x86: Streamline the CPU early boot process.
Mainly this involves getting rid of a bunch of cpumasks and replacing
with a single 'cpu_state' enumeration to track progress and allow
master-slave handshaking.
Cleaning this stuff up is a prerequisite for safely handling slave
failure (e.g., out of memory, invalid slave CPU capabilities,
...). This will get fixed up in a future patch.
