lavd/xcbgrab: do not try to create refcounted packets.

The framework will allocate a buffer and copy the data to it,
that takes time. But it avoids constently creating and
destroyng the shared memory segment, and that saves more time.

On my setup,
from ~200 to ~300 FPS at full screen (1920×1200),
from ~1400 to ~3300 at smaller size (640×480),
similar to legacy x11grab and confirmed by others.

Plus, shared memory segments are a scarce resource,
allocating potentially many is a bad idea.

Note: if the application were to drop all references to the
buffer before the next call to av_read_frame(), then passing
the shared memory segment as a refcounted buffer would be
even more efficient, but it is hard to guarantee, and it does
not happen with the ffmpeg command-line tool. Using a small
number of preallocated buffers and resorting to a copy when
the pool is exhausted would be a solution to get the better
of both worlds.

lavf/mov.c: Use the first sidx for tracks without sidx.

According to spec ISO_IEC_15444_12 "For any media stream for which no segment index is present, referred to as non‐indexed stream, the media stream associated with the first Segment Index box in the segment serves as a reference stream in a sense that it also describes the subsegments for any non‐indexed media stream."

crystalhd: Update high level description

We don't need to document the horrible hacks that we removed.

crystalhd: Simplify output frame handling

The old code had to retain a partial frame across two calls in
the case of separate interlaced fields. Now, we know that we'll
get both fields within the same receive_frame call, and so we
don't need to manage the frame as private state any more.

crystalhd: Loop for a frame internally where possible.

It's not possible to return EAGAIN when we've passed input EOF and are
in draining mode. If do return EAGAIN, we're saying there's no way to
get any more output - which isn't true in many cases.

So let's handled these cases in an internal loop as best we can.

crystalhd: Keep NOPTS_VALUE so we know it's not there.

crystalhd: Remove h.264 parser

Now that we don't need to do ridiculous things to work out if a
frame is interlaced or not, we don't need an extra h.264 parser.
