Randall Spangler e74e60c465 Refactor host command interface to support version 3 packets ...

This will fix EC flash commands on pit, once the host side (u-boot and
cros_ec driver) are upgraded to match.

This change is backwards-compatible the EC still supports the existing
version 2 protocols for talking to existing AP/kernel/ectool.

Once the AP-side supports version 3 for SPI (and existing systems are
upgraded), we will remove older SPI support since we haven't shipped a
product which uses SPI.

BUG=chrome-os-partner:20257
BRANCH=none
TEST=disable cros_ec driver support in ectool; 'ectool hello' works on link
    And with an old ectool which predates this CL, 'ectool hello' also works.
    On pit, from u-boot prompt, 'crosec test' and 'crosec version' work, and
    keyboard works.
