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. Conflicts: lib/inets/test/httpd_SUITE.erl
