9806b9ab5c Revert "Don't use expressions with side effects in macro parameters" 
This reverts commit 25bacd0a0c32ae682e6f411b1ac9020aeaabca72.

Since 230b1c070, the bytewise AV_W*() macros only expand their
argument once, so revert to the more readable version of these.

25bacd0a0c Don't use expressions with side effects in macro parameters 
AV_WB32 can be implemented as a macro that expands its parameters
multiple times (in case AV_HAVE_FAST_UNALIGNED isn't set and the
compiler doesn't support GCC attributes); make sure not to read
multiple times from the source in this case.

a115eb9e75 mimic: do not release the newly obsolete reference at the end of decoding 
The reference frames are used in update_thread_context(), so modifying
them after finish_setup() is a race. The frame in question will be
released during the next decode call.

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().
