Log Message:
Make awaitkey() poll once even if the timeout is 0.  This also fixes a problem
where a keypress within the last polling interval would not be noticed.
Add a new function, conisshift(), which is used to detect whether a shift key
is pressed.  Use this via awaitkey() to allow interrupting the boot by holding
down shift (similar to LILO).

This allows setting the timeout to 0 and still being able to use the boot
program.
