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 - write to HTTP connection
-
-== SYNOPSIS
-
-[source, c]
-----
-#include <nng/nng.h>
-#include <nng/supplemental/http/http.h>
-
-void nng_http_conn_write(nng_http_conn *conn, nng_aio *aio);
-----
-
-== DESCRIPTION
-
-The `nng_http_conn_write()` function starts an asynchronous write to the
-HTTP connection _conn_ from the scatter/gather vector located in the
-asynchronous I/O structure _aio_.
-
-NOTE: The xref:nng_aio_set_iov.3.adoc[`nng_aio_set_iov()`] function must have been
-called first, to set the scatter/gather vector for _aio_.
-
-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.
-
-The I/O operation completes as soon as at least one byte has been
-written, or an error has occurred.
-Therefore, the number of bytes written may be less than requested.
-The actual number of bytes written can be determined with
-xref:nng_aio_count.3.adoc[`nng_aio_count()`].
-
-TIP: This function is intended to facilitate uses cases that involve changing
-the protocol from HTTP, such as WebSocket.
-Most applications will never need to use this function.
-
-== 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_EINVAL`:: The _aio_ does not contain a valid scatter/gather vector.
-`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.
