- Replaces lcu_dqp_enabled with max_qp_delta_depth in encoder_control_t.
- Fixes set_cu_qps so that it can handle quantization groups of
arbitrary size.
- Fixes computation of QP predictors so that it works for quantization
groups of arbitrary size.
Changes asserts on the reference count of objects to assert the value
after KVZ_ATOMIC_INC instead of directly checking the value. Fixes some
data races detected by TSan.
- Adds missing default values.
- Adds help for --crypto and --key.
- Adds help for --rd=3.
- Adds help for --sao options.
- Some changes to help wording.
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.
cryptopp in version 6.1.0 added a pkg config file which is named libcryptopp.pc
so search also for this name in addition to cryptopp and libcrypto++

Adds an additional grid search step that starts from the zero motion
vector after the normal grid search. The search range for this step is
half of the normal range.
- Changes TZ grid search and star refinement to keep the origin constant
instead of moving to the best position after each iteration.
- Changes star refinement to loop until there is no more improvement,
instead of running the step only once.
When the starting point for integer motion estimation was selected among
the merge candidates, the candidate motion vectors were always rounded
down. This commit changes the rounding so that they are rounded to the
nearest integer MV instead.
Changes reference index list creation so that the negative references
are added to L1 in addition to L0 when biprediction is enabled and no
reordering of pictures is done. Biprediction can now be used with the
low-delay GOP structure.
Changes the crypto module to use unsigned char instead of byte. The byte
typedef is no longer included in the global namespace in crypto++ 6.0.0.
See https://github.com/weidai11/cryptopp/issues/442.
Fixes#184.
