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_conn_write_res - write HTTP response
-
-== SYNOPSIS
-
-[source, c]
-----
-#include <nng/nng.h>
-#include <nng/supplemental/http/http.h>
-
-void nng_http_conn_write_res(nng_http_conn *conn, nng_aio *aio);
-----
-
-== DESCRIPTION
-
-The `nng_http_conn_write_res()` function starts an asynchronous write of
-the HTTP response associated with the connection _conn_.
-The entire response is sent,
-including headers, and if present, the response body data.
-(The response body can be set with
-xref:nng_http_res_set_data.3http.adoc[`nng_http_res_set_data()`] or
-xref:nng_http_res_copy_data.3http.adoc[`nng_http_res_copy_data()`].)
-
-This function returns immediately, with no return value.
-Completion of the operation is signaled via the _aio_, and the final result
-may be obtained via xref:nng_aio_result.3.adoc[`nng_aio_result()`].
-That result will either be zero or an error code.
-
-=== Persistent Connections
-
-By default, for `HTTP/1.1` connections, the connection is kept open, and
-will be reused to receive new requests.
-
-If however the _res_ contains a header of `Connection:` with a value
-of `Close` (case-insensitive) or the response corresponds to `HTTP/1.0`,
-then the connection is immediately after sending the response.
-
-NOTE: Consider using the
-xref:nng_http_client_transact.3http.adoc[`nng_http_client_transact()`] or
-xref:nng_http_conn_transact.3http.adoc[`nng_http_conn_transact()`] functions,
-which provide a simpler interface for performing a complete HTTP client
-transaction.
-
-== RETURN VALUES
-
-None.
-
-== ERRORS
-
-[horizontal]
-`NNG_ECANCELED`:: The operation was canceled.
-`NNG_ECLOSED`:: The connection was closed.
-`NNG_ECONNRESET`:: The peer closed the connection.
-`NNG_ENOMEM`:: Insufficient free memory to perform the operation.
-`NNG_ENOTSUP`:: HTTP operations are not supported.
-`NNG_ETIMEDOUT`:: Timeout waiting for data from the connection.
