websocket used to receive events.

Changes:
* Added utilities to http.c:
* ast_get_http_method_from_string().
* ast_http_parse_post_form().
* Added utilities to json.c:
* ast_json_nvp_array_to_ast_variables().
* ast_variables_to_json_nvp_array().
* Added definitions for new events to carry REST responses.
* Created res/ari/ari_websocket_requests.c to house the new request handlers.
* Moved non-event specific code out of res/ari/resource_events.c into
res/ari/ari_websockets.c
* Refactored res/res_ari.c to move non-http code out of ast_ari_callback()
(which is http specific) and into ast_ari_invoke() so it can be shared
between both the http and websocket transports.
