avformat/hls: reduce default max reload to 3
The 1000 did result in the appearance of a never ending reload loop

The RFC mandates that "If the client reloads a Playlist file and finds that it has not
changed, then it MUST wait for a period of one-half the target
duration before retrying." and if it has changed
"the client MUST wait for at least the target duration before attempting to reload the
Playlist file again"

Trying to reload 3 times seems a better default than 1000 given these
durations

avcodec/jpeg2000dec: jpeg2000 has its own lowres option
jpeg2000 overrides the global lowres variable with a lowres field called reduction_factor
ffmpeg -lowres X causes the reduction_factor to be set
ffplay -lowres X causes both lowres and the reduction_factor to be set
ossfuss sets only lowres

only the ffmpeg variant works. This patch tries to make the other 2 work.

Alternative we could just error out if things are inconsistent.
More complex restructuring should be limited to the master branch
to keep this reasonably easy to backport

avformat/jpegxl_probe: check length instead of blindly reading
Enable the checked bitreader to avoid overread.
Also add a few checks in loops and between blocks so we exit instead of continued
execution.
Alternatively we could add manual checks so that no overread can happen. This would be
slightly faster but a bit more work and a bit more fragile

avcodec/noise_bsf: Check for wrapped frames
Wrapped frames contain pointers so they need specific code to
