avformat/matroskadec: correct spurious keyframe warnings in webm

Minor change to fix for Trac #1003 to avoid squawking about files
with valid keyframes that aren't marked (as opposed to frames that are
marked as keyframes and aren't).

Change correctly surpresses the spurious warnings, while still complaining

avcodec/jpeg2000dec: move "missing SIZ" check up

Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

Merge commit '18a245a2aea31b92bc435f2962a71e060d83b5f7'

* commit '18a245a2aea31b92bc435f2962a71e060d83b5f7':
  jpeg2000dec: Add more checks when parsing headers

The check cannot be true in FFmpeg, but does no harm.
I will move it in a subsequent commit so it can detect missing SIZ

lavd/v4l2: do not fail when VIDIOC_ENUMSTD returns EINVAL without a valid match

With some (buggy) drivers, the VIDIOC_G_STD ioctl returns a std_id that cannot
be matched with any of the enumerated v4l2_standard structures (for example
std_id = 0 or std_id = 0xffffff). Do not fail when we reach the end of the
enumeration without a valid match.

Fixes ticket #2370

Note: This commit message has been modified by Giorgio Vazzana, the original
commit message was:

movenc: Add an option for omitting the tfhd base offset

This makes the output fragments independent of their position in
the output stream, making the output work better when streamed.

QuickTime Player doesn't support fragmented mp4 without the base
data offset, though.

movenc: Write the moof atom in two passes

This is a bit more work, but avoids having to fill in
the data offset field afterwards instead of directly when
the rest of the trun atom is written.

This simplifies future cases where this field needs to be set to
something different.

twinvqdec: Check the ibps parameter separately

This is required, since invalid parameters actually could

rtmp: Support reading interleaved chunks.

A given packet won't always come in contiguously; sometimes
they may be broken up on chunk boundaries by packets of another
channel.

This support primarily involves tracking information about the
data that's been read, so the reader can pick up where it left
off for a given channel.

As a side effect, we no longer over-report the bytes read if
(toread = MIN(size, chunk_size)) == size

certain cases the calculation could overflow leaving the
