Relax inter-CTU dependencies when SAO is off
...
When using WPP and OWF, the first CTU of a row depends on the last CTU
of the row below in the reference frame. This is necessary when SAO is
enabled since we currently do SAO for a whole CTU row at a time. When
SAO is disabled, however, it is unnecessary to wait for the whole row.
Changes CTUs to depend only on the CTU below in the reference frame
instead of the whole row when WPP and OWF are enabled and SAO disabled.
Gives a significant speedup when running on a machine with many CPU
cores.

Copy the kvz_config passed to encoder_open
...
The kvz_config struct is created by the user but kvazaar keeps a pointer
to it. It is easy to break things by modifying the configuration outside
kvazaar. In addition, kvazaar modifies the struct even though it is has
a const modifier.
This commit changes the field cfg in encoder_control_t to be a copy of
the kvz_config struct instead of a pointer, removing modifications to
the const struct and allowing users to do whatever they want with it
after opening the encoder.

Fix inter bipred search
...
When the number of merge candidates was five, biprediction search would
read past the bounds of the priority list arrays. Fixed to limit the
search to the first four candidates.

Fix inter search for small SMP and AMP blocks
...
The function search_pu_inter_ref incorrectly rounded the coordinates of
the block to down to a multiple 8 pixels. Small SMP and AMP blocks may
start at coordinates that are not multiples of 8. Fixed by removing the
rounding.
Fixes a failing assert when --mv-constraint is used with --smp or --amp.

Fix bug in --mv-constraint
...
Subpixel motion estimation return 0-vector when no subpixel vector is
within the constraint. Fix is to not call subpixel motion estimation
when the integer vector is not within the constraint.

Clean up code using the fixed point frac bit tables
...
This is to prepare for changing the code using the floating point table
to use the fixed point table instead.
This also allows reducing the size of the fractional part, which was
useful for finding every place where the the fixed point presentation
is relied upon.

Use separate lambda and QP for each LCU

Adds fields lambda, lambda_sqrt and qp to encoder_state_t. Drops field
cur_lambda_cost_sqrt from encoder_state_config_frame_t and renames
cur_lambda_cost to lambda.

Arrange the decision tree such that there is only 3 branches on the

Improve fast mvd coding cost estimation
...
A lot of time is being taken up by this function on ultrafast, and it
doesn't do a very good job. This change aims to both simplify the
logic and make the estimate better.
The logic is simplified by using a look up for the step mvd bit cost
step function instead of mimicking the binarization process. The
estimation is made better by checking fractional cabac bit costs.
The new function returns the same results as
kvz_get_mvd_coding_cost_cabac, but is also faster than the old
function.

Rename encoder_state_t.global to frame

"Frame" is more accurate than "global" since when OWF is used, encoder
states for each frame have their own struct.
