G729_BITEXACT is never set, so the code is all dead code.

Mpegvideo would free frames as soon as they're not the next or prev
picture. This is fine for a single-threading model, but fails miserably
in a system where pictures can be referenced (as e.g. last/prev pic)
in other threads. Keeping track of ownership of pictures keeps image
references (e.g. motion vectors, or the reference of a motion vector)
alive as long as the picture data itself is alive.

This also happens to fix make THREADS=[3-16] fate-vsynth[12]-error.

Use of these has been broken ever since the h264 idct was changed
to always use transposed inputs.  Furthermore, they were only
ever used if some *other* non-default idct was requested.

This checks if the set of selected exponent strategies for all blocks in a
channel are in the frame exponent strategy table, and if so, writes the
table index instead of each strategy. This saves up to 7 bits per channel per
frame, so the overall effect on quality is small.

be used in the E-AC-3 encoder.

The change to LOCAL_ALIGNED means the declared object must be an
array and the subsequent test should not use the & operator.

Rename it to "avctx", the old name was confusing as the function is
used also with decoder contexts.

It's more readable and less prone to breakage.
