Clobbering these tables will temporarily clobber the template used
as a basis for other threads to start decoding from. If the other
decoding thread updates from the template right at that moment,
subsequent threads will get invalid (or, usually, none at all) mmco
tables. This leads to invalid reference lists and subsequent decode
failures.
Therefore, instead, decode the mmco tables only for the first slice in
a field or frame. For other slices, decode the bits and ensure they
are identical to the mmco tables in the first slice, but don't ever
clobber the context state. This prevents other threads from using a
clobbered/invalid template as starting point for decoding, and thus
fixes decoding in these cases.
This fixes occasional (~1%) failures of h264-conformance-mr1_bt_a with
frame-multithreading enabled.

Since resolution change support this also was exploitable, which is
how it was found.
Fixes read after free and out of array reads.

This could also be fixed by changing the argument type if
someone prefers that and wants to change it ...

This makes the behaviour defined when they wrap around. The value
assigned to expected_prior was a uint32_t already.

Without this, we'd signal a huge loss rate (due to unsigned
wraparound) if we had received one packet more than expected (that
is, one seq number sent twice). The code has a check for lost_interval
<= 0, but that doesn't do what was intended as long as the variable is
unsigned.

The code below the comment does not at all relate to statistics,
and even if moved to the right place, the comment adds little
value.

Fixes null pointer dereference later, since if this function failed,
a positive return value was returned to the caller.
