Arttu Ylä-Outinen a343f6d587 Prepare for delta QPs at CU-level 
- Replaces lcu_dqp_enabled with max_qp_delta_depth in encoder_control_t.

  groups of arbitrary size.

Arttu Ylä-Outinen fb462b25ef Fix transform skip for inter 
The transform skip flag in cu_info_t was stored under the intra
substruct even though transform skip can be used for inter as well. This
caused bitstream errors. Fixed by moving the flag out of the substruct.
