In preparation for multithreaded decoding.

This applies to every library where performance is not critical.

And deprecate av_dlog macro.

The AVSC_API changes in the new headers mean that the 2.6 alphas
are just as incompatible as 2.5 is.
Signed-off-by: Diego Biurrun <diego@biurrun.de>

In order to safely exit when the user tries to use AviSynth 2.5, the
continue_on_fail value for 2.6's functions need to be set to 1.
Otherwise, the library loader fails before the 'upgrade to 2.6'
log message appears.

They seem to sometimes trigger with old AVI files. They are just
confusing, do not help anyone, and use sloppy language.

This is optional, but ensures that linking with -Wl,--as-needed does not
drop the library containing the MMAL VC driver. The driver normally
"registers" itself in the library constructor, but since no symbols are
explicitly referenced, the linker could remove it with --as-needed
enabled.

Although it's not allowed to use only allows 'nclc' in ISOM files, there
are samples that do not always respect this rule. This change prevents
atom overread and a spurious color range initialization.

Generally, libavformat exports cover art pictures as video streams with
1 packet and AV_DISPOSITION_ATTACHED_PIC set. Only matroskadec exported
it as attachment with codec_id set to AV_CODEC_ID_MJPEG.

Obviously, this should be consistent, so change the Matroska demuxer to
export a AV_DISPOSITION_ATTACHED_PIC pseudo video stream.

Matroska muxing is probably incorrect too. I know that it can create
broken files with an audio track and just 1 video frame when e.g.
remuxing mp3 with APIC to mkv. But for now this commit does not change
anything about muxing, and also continues to write attachments with
AV_CODEC_ID_MJPEG should the muxer application have special knowledge
that the Matroska is broken in this way.

And use it in libavformat.

Based on a similar patch by Stefano Sabatini <stefasab@gmail.com>.

The strptime implementation is supposed to support whitespace and %T.

They are no longer initialized in ff_h264_decode_init() since 43fd3dd8,
so svq3 needs to initialize the manually.

Fixes svq3 decoding, broken since 43fd3dd8.

The previous documentation was very vague and almost misleading.

The generic code copies the main context's private data to all the
others. However that is quite dangerous, as it might end up copying some
pointers that are or will become invalid.

Since everything we actually need will be copied later in
update_thread_context(), it's safest to zero the private data in
init_thread_copy(), so it works the same way as init for the main
context.
