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

  arbitrary size.
- Fixes computation of QP predictors so that it works for quantization
  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.

Arttu Ylä-Outinen 6ce2fb1238 Add pixel offsets to encoder_state_config_tile_t 
Adds fields offset_x and offset_y to encoder_state_config_tile_t.

Arttu Ylä-Outinen 2380ba0d41 Reduce copying in kvz_get_coeff_cost 
Changes function kvz_get_coeff_cost to only copy the CABAC contexts and
not the whole encoder state.

Other threads could be simultaneously using the other parts of the
encoder state. Only copying the CABAC fixes a TSan data race warning.
