Update IDF to aaf1239 (#1539)
* fix sdmmc config

* Fix warnings in EEPROM

from @Curclamas

* remove leftover TAG in EEPROM

* Initial add of @stickbreaker i2c

* Add log_n

* fix warnings when log is off

* i2c code clean up and reorganization

* add flags to interrupt allocator

* fix sdmmc config

* Fix warnings in EEPROM

from @Curclamas

* remove leftover TAG in EEPROM

* fix errors with latest IDF

* fix debug optimization (#1365)

incorrect optimization for debugging tick markers.

* Fix some missing BT header

* Change BTSerial log calls

* Update BLE lib

* Arduino-ESP32 release management scripted (#1515)

* Calculate an absolute path for a custom partitions table (#1452)

* * Arduino-ESP32 release management scripted
(ready-to-merge)

* * secure env for espressif/arduino-esp32

* * build tests enabled
* gitter webhook enabled

* * gitter room link fixed
* better comment

* * filepaths fixed

* BT Serial adjustments

* * don't run sketch builds & tests for tagged builds

* Return false from WiFi.hostByName() if hostname is not resolved

* Free BT Memory when BT is not used

* WIFI_MODE_NULL is not supported anymore

* Select some key examples to build with PlatformIO to save some time

* Update BLE lib

* Fixed BLE lib

* Major WiFi overhaul

- auto reconnect on connection loss now works
- moved to event groups
- some code clean up and procedure optimizations
- new methods to get a more elaborate system ststus

* Add cmake tests to travis

* Add initial AsyncUDP

* Add NetBIOS lib and fix CMake includes

* Add Initial WebServer

* Fix WebServer and examples

* travis not quiting on build fail

* Try different travis build

* Update IDF to aaf1239

* Fix WPS Example

* fix script permission and add some fail tests to sketch builder

* Add missing space in WiFiClient::write(Stream &stream)
