We need to make sure that the entries in vars are in the same order, so
use 

  	[DIRECT_ID] = { DIRECT, .u.n = {NULL, 0, 0, 1, 0, 0, NULL } },

etc. to make sure that the indexes are correct. Also add NB_ID as last
member of the enum, and use it for the "vars" array length, so we're
sure we're not missing anything.

Not all vars make sense as parameters: caps_start, caps_stop and pause
are not actually tunable, so don't add a parameter for them.
