* 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.
fixes#48
This commit removes the usage of all legacy FreeRTOS data types that
are exposed via configENABLE_BACKWARD_COMPATIBILITY. Legacy types can
still be used by enabling CONFIG_FREERTOS_ENABLE_BACKWARD_COMPATIBILITY.
* Original commit: espressif/esp-idf@57fd78f5ba
In esp_http_client and esp_websocket_client components, esp_transport_tcp_set_keep_alive has been called and keep-alive config has been saved in ssl->cfg.keep_alive_cfg,
So no need to call esp_transport_ssl_set_keep_alive again.
* Original commit: espressif/esp-idf@c79a907e4f
To be in line with other code and mainly to support base/foundation transport used by both tcp and ssl transport layers
* Original commit: espressif/esp-idf@99805d880f
Client could choose if they want to receive control packets and handle
them.
* If disabled (default) the transport itself tries to handle PING
and CLOSE frames automatically during read operation. If handled
correctly, read outputs 0 indicating no (actual app) data received.
* if enabled, all control frames are passed to the application to be
processed there.

* Original commit: espressif/esp-idf@acc7bd2ca4
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
1. will post twice disconnect event when read error
2. will block `timeout` times when set disable_auto_connect
3. When `esp_websocket_client_stop` before `esp_websocket_client_send*`,
if the `esp_websocket_client_send*` fails, the status will change to
'WEBSOCKET_STATE_WAIT_TIMEOUT', and the next `esp_websocket_client_start` will fail forever
* Original commit: espressif/esp-idf@341e480573
Previous implementation violated the RFC by having both the actual opcode and WS_FIN flag set for all fragments of a message.
Fixed by setting the opcode only for the first fragment and WS_FIN for the last one
Closes IDFGH-2938
Closes https://github.com/espressif/esp-idf/issues/4974
* Original commit: espressif/esp-idf@14992e62c5
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
* Original commit: espressif/esp-idf@ffeda3003c
user_context was missing from websocket event data, added. Also added the websocket client handle to the event data.
Removed unused event data struct.
