Updated 'ethernet' module

  updated all modules using network to work on any network interface, including ethernet
  ftpserver and telnet server now also works over ethernet

Updated 'uos.sdconfig()'
  SPI host can be selected if SDCard mode is SPI

Updated 'Curl' module
  added 'getmail' method
  added option to set maximum write buffer size, lower size can make it more usable on boards without psRAM
  tab character (0x09) is now accepted in response body

Updated 'machine' module
  fixed bug in 'deepsleep' method, deepslep for all timeout values now works as expected

Updated 'DAC' module
  fixed bug in 'waveform' method, the 'duration' argument now works for waveform types

Updated 'machine.Pin' module
  fixed bug in handling the 'debounce' argument

Added 'requests' module implemented in C, based on 'esp_http_client' componnent
  get, post, head, put, patch methods

Refactored 'display' module
  added full support for FTDI EVE chips (FT8xx)
  prepared for implementation of e-paper displays support

Updated sdcard support

Updated esp-idf to version v3.1-rc1-53509c7b
