Subject: inets: httpd - Add chunk handling of client data

If the client uses PUT or POST to send a HTTP body the server
currently will gather the whole body in memory before passing it on to
the mod-callback. For legacy reasons it also converts the binary body
to a list, this is really bad for memory usage!

Add new option max_client_body_chunk to enable chunked handling of
content-length requests. Also make it possible for chunked-encoded data
to be propagated in portions to the mod-callback.
