It's a hack which was created to allow for multiple options with
different defaults to refer to same field (e.g. 'b' vs 'ab'). There is
no need for it anymore.
Specifically, trellis, nr, me_range, me_method, subq, b_strategy,
keyint_min, chroma_me and coder.
Change their defaults to -1 and apply them after
x264_param_default_preset() if the user explicitly set them.
Specifically: gop_size, max_b_frames, scenechange_threshold, qmin, qmax,
max_qdiff, qblur, qcompress and refs.
Change their default values to -1 and only use them if the user
explicitly set them. Otherwise x264 defaults are used.
Move setting those options after x264_param_default_preset(), so they
don't get overwritten by it.
This is done in order to clarify the non-video-specific nature of the
buffersink code, as the result of the video/audio API unification of
the previous commit, and for improving overall consistency.
The new API is more generic (no distinction between audio/video for
pulling frames), and avoids code duplication.
A backward compatibility layer is kept for avoiding tools ABI breaks
(only for the video binary interface, audio interface was never used
in the tools).
* qatar/master:
ac3enc: Add channel coupling support for the fixed-point AC-3 encoder.
ac3enc: scale floating-point coupling channel coefficients in scale_coefficients() rather than in apply_channel_coupling()
ac3enc: fix encoding of stereo ac3 files when rematrixing is disabled.
wavpack: fix wrong return value in wavpack_decode_block()
avconv: fix parsing metadata specifiers.
fate: use +frame+slice named constants instead of '3'
mpeg12: propagate more real return values through chunk decode error return and fix some indentation
wavpack: use context reset in appropriate places
avconv: move mux_preload and mux_max_delay to options context
avconv: move bitstream filters to options context.
avconv: move rate_emu to options context.
avconv: move max_frames to options context.
avconv: move metadata to options context.
avconv: move ts scale to options context.
avconv: move chapter maps to options context.
avconv: move metadata maps to options context.

swscale: error dithering for 16/9/10-bit to 8-bit.
Based on a somewhat similar idea in FFmpeg's swscale copy.

swscale: rename uv_off/uv_off2 to uv_off_px/byte.
This function should return number of samples decoded, not number of bytes
decoded.
