Rather than go through the task queue, host_command_process() processes
the command immediately, has all of its required state passed in,
allowing the caller complete control of the buffers.

build and boot on link, see that messages are stil processed
build and boot on snow, which uses this new command

This seems to be a hangover from the LPC protocol. We can send a result
just by sending a response with no data.
Drop this function and remove all uses of it.
Also use 'enum ec_status' instead of int, since this is the correct
response type.

Preparatory work to use common host command code between ARM and x86.
Just rename constants, do not change the binary API.

Preparatory work to use common host command code between ARM and x86.
Every command sends back explicitly the size of the response payload.
The size of the response defaults to 0 ond can be updated.
Add a protocol version number returned as command 0x00 to help with
backward compatibility.
move a couple of function from lpc specific header to host commands to
be able to implement them for the I2C link.
