Log Message:
Pull up revision 1.38 (requested by drochner in ticket #156):
Implement a "security" command with subcommands to query the status of
the "security" extension and to "freeze" it. With the security extension
frozen, disk passwords cannot be set anymore, until the next hard reset.
Normally, this is the business of the BIOS, but older/buggy/embedded
BIOSes don't care. This leaves the (theoretical) possibility that a
malicious program in posession of superuser rights sets a disk password,
rendering the disk useless (or at least uneconomical to recover from).
Inspired by an article in the german "ct" magazine.
Being here, consolidate the implementations of IDENTIFY into one, and
fix an obvious alignment problem.
