Merge branch 'master' into ESP8266

* master:
  millis() is 64-bits on the Arduino/Genuino 101
  CLOCK_SPEED is now correctly defined as an int instead of a double
  Define CLOCK_SPEED as type int
  Add genuino101 to travis, remove call to setClockDivider (obsolete)
  Remove duplicate code
  Add Arduino 101 mods from https://github.com/KitPan/USB_Host_Shield_2.0
