Removed option to run REPL in separate thread

  the option was introduced to resolve some issues
  which was fixed later, so it is not needed anymore

Refactored I2C slave support
  much improved i2c slave operation

Added 'machine.RFCOMM' module
  support for Bluetooth classic SPP profile
  functionality equivalent to that of the UART module
  Works only on boards with external SPI_RAM

Added 'highspeed' option when configuring SDCard in SPI mode

Updated 'machine' module
  fixed bug in 'machine.stdin_disable()' function
  added 'machine.WDT()' function

Updated 'machine.ADC' module
  arg name '8bit' changed to 'byte' in read_timed() function

Updated 'network' module
  station's rssi is reported in 'status('stations')' function

Updated 'curl' module
  fixed param parsing in curl.post() function

Updated 'mdns' module
  fixed param parsing in addService() function

'esp-idf' updated
     date: 2018-06-27
  version: v3.1-beta1-14-g698d3baf
     hash: 698d3bafa51a06a89605c6a15f89df514efa21f8
