Add CODEC_FLAG2_SKIP_MANUAL (exposed as "skip_manual"), which makes
the decoder export sample skip information via side data, instead
of applying it automatically. The format of the side data is the
same as AV_PKT_DATA_SKIP_SAMPLES, but since AVPacket and AVFrame
side data constants overlap, AV_FRAME_DATA_SKIP_SAMPLES needs to
be introduced.
This is useful for applications which want to do the timestamp
calculations manually, or which actually want to retrieve the
padding.

Unfortunately this was not explicitly documented and thus
might be risky.
But all uses I could find in FFmpeg and one in VLC had a memleak
in these cases, and I could not find any that relied on the previous
behaviour.

The reasoning behind this addition is that various third party
applications are interested in getting some motion information out of a
video "for free" when it is available.
It was considered to export other information as well (such as the intra
information about the block, or the quantization) but the structure
might have ended up into a half full-generic, half full of codec
specific cruft. If more information is necessary, it should either be
added in the "flags" field of the AVMotionVector structure, or in
another side-data.
This commit also includes an example exporting them in a CSV stream.

This allows getting rid of the many, slightly differing, implementations
of basically the same thing.

In order to support metadata being set as an option, it's necessary to be able
to set dictionaries as values.
Signed-off-by: Anton Khirnov <anton@khirnov.net>
The only flags, for now, indicate if metadata was updated and are set after each call to
av_read_frame(). This comes with the caveat that, on stream start, it might not be set properly
as packets might be buffered in AVFormatContext.packet_buffer before being given to the user
in av_read_frame().

It allows attaching other external, opaque data to the frame and passing it
through the reordering process, for cases when the caller wants other data
than just the plain packet pts. There is no way to cleanly achieve this
without the field.
The rationale is that you have a packed format in form
<greyscale sample> <alpha sample> <greyscale sample> <alpha sample>
and shortening greyscale to 'G' might make one thing about Greenscale instead.
An alias pixel format and color space name are provided for compatibility.
