esp_netif_init() returns standard esp_err_t error code (unlike tcpip_adapter init), so shall be checked for the return value
Also to make the initialization code more consistent.
Removed all other instances of call to esp_wifi_init(), because every time this is called it
will override its previously set default event handler and hence cause numerous warnings.
Also, call nvs_flash_init() only once, that is before calling esp_wifi_init() in main function
Note : Examples have been updated to prevent invocation of bluedroid/wifi APIs from inside timer callback when stopping provisioning. Workaround is to spawn new task from inside the timer callback.
* BLE and softAP provisioning examples added along with tests.
* An application specific example added for demonstrating custom provisioning scheme.
* tools/esp_prov/esp_prov.py can be used as a provisioning client for SoftAP, BLE and CLI based transports.
