Partial fix for media instance. (It was using input_control_e intead of

input_query_e).

Btw input_internal.h is an internal header for src/input/* ONLY.
If input/control/* need it, then it is BROKEN (or there is a missing
functionnality, just ask for it then)
 I see it calling demux2_Control, this will segfault if you are unlucky.
 Accessing directly to p_input->p member is also forbidden.
