* commit '38efff92f1ef81f3de20ff0460ec7b70c253d714':
  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 d3e4d406b.

Thanks to wm4 and Michael Niedermayer for their testing.

  h264: eliminate decode_postinit()

Also includes fixes from 1f7b4f9abc and e344e65109.

Original patch replace H264Context.next_output_pic (H264Picture *) by
H264Context.output_frame (AVFrame *). This change is discarded as it
is incompatible with the frame reconstruction and motion vectors
display code which needs the extra information from the H264Picture.

4a9bab3db0 h264: fix decoding multiple fields per packet with slice threads
Since we only know whether a NAL unit corresponds to a new field after
parsing the slice header, this requires reorganizing the calls to slice
parsing, per-slice/field/frame init and actual decoding.

In the previous code, the function for slice header decoding also
immediately started a new field/frame as necessary, so any slices
already queued for decoding would no longer be decodable.

After this patch, we first parse the slice header, and if we determine
that a new field needs to be started we decode all the queued slices.

f450cc7bc5 h264: eliminate decode_postinit()
This function's purpose is not very well defined. Currently it does two
(only marginally related) things: selecting the next output frame and
calling ff_thread_finish_setup() for frame threading. The first of those
more properly belongs under field_start(), while the second can be
called directly from decode_nal_units().

a8cbe5a0cc h264_ps: export actual height in MBs as SPS.mb_height
Currently, SPS.mb_height is actually what the spec calls
PicHeightInMapUnits, which is half the frame height when interlacing is
allowed. Calling this 'mb_height' is quite confusing, and there are at
least two associated bugs where this field is treated as the actual
frame height - in the h264 parser and in the code computing maximum
reordering buffer size for a given level.

Fix those issues (and avoid possible future ones) by exporting the real
frame height in this field.

  h264: factor out setting the parameter sets for a frame

Michael's changes on top of the merge undo parts of the original diff
that are not factorization:

"The call point is left where it was before. Such a change should be in
a separate commit and has multiple issues, one being null pointer
dereferences the other is that some safety checks would become
conditional.

I tried to split the PPS init between the new and old functions
similarly to the SPS code."
