Remove Exp-Golomb lookup table

Add a fast lane for byte-aligned bitstream writes
...
The CABAC engine only writes to the bitstream when it has a full byte.
These writes are also always byte-aligned, so there is no need to even
check for stream alignment.
Speedup was around 3% with ultrafast and low QP.

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)

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.

Add new kvz_bitstream_align which only aligns when needed.
...
- Changing picture_timing_sei_message to align doesn't change anything, but
protects against future changes if more data is added there in future.

Rename kvz_bitstream_align to kvz_bitstream_rbsp_trailing_bits.
...
- The syntax is called rbsp_trailing_bits in spec and 1 byte is added
even when the bitstream is already aligned, so align is a bad name.

Write slice header before joining child streams.
...
The lengths of the leaf streams must be available when the slice header
is written. Writing the header before joining child streams removes the
need to copy leaf bitstreams instead of moving them.

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!
