Serial console resizing

Unlike ssh, serial consoles like virsh console don’t receive SIGWINCH and so instead of resizing they stay stuck at 80x24, making line wrapping, tab completion, curses and reading in a pager difficult.

So get the terminal size from the outside bash shell, and set the same values manually within the serial console:

host$ echo $LINES $COLUMNS
182 92
host$ sudo virsh console guest
guest$ stty rows 182 cols 92
