This unifies all the EC header files to use __CROS_EC_FILENAME_H
as the include guard. Well, except for test/ util/ and extra/
which use __TEST_ __UTIL_ and __EXTRA_ prefixes respectively.

This adds a new host commmand for sending RW updates to PD devices.
The host command has a variety of sub-commands for performing the
update, including: erase RW, reboot, write new hash, write flash.
To program zinger RW, you should send host commands in this order:
write new hash to all 0's
reboot (zinger boots into RO since RW hash doesn't match)
erase RW
write flash
write new hash to match contents of RW
reboot
This also adds an ectool command to write a new RW. Just pass it
the RW .flat or .bin file.

Imported code from VBoot firmware cryptolib and slightly reformat it for
the EC code base.
We already have SHA-256, but for updates over PD, the maximum payload
size is 192 bits, so SHA-1 seems a better trade-off.
