add more command_handler conversion macros

Browse Source 
Add additional macros to allow command handling to be migrated easily:
CMD_CTX, CMD_ARGC, and CMD_ARGV.  Updates CMD_NAME to use CMD_ARGV.

In addition to making the remaining patches of this series cleaner,
this introduces easily sed-able symbols that could allow us to retire
these once the command handler infrastructure matures (i.e. pre-1.0).
