These loops can take a lot of time if count is very large.

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.

Personally, I need the decoder to back out if get_format() returns no
usable pixel format. This didn't work because the error code was not
propagated down the call chain. This in turn happened because the
variable declaration removed in this patch shadowed the variable, whose
value is returned at the end of the function. Consequently, failures of
decode_nal_unit() were ignored in this place.

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().

This significantly reduces the amount of stack space needed and
also permits to simply copy the rice context again without speed

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.
