* Error handling improved to show status code from server
* Added new API `esp_websocket_client_set_headers`
* Dispatches 'WEBSOCKET_EVENT_BEFORE_CONNECT' event before tcp connection
with esp_transport_ssl_crt_bundle_attach(), it is not necessary to
include a specific certificate. other protocol clients, such as
esp_http_client, do the same.

Internal tcp_transport functions could now use custom socket operations.
This is used for WebSocket transport, when we typically wait for clean
connection closure, i.e. selecting for read/error with expected errno or
recv size=0 while socket readable (=connection terminated by FIN flag)
* Original commit: espressif/esp-idf@5e9f8b52e7
transport_ws can now be read multiple times in a row to read frames larger than the buffer.
Added reporting of total payload length and offset to the user in websocket_client.
Added local example test for long messages.
Closes IDF-1083

Removed unused event data struct.
Closes: IDF-1271
* Original commit: espressif/esp-idf@7c0e3765ec
tcp-transport component did not support wait forever. this update uses value of -1 to request this state.
websocket client uses timeouts in RTOS ticks. fixed recalculation to ms (including special value of -1) to use correctly tcp-transport component
