Add negative references to L1 list

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

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.

Add monochrome encoding

Write bitstream without chroma when encoding with --input-format=P400.
This reduces bitstream size by 0-1 %, compared to coding monochrome in
420 format, and speeds up encoding slightly due to not processing
chroma.
