Right now magicvars is just a compile time generated array of struct
magicvar. We could add a const char *description argument to the
dev_add_param_* functions for adding the descriptions to the parameters.

You can get the available parameters for a device with 'devinfo
<devname>', but currently there is no way to see all available
parameters for all devices. Also there can be no description attached
to a parameter. Adding this would indeed be valuable.
