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. BUG=chrome-os-partner:7815 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'. Change-Id: I65c615d61bf63acb31bea329aa91a3202d4db0ad
