Inconsistency is known, and I don't know if fixing it will help us in
the future since option/parameter are somewhat stretchable definitions.

Thanks for your review! New patch follows for reference.
Committed in r1483.
--mainboard is a relic from a time before external programmers and makes
the CLI inconsistent.
Use a programmer parameter instead and free up the short option -m.
NOTE:
The --list-supported-wiki output changed to use -p internal:mainboard=
instead of -m
The --list-supported output changed the heading of the mainboard list from
Vendor Board Status Required option
to
Vendor Board Status Required value for
-p internal:mainboard=
Fix lb_vendor_dev_from_string() not to write to the supplied string.
