val);
-----
-
-== DESCRIPTION
-
-The `nng_http_req_add_header()` adds an HTTP header for the request
-_req_ and the _key_ to the _val_.  The _key_ and _val_ are copied.
-
-If a header with the value of _key_ already exists, then a comma
-and whitespace separate are appended to it, followed by _val_.
-
-If no such header already exists, then one is created with the value _val_.
-
-TIP: The HTTP specification requires that duplicate headers be treated
-identically to a single header with multiple comma-delimited values.
-
-TIP: See xref:nng_http_req_set_header.3http.adoc[`nng_http_req_set_header()`] if
-replacement of an existing header rather than appending to it is desired.
-
-The value of _key_ is case insensitive, and should not include the final
-colon in an HTTP header.
-For example, specifying `Host` or `hOSt` are
-equivalent, whereas the value `Host:` is not a legal header key.
-
-== RETURN VALUES
-
-This function returns 0 on success, and non-zero otherwise.
-
-== ERRORS
-
-[horizontal]
-`NNG_ENOMEM`:: Insufficient memory to perform the operation.
-`NNG_ENOTSUP`:: No support for HTTP in the library.
