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

It has no advantage and seems to cause compile issues with
some combinations of compiler/compiler flags/PIC.

This commit is plain wrong, theres no reason to error out at this point nor is the
error value guranteed to be negative as it should be
This reverts commit 289c60001f.
Replace:
s->last_picture_ptr->f.key_frame = 0;
with:
s->last_picture_ptr->key_frame = 0;
This is required since mpegvideo.h:Picture now contains an embedded
AVFrame f, rather than a literal copy of the AVFrame fields.
We use this flag to tell when to assume decoded data is free
from artifacts after a seek. The mpeg1/2 decoder will generate
a dummy frame if decoding is started on a non keyframe. This
will sadly be output from decoder to player and displayed
as a gray screen.

User-provided data should never trigger an assert; return error instead.
Also fix an instance of get_bits where get_bits_long should have been used.
This eliminates the following warning:
