Fix bipred and temporal MVP
...
- Fixes two errors in calculating the POC for the reference frame for
temporal candidate MV scaling.
- Fixes using the MV for the wrong direction when the temporal MV
predictor block uses bi-prediction.
Fixes #160 .

Drop field inter.mvd from cu_info_t
...
Instead of storing the mv differences in cu_info_t, they are computed
from the mv candidates and the motion vector. Reduces the size of
cu_info_t.

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.

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.

Implement inter recon for non-square blocks.

Adds parameter height to functions kvz_inter_recon_lcu and
kvz_inter_recon_lcu_bipred and makes them work on non-square sizes.

Rename parameter encoder_state to state in all functions.

- It's so widely used that there isn't really need to emphasize that
it's the encoders state. Also, it isn't really the encoders state,
but encoding jobs state.

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

- 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!
