Using the old code, half of it was unused and the other half was too
small for e.g. >8bpp interlaced data, causing random buffer overruns.

It was wrong in colorspaces where horizontal and vertical chroma
subsampling are not the same, e.g. 422.

This is needed by the new AVOptions API.

'while', 'if/else', and 'switch' statements.

also fixes some spacing, but only if already changing a line

Read the key in the first, value in the second.

This allows to avoid pointless strdups and simplify decode_str() by
dropping two of its parameters.

While they're technically invalid, it's better to skip them and try to
read the rest of the tag.

VPX_ERROR_RESILIENT_DEFAULT and VPX_ERROR_RESILIENT_PARTITIONS weren't
defined before 4cb0ebe5b27d35ccc2a78c1d16f2622ddef21f74 (CommitDate: Tue

The inline asm added in bf5d46d8 uses the 'y' modifier which
is only supported from gcc 4.5.  This check allows building
with older compilers.

If no threading is requested do not issue warning about unsupported
threading algorithm.

Specifically, qmin/qmax, gop_size and keyint_min.

Uses 'buf' directly instead of a separate iterator variable 'in'.
