cmd: Add accessor functions for options
Add a load of accessor functions to help with pulling values out
from the the cmd_syndesc structure. The idea here is to make it
simpler to manipulate command line values, as well as starting to
hide the structure of the cmd_syndesc structure from callers, with
a view to eventually making it private to the cmd library.
