- fix typo - replace emsaurt_tx_poll by emsuart_tx_poll - smart tx - enabled by EMS_Sys_Status.emsTxDelay == 2 use loopback to send in burst mode - change emsuart_tx_poll to use emsuart_tx_buffer - encapsulate uart_swap in #ifndef NO_UART_SWAP (private use)

Add Smart-Tx function
What Smart-Tx does:
Characters are send in loopback mode, w/o any delay. Waits until the send char (incl. ) is received. After the whole telegram is send out we expect to receive the whole telegram echo from EMS busmaster.
Because we monitor the send chars via loopback, we can precisely determine the required length for a w/o creating 'ghost characters'.
Smart-Tx is enabled by setting EMS_Sys_Status.emsTxDelay to 2. All other values will keep the old behaviour. So a non-intrusive switch should be possible.
