Arttu Ylä-Outinen f5eef7f33c Use luma pixel coordinates in encode_coding_tree
Changes functions encode_intra_coding_unit and encode_coding_tree to
take coordinate arguments in units of luma pixels instead of 8 px
blocks. This should make the code easier to understand.

Arttu Ylä-Outinen 525a5180ff Combine intra CU encoding functions
Merges functions encode_intra_coding_unit and
encode_intra_coding_unit_encry. Removes a lot of duplicated code.

Arttu Ylä-Outinen 610c91b0c5 Use luma pixel coordinates in TU coding functions
Changes functions encode_transform_unit and encode_transform_coeff to
take coordinate arguments in units of luma pixels instead of 4 px
blocks. This should make the code easier to understand.

Arttu Ylä-Outinen 2f2c281e8e Fix a memory leak in crypto
A CryptoPP::CFB_Mode<CryptoPP::AES>::Encryption was allocated at the
beginning of encoder_state_encode_leaf and was never freed. This commit
changes encoder_state_worker_encode_lcu to delete the CFB_Mode. Also
moves crypto handle from encoder_state_config_tile_t to encoder_state_t
so that it can be safely deleted without affecting other threads in the
same tile.

Arttu Ylä-Outinen 6829865190 Fix inline declaration in intra_mode_encryption
Moves the inline declaration of intra_mode_encryption before the type
and changes it to use the INLINE macro. Inline declaration after type
triggered a warning on GCC.

Arttu Ylä-Outinen 95775a1645 Change coefficient storage order
Changes coefficient storage order to a zig-zag order. Reduces
unnecessary copying of coefficients to temporary arrays.

Arttu Ylä-Outinen 1357dd0599 Pass coeffs through encoder state
Changes the way coefficients are passed from kvz_search_lcu to
kvz_encode_coding_tree. Drops fields coeff_y, coeff_u and coeff_v in
videoframe_t and instead passes them through field coeff in
endoder_state_t.

Arttu Ylä-Outinen df359b8f95 Fix indentation in encode_coding_tree.c
Fixes indentation of a for loop that was causing a misleading
indentation warning on GCC.

Fixes #163.

Arttu Ylä-Outinen 51786eda67 Drop redundant fields in encoder_control_t
Some of the fields in encoder_control_t were simply copies of the
corresponding fields in kvz_config. This commit drops the copied fields
in favor of using the fields in encoder_control_t.cfg directly.

Arttu Ylä-Outinen e78a8dfcf5 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.

Arttu Ylä-Outinen 71633889ce Enable CU QP delta when using rate control
When rate control is enabled, enable cu_qp_delta_enabled_flag in PPS
with diff_cu_qp_delta_depth set to 0. Also adds code for writing the QP
deltas and a new cabac context.

Ari Koivula 4ec039004b 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.

Arttu Ylä-Outinen 2a946bd88e 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.

Arttu Ylä-Outinen aabf6ca3ee Extract encoding code from encoderstate.c
Moves functions kvz_encode_coding_tree and kvz_encode_coeff_nxn from
encoderstate.c to encode_coding_tree.c.
