TEST=if timestamps show up in the debug output, it works

The previous TX might end in the middle of the buffer filling and stop
TX. So we need to check if we want to restart the transmission.
With 1-byte deep FIFO, it's easy to trigger that race condition.

TEST=run console commands with lots of traces on BDS, Link and ADV and check
we are not stuck.

If the last command is saved at the beginning of the buffer, loading
this command will lead to a character missing.

Record commands used previously and use up/down arrow key to navigate in
the command history.
Also removed the command '.' of repeating last command as we can use up
arrow key now.
Also changed the behaviour of uart_write_char() to be blocking on
transmit FIFO full, so that we do not lose echoed character and do not
need to flush.

TEST=Type 'help' and enter. Then type 'aaaa' and up arrow key, should
show 'help', and pressing enter prints help.
Type 'hellp' and enter. Then type 'aaaaaa' and up arrow key, should show
'hellp'. Should be able to use left/right arrow key and backspace to
correct it to 'help', and pressing enter prints help.
Type 'help' and enter. Then type 'aaa', up arrow key, and down arrow
key. Should show 'aaa'.

Handle left and right arrow key to move cursor around.
Other escape sequences are still ignored.
BUG=chrome-os-partner:7865
TEST=type some text and use left and right arrow key. Cursor should
move.
type 'hellp', left key, and backspace. Should show 'help' and hitting
enter prints help.
type 'hexp', left key, backspace, 'l'. Should show 'help and hitting
enter prints help.

I keep hitting the darn arrow keys. Until we can do something more
elegant like a real command history, this will at least keep me from
corrupting the display and input buffer.

TEST=type 'help' and some arrow keys, then enter. Should print help, not an error.

Preparatory work to introduce a second SoC : 3rd series 1/2
Most of the code is handling the buffering and the printf, thus put it
in an hardware independant location and only implement the UART
dependant portions in the chip driver.

BUG=None
TEST=run on BDS and stress the console.
