73447eb4bd Use correct scaling table for bwd-pred MVs in second B-field 
When scaling backward predicted MVs in second B-field, the scaling table is
opposite of that for P field pictures; i.e. first field P table will be used as
second field B table and second field P table will be used as first field B
table. This is not documented in the spec, but exists in the ref. decoder.

This fixes SA10139.

cd14e297e6 prores: do not set pixel format on codec init

d341d5fd2c dnxhdenc: fixed signed multiplication overflow 
The low 32 bits of a multiplication are the same for signed

is thus equivalent while avoiding signed overflow, which is

641c7afe3c AVOptions: add new API for enumerating children. 
This will allow the caller to enumerate child contexts in a generic way
and since the API is recursive, it also allows for deeper nesting (e.g.
AVFormatContext->AVIOContext->URLContext)

This will also allow the new setting/reading API to transparently apply
to children contexts.

adds a get_ue_golomb_long() function supporting up to 31
leading zeros, which is the maximum for these syntax

be1242a3f2 h264: fix detection of optional trailing PPS elements 
The PPS may contain a few trailing elements whose presence is
only signalled by data remaining after the the mandatory part
has been parsed.  The current code fails to take into account
the rbsp_trailing_bits() when deciding whether to parse these
optional elements.  Assuming no unnecessary padding bytes are
passed to this function, the optional elements are present if
either more than 8 extra bits remain or the remaining bits do
not form a valid rbsp_trailing_bits() after the mandatory PPS
elements have been parsed.

bb59156606 vp8: fix signed overflows 
In addition to avoiding undefined behaviour, an unsigned type
makes more sense for packing multiple 8-bit values.

ac6eab1496 put_bits: fix invalid shift by 32 in flush_put_bits() 
If flush_put_bits() is called when the 32-bit buffer is empty,
e.g. after writing a multiple of 32 bits, and invalid shift by
32 is performed.  Since flush_put_bits() is called infrequently,
this additional check should have negligible performance impact.

14c21c1ff5 H264: Only wait before triggering ff_thread_setup_complete() until the next slice that contains a start-of-field/frame macroblock 
This allows concurrent decoding of the last field/frame, rather than
only the last slice, of data packets with multiple NAL units packed
together.

This will fix the slowdown reported in e.g. bug 52.
