This adds an optional string argument to console_countdown() which can
hold a list of keys which also abort the countdown.

The getchar() call may return an error reported as a -1, e.g. when the
console detects a RATP message and switches to RATP mode.
In general it probably is a good idea to ignore these errors in the
console countdown operation; and in particular for the RATP usecase,
this also prevents from interfering with the countdown and menu just
when switching one of the consoles to RATP mode.
As a hint, this is what the standard console was printing due to this
issue when the RATP console was activated:
Hit m for menu or any other key to stop autoboot: [: missing `]'

This patch makes it possible to abort a console countdown by an external
command, for example when fastboot is used. This requires additional
modifications in the external commands, a call to "console_countdown_abort()"
has to be inserted.

This patch increases the displayed width of the countdown to 4 digits,
otherwise waiting for more then 99 seconds doesn't look good.

The function we have implemented as getc has the semantics of the
standard function getchar, so rename it accorgingly.

This patch factors out the wait-for-key-press loop from the shell command
"timeout" into a sparate file, so that it can be used from C, too.
