- 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.

Fixes#184.
Checks the cost of flushing all coefficients of an inter block to zero.
This is much faster than doing full RDOQ but can still reduce bitrate
significantly. Encoding speed is increased since fewer coefficient bits
have to be coded with CABAC.
Moves duplicate code for writing the MVD of a single motion vector from
kvz_get_mvd_coding_cost_cabac and encoder_inter_prediction_unit to a new
function.
SMP/AMP search is performed using a lower work tree level than the
normal inter search so the prediction info must be copied up if an
SMP/AMP mode is chosen. Previously pixels and coefficient were copied as
well. Changed to only copy prediction info.
