This reduces the call overhead slightly. More noticeably, it
restores the earlier (unintended?) feature that condition variable
functions work just fine even if w32thread_init() hasn't been called.
This was broken as a side effect of 4622f11f, if explicitly targeting
Vista+.

This makes w32threading work in VP8 again, if targeting Vista+.

If a client tries to read the file while it's being updated, the client
would get an incomplete manifest. Instead write to a separate temp file
and atomically rename it to replace the previous one.

The parsing function return AVERROR and AAC_AC3_PARSE_ERROR values,
make sure they are not misunderstood.

The element was only being written when the value == 1.  But the default
value of this element is 1, so this has no useful effect.  This element
needs to be written when the value == 0.

On failures in the write_trailer function, we could also ignore
the errors and try to finish the file despite these errors (which
would only leave an incomplete chapters track). It's probably better
to signal the error clearly to the caller though (and if this
function failed there's no guarantee that there's enough memory to
finish the trailer either).

This both allows factoring out size check for both MetaSound and TwinVQ-VQF
decoders and fixes the situation when there are several MetaSound frames
stuffed together (that happens in 8kHz @ 8kbps MetaSound in ASF for example).

This ensures that decode_cabac_residual_internal actually does get inlined,
which it otherwise does not, even though it is marked as always_inline.

The functions are used by all codecs that enable the h264chroma component
and the file is already compiled conditional on h264chroma being enabled.

Most of our VP56 optimizations are VP6-only and will stay that way.
So avoid compiling them for VP5-only builds.

QuickTime will play multiple audio tracks concurrently if this flag is
set for multiple audio tracks.  And if no subtitle track has this flag
set, QuickTime will show no subtitles in the subtitle menu.

Faststart moves the moov atom to the beginning of the file and rewrites
the rest of the file after muxing is complete.
