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_set_method - set HTTP request method
+
+== SYNOPSIS
+
+[source, c]
+----
+#include <nng/nng.h>
+#include <nng/supplemental/http/http.h>
+
+void nng_http_set_method(nng_http *conn, const char *method);
+----
+
+== DESCRIPTION
+
+The `nng_http_set_method()` sets the HTTP method associated with
+the connection _conn_ to _method_.  The _method_ must be a string,
+such as "GET" or "POST".
+
+The default value method for newly allocated requests is "GET".
+
+If the method is longer than 32 bytes, it may be silently truncated.
+(There are no methods defined that are this long.)
+
+The value _method_ is copied, so the caller may dispose of it after
+the call completes.
