reworks because of 'tx_mode 2' and protocol issues

Browse Source 
° added markers (GIO12, GPIO14) for logic analyzer debugging

° change UART initialisation
  - set RxFIFO full to 1 char, so we can detect active telegram on EMS-Bus
  - set RxTOT to 1 char for the same reason

° in ems_parseTelegram: ignore telegram if  emsRxStatus != EMS_RX_STATUS_IDLE
  because we missed to respond in a timely manner

° ems_tx_buffer is not void anymore, instead we return the Tx status
° extended the emsTxStatus
  - EMS_TX_WTD_TIMEOUT: timeout while waiting for echo of last Tx byte
    out telegram was ignored by the bus master, so the byte wasn't echoed
  - EMS_TX_BRK_DETECT:  BRK detected while sending the telegram
    bus master send us a break because of protocol violation

° add burnStarts, burnWorkMin and heatWorkMin to MQTT boiler message

TODO:
  + take care of ems_tx_buffer return code
  + accept direct telegram in ems_parse_telegram and do a proper acknowledge
  + split the heartbeat in static (version, IP-address) and dynamic (RSS etc)
  + change the hearbeat to a JSON structure so we can easier pick the uptime
