H264: Only wait before triggering ff_thread_setup_complete() until the next slice that contains a start-of-field/frame macroblock

This allows concurrent decoding of the last field/frame, rather than
only the last slice, of data packets with multiple NAL units packed
together.

This will fix the slowdown reported in e.g. bug 52.

It prevents leaving the state only half initialized.

Some of the arguments given to init_vlc() come from the stream
and can be corrupted.

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.
