  [arch/linux] start replacing uart_event with thread

While it should not really happen, it is still possible that a uart_transmit 
was interrupted and data should be written from the uart_handler.
This needs to be fixed.

totally untested...

  [arch/linux] uart: thread only handles receiving data

uart_transmit should always be able to directly write the single byte to the 
serial device.
So there should be no need to use the tx queue.

Since the uart threads calls select on the fds to check when there is something 
to read,
it will not wake up if there is data in the tx buffer...

Using the tx buffer was previously done because the system timer was generating 
signals and interrupted the write.
Since this is no longer the case it should be fine like this.

Seems to work fine on the bebop and beagle bone black.
