helper/command: add macro CMD 

Accessing the variable "cmd" in a COMMAND_HANDLER is confusing
because the variable definition is not visible in the prototype,
thus "cmd" can be identified by the reader as a global variable
defined somewhere else.

Add the new macro CMD to make more evident it is a part of the
COMMAND_HANDLER.
