Jumping (currently rebooting, see crosbug.com/p/8100) to the RW image should
be done by vboot_init(), not vboot_pre_init().
As currently written, vboot_init() has to come AFTER these function calls:
task_init(); // sets up interrupts so that uart will work
watchdog_init(1100); // in case we fall over somewhere
uart_init(); // we'd REALLY like to see some debugging output
system_init(); // may go away with crosbug.com/p/8100
keyboard_scan_init(); // check for F3 to go to recovery mode
flash_init(); // maybe set RO regions (this should come earlier!)
eeprom_init(); // this is where the try_b flags are kept

Useful when debugging to determine if a user has an official build or
not, particularly early in the devel process where we're handing
builds to everyone. Particularly useful for proto1, since not all
those systems will be case-open servo-attached.
Also move get-version LPC command into system.c, where it's closer to
the system functions it calls (matches what we do for other host
commands).

The thermal engine monitors the temperature readings from all sensors.
For each sensor, five threshold temperatures can be set:
1. Low fan speed.
2. High fan speed.
3. SMI warning.
4. Shutdown CPU.
5. Shutdown everything we can.
Each of these thresholds can be set to either a fixed value or disabled.
Currently the real implementation of SMI warning and shutting down is
left as TODO, as indicated in the comment.
