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_read_all - read all from HTTP connection
-
-== SYNOPSIS
-
-[source, c]
-----
-#include <nng/nng.h>
-#include <nng/supplemental/http/http.h>
-
-void nng_http_conn_read_all(nng_http_conn *conn, nng_aio *aio);
-----
-
-== DESCRIPTION
-
-The `nng_http_conn_read_all()` function starts an asynchronous read from the
-HTTP connection _conn_, into 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 only when the entire amount of data
-requested has been read, or an error has occurred.
-If the operation
-completes successfully, then the entire requested data has been read.
-
-It is still possible for a partial read to complete in the event of an error.
-The actual number of bytes read can be determined with
-xref:nng_aio_count.3.adoc[`nng_aio_count()`].
-
-TIP: The main purpose for this function is to facilitate reading HTTP
-body content, after first determining the length of the body content
-from the relevant HTTP headers (typically `Content-Length`).
-
-== 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.
