Arttu Ylä-Outinen 631ef53d2a Fix inter cost calculations
Inter costs are computed using SAD except when fractional motion
estimation or bi-prediction is enabled. This commit changes
search_pu_inter_ref to recalculate the cost with SATD. Fixes inter/intra
cost comparisons since intra costs are always SATD costs.

Arttu Ylä-Outinen 1efa2708b2 Do SAO reconstruction for a single CTU at a time
Moves SAO reconstruction into encoder_state_worker_encode_lcu instead of
doing it in a separate step for the whole CTU row. Reconstruction of the
rightmost 10 pixels and bottommost 10 pixels of a CTU is delayed until
the neighboring CTU has been deblocked.

Doing SAO for the whole CTU row at a time caused unnecessary inter-CTU
dependencies when using WPP and OWF. The first CTU of a row would need
to wait until SAO was done for the row below in the previous frame.
Moving SAO reconstruction to immediately after deblocking each CTU fixes
this problem.

Ari Koivula 61fc3e87ba Run include-what-you-use fix_includes.py fix_includes.py
The includes should make more sense now and not just happen to compile
due to headers included from other headers.

Used a modified version of IWYU. Modifications were to attribute int8_t
and so on to stdint.h instead of sys/types.h and immintrin.h instead of
more specific headers.

include-what-you-use 0.7 (git:b70df35)
based on clang version 3.9.0 (trunk 264728)

Ari Koivula 8ad7d2a714 Move interlacing stuff to libkvazaaar API
This moves the interlacing from CLI code to api->encoder_encode, in
order to make it possible to use field coding through the lib API.

The field order is now determined per frame, as FFmpeg gives it per
frame and it's signaled per frame.

As a side effect, the CLI also now prints info from frames instead of
fields. While we might want to extend the API in the future to allow
printing of more detailed information about fields, for now it's
more important that the CLI uses the real lib API.

PSNR calculation for interlaced frames disabled until we have a way to
avoid deinterlacing the frame when it's not necessary.

Ari Koivula 947bae24f9 Update Doxygen documentation
Add module information to all header files.

Update all header file documentations to briefly say what they are, and
to use the javadoc format so the brief actually gets included into the
doxygen documentation.

Remove \file from implementation files, in order to not repeat the info
from the header files.

Add files under strategies and tools to Doxygen and update the Doxygen
settings to be just plain better.

Make README be the main page of Doxygen documentation.

Ari Koivula c94707e6e8 Fix bug with OWF+FME+deblocking
Increases the MV safety margin of OWF from 2 to 3 when deblocking
is used and 4 when both deblocking and FME are used.

Fractional pixel motion estimation can move the vector one more pixel
down causing checksum error. This fixes that error by increasing the
OWF safety margin and changes the interface, so that different margin
can be used when FME or deblocking are not in use.

frames. The timestamps are copied to the reconstructed frames.

Ari Koivula d7383ccb25 Change license to LGPL.
- Everyone who has contributed code to the project has been asked to license
  their contributions under LPGL and they have agreed.

- COPYING file changed to say LGPLv2.1 instead of GPLv2.

- GPL changed to LGPL in the header of every single file that a header and
  header added to the few that were missing one.

- Also.. Happy new year!
