* Update BLE lib
* Update IDF to f586f5e
* Restructure Bluetooth Serial includes
* Update esptool and gen_esp32part
* Add partition scheme selection for menuconfig
* Add partition scheme selection for Arduino IDE
* Fix BLE example
* Second attempt BLE fix
* Add exceptions to PIO
* Update mDNS and LEDC
* update toolchain
* Update IDF to 1c3dd23
* Advertise the board variant for Arduino OTA
* Add generic variant definition for mDNS
With this step we remove all dependencies, but git. Mac and Linux come
with Python by default, so they will keep using get.py to update the
toolchain and support binaries. Windows users have an "All point and
click" installation option that requires only git and Arduino to be
downloaded.
Fingers crossed :)
