nut->last_syncpoint_pos doesn't necessarily change between resync
attempts, so find_any_startcode can return the same startcode again.

Thus remember where the last resync happened and don't try to resync
before that.

This can't be done locally in nut_read_packet, because this wouldn't
prevent infinite resync loops, where after the resync a packet is
returned and while reading a following packet the resync happens again.

af_ashowinfo, due to the enum AVAudioServiceType use.

Some clients incorrectly set 24 as bits_per_coded_sample, while
the actual value is preserved in one of the codec headers.
In order to work around this, delay the check until decode_frame().

Without this change, if you link with an 8bit libx265 and try to specify
a 10bit input color space via:

  ffmpeg -i in.mov -c:v libx265 -pix_fmt yuv420p10le out.mp4

It will error with:

  Incompatible pixel format 'yuv420p10le' for codec 'libx265',
  auto-selecting format 'yuv420p'

With this fix, it will learn if a 10bit libx265 is available at startup,
and thus allow 10bit input color spaces.
