  FATE: add a test for H.264 with two fields per packet
  h264: fix decoding multiple fields per packet with slice threads

This merge includes two commits because the FATE test was useful in
order to make proper testing.

The merge gets rid of the now unused:
- SLICE_SINGLETHREAD and SLICE_SKIPED macros
- max_contexts
- "again" label in decode_nal_units()

This commit also includes the fix from d3e4d406.

Thanks to wm4 and Michael Niedermayer for their testing.

This treats the case of no slices like no frames which it basically is.

The field is added to the context as other nal related fields are also there
and passing the has_slices field per *arguments is ugly and not consistent

CUVID on GeForce GT 730 and GeForce GTX 1060 does not report any error when
decoding 8K h264 packets. However, it does return an error during
cuvidCreateDecoder call if the indicated video resolution is not
supported.

Given that stream resolution is typically known as a result of probing
it is better to use this information during avcodec_open2 call to fail
immediately, rather than proceeding to decode and never receiving any
frames from the decoder nor receiving any indication of decode failure.

Copied and modified from hwcontext_qsv.c.

This happens because segment_end() returns an error, so seg_write_packet
never proceeds to segment_start(), and seg->avf->pb is never re-set,
so we crash with a null pb when av_write_trailer flushes the packet
queue.

This doesn't seem to be clearly recoverable, so I'm just failing more
gracefully.

Repro:
ffmpeg -i input.ts -f segment -c copy -segment_list /noaxx.m3u8 test-%05d.ts

(assuming you don't have write access to /)

This makes the code 7 times faster with the testcase from libfuzzer
and should reduce the amount of timeouts we hit in automated fuzzing.
(for example 438/fuzz-2-ffmpeg_VIDEO_AV_CODEC_ID_RV40_fuzzer)

The code is also faster with more realistic input though the difference
is small here as that is far from the worst cases the fuzzers pick out
