console: Make die() and friends variadic
die() currently only accepts a fixed message string, which is rather
inconvenient when there is extra information that would be helpful to
print in the error message. This currently requires an extra call to
printk(), which is somewhat awkward:
printk(BIOS_EMERG, "Bad table, opcode %d at %d", id, i);
die(""); // what do I say here?
die() already has a printk() inside it to print the error message, so
let's just make it variadic to combine the two.
die("Bad table, opcode %d at %d", id, i); // much better
Forwarding variadic arguments from one function to another is rather
tricky, so die_with_post_code() is redefined as a variadic macro
instead.
