Set focus to monitor to ask password if line is multiplexed (Laurent Vivier)

This patch allows to display the "Password:" prompt if we use encrypted
disk with "-nographic" option.

It also modifies management of "-nographic" to not override user's
choices for "-serial", "-parallel" and "-monitor".

When qemu has to ask a password with "-nographic" with a multiplexed
serial interface, it forces the focus to the monitor and restore
original focus after.
