Enforce bit depth promised by --input-bitdepth to avoid crashes when
larger values are provided.
Do endianess byte swap for all bytes when the buffer gets extended
to multiple of 8 pixels, and not just the number of input pixels.
Don't swap bytes on a little-endian system.
- Reduce indentation to 6 spaces
- Word wrap everything to under 80 characters
- Remove defaults from options covered by presets
- Add a dash in front of argument descriptions
- Add --(no-) to names of parameters that accept it and remove mention
of enabling or disabling
- Add executable and scripts as a dependancy to make docs
This value is not represented in the HEVC bitstream, which is why it
was not set previously. FFmpeg sets and needs it however, so make the
CLI set it as well to make sure we handle it correctly.
Depending on the distro, the pkg-config package name of crypto++ could
be either cryptopp or libcrypto++. This commit changes configure to
check for both instead of cryptopp only.
The rd-complexity of slow presets is better with a less agressive GOP.
Adding the GOP as part of the preset improved BDRate enough, that it
didn't make sense anymore to have a veryslow target the best BDRate.
Instead, push that responsibility to placebo by making it a little bit
faster.
Now that WPP is on by default, Valgrind is finding memory leaks on
these tests. It's not a priority so I'll just disable it for now.

GOPs with depth 1 had the same structure as those with depth 2:
g4d3t1 = 3 2 3 1
g4d2t1 = 2 2 2 1
g4d1t1 = 2 2 2 1
It now results in the correct:
g4d1t1 = 1 1 1 1
Coding inter without GOP of any kind really isn't a very sensible
default. Defaulting to B-GOP of some kind would be more better,
but lp-gop is more robust for now.
Use the vectorized general SSE41 inter SAD in AVX reg_sad for shapes
for which we don't have AVX versions yet.
Also improves speed of --smp and --amp a lot. Got a 1.25x speedup for:
--preset=ultrafast -q 27 --gop=lp-g4d3r3t1 --me-early-termination=on --rd=1 --pu-depth-inter=1-3 --smp --amp

Add tests for the extreme shapes that can happen when a motion vector
points outside the frame. A single pixel case where it probably doesn't
make sense to call a vectorized function, and the maximum size where it
definitely does make sense to call a vectorized function.
Add implementations for these functions that process the image line by
line instead of using the 16x16 function to process block by block.
The 32x32 is around 30% faster, and 64x64 is around 15% faster,
on Haswell.
