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_copy_data - copy HTTP request body
-
-== SYNOPSIS
-
-[source, c]
-----
-#include <nng/nng.h>
-#include <nng/supplemental/http/http.h>
-
-int nng_http_req_copy_data(nng_http_req *req, const void *body, size_t size);
-----
-
-== DESCRIPTION
-
-The `nng_http_req_copy_data()` makes a copy of _body_ (of size __size__)
-and sets the HTTP body for the request _req_ to it.
-The copy will be deallocated automatically when _req_ is freed.
-
-The copied body data will be automatically sent with the request when it
-is sent using xref:nng_http_conn_write_req.3http.adoc[`nng_http_conn_write_req()`].
-
-This also updates the relevant `Content-Length` header of _req_.
-
-NOTE: The current framework does not support sending data via chunked
-transfer-encoding.
-
-TIP: To avoid copying data, the
-xref:nng_http_req_set_data.3http.adoc[`nng_http_req_set_data()`] may be used instead.
-
-TIP: It is a good idea to also set the `Content-Type` header.
-
-== 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.
