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

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.

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.

This is required, since invalid parameters actually could

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

Since the number of channels is multiplied by 36 and assigned to
to a uint16_t, make sure this calculation didn't overflow. (In
certain cases the calculation could overflow leaving the
truncated block_align at 0, leading to divisions by zero later.)

A change in framesize caused a perpetual loss of synchronization.
So read (and use) the frame size from the frame header instead of
