cmd: bdinfo: Optionally use getopt and implement bdinfo -a

Add optional support for getopt() and in case this is enabled via
GETOPT configuration option, implement support for 'bdinfo -a'.
The 'bdinfo -a' behaves exactly like bdinfo and prints 'all' the
bdinfo information. This is implemented in preparation for other
more fine-grained options.
