More man page reorganization.

Man pages need special handling, and we can have other kinds of documentation
like initial starting guides, etc., which would have different processing
applied.  So lets move them off into their own directory.

+== NAME
+
+nng_http_req_set_header - set HTTP request header
+
+== SYNOPSIS
+
+[source, c]
+-----------
+#include <nng/nng.h>
+#include <nng/supplemental/http/http.h>
+
+int nng_http_req_set_header(nng_http_req *req, const char *key,
+    const char *val);
+-----------
+
+== DESCRIPTION
+
+The `nng_http_req_set_header()` sets the HTTP header for the request
+_req_ and the _key_ to the _val_.  The _key_ and _val_ are copied.
+Any previous header with the same _key_ is replaced.
+
+TIP: See <<nng_http_req_add_header#,nng_http_req_add_header(3)>> to
+add additional headers with the same _key_ without replacing them.
+
+The value of _key_ is case insensitive, and should not include the final
+colon in an HTTP header.  For example, specifying `Host` or `hOSt` are
+equivalent, whereas the value `Host:` is not a legal header key.
+
+== RETURN VALUES
+
+This function returns 0 on success, and non-zero otherwise.
+
+== ERRORS
+
+`NNG_ENOMEM`:: Insufficient memory to perform the operation.
+`NNG_ENOTSUP`:: No support for HTTP in the library.
