If you receive a package with a data length of zero, parsePacket returns 0, but rx_buffer will exist. So if another parsePacket with no read access returns to zeros, there is still data that can be read. This example would not work: https://www.arduino.cc/en/Reference/EthernetUDPParsePacket
Also I added a check if rx_buffer exit when you try to flush it.

* Add missing space in WiFiClient::write(Stream &stream)
* Add `SYSTEM_EVENT_WIFI_READY` call back once wifi service is init. allows you to hook in, as the sdk does not generate this event for you.
As it stands the SDK does not appear to set `WIFI_MODE_NULL` correctly. if the wifi is initialised and set to `WIFI_MODE_NULL` it actually defaults to AP mode. This fix keeps `WIFI_MODE_NULL` within the ESP class if the wifi has not been init yet, and works in my testing. albeit a one sided conversation.

* make changes compatible with new _persistent behaviour.
wifi_err_reason_t doesn't have reason code 12. After reason code 11, we are getting wrong wifi disconnected reason message. Added "UNSPECIFIED" in place of reason code 12.
And above 201 reason code, it should be r-176 instead of r-177. Because messages are started from zeroth offset.
If you develop on windows and need cr/lf files, see this:
https://git-scm.com/book/en/v2/Customizing-Git-Git-Configuration#_formatting_and_whitespace
Git can handle this by auto-converting CRLF line endings into LF
when you add a file to the index, and vice versa when it checks out
code onto your filesystem. You can turn on this functionality with
the core.autocrlf setting. If you're on a Windows machine, set it
to true - this converts LF endings into CRLF when you check out code:
$ git config --global core.autocrlf true
* Update mDNS and LEDC
* update toolchain
* Update IDF to 1c3dd23
* Advertise the board variant for Arduino OTA
* Add generic variant definition for mDNS
* Allow configuration of Ethernet PHY clock source
Refer to https://github.com/espressif/esp-idf/pull/1127
The internal APLL can be used to generate the 50MHz clock for the internal EMAC and the external Ethernet PHY.
The clock can either be input on GPIO0 (as before) or output on GPIO0, GPIO16 or GPIO17 (only GPIO17 extensively tested).
New example available.

* Change disconnect function
Current implementation does not disconnect the WiFi. Use of `esp_wifi_disconnect()` does.
* Update WiFiSTA.cpp
put back the clear ssid + password
remove the duplicate `esp_wifi_set_config(WIFI_IF_STA, &conf);`
send() can return a value > 0 but less than size indicating it was able to accept some of the data in buffer. The caller must try again after updating the buffer pointer and size remaining.
* Update WiFiAP.cpp
set from code the maximum number of clients to smaller than 4 (in my case i must allow only one client at a time)
* Update WiFiAP.h
* Update WiFiAP.cpp
* Update WiFiAP.cpp
* Create WiFiAP.cpp
