aacdec: restore arm32 dequantization optimizations 
Unintentionally removed as part of 03cf101645.
Untested, but its assumed that unlike most of the old ARM code,
this one was still working.

b8af0809fb libavcodec/mpegvideo_enc: fix multi-threaded motion estimation rounding for mpeg4 
ff_init_me() was being called after ff_update_duplicate_context(),
which caused the propagation of the initialization to other thread
contexts to be delayed by one frame.

In the case of mpeg4 (or flipflop_rounding), this would make the
hpel_put functions differ between the first thread (which would be
correctly initialized) and the other threads (which would be stale
from the previous frame).

713c6eba8d libavcodec/motion_est: fix penalty_factor for b frames 
In direct_search() and ff_estimate_b_frame_motion(), penalty_factor
would be used before being initialized in estimate_motion_b(). Also,
the initialization would happen more than once unnecessarily.

6fa967810d tests/checkasm/svq1enc: Use proper range for input 
ssd_int8_vs_int16 is only called from encode_block()
in svq1enc.c; it calls it in stages: At stage 0,
the int16_t array contains the difference of two
uint16_t. At each of the following stages, the
int16_t array is filled by subtracting an int8_t from
the current stage's int16_t array. The maximum stage
is five, so the int16_t are in the range
(-255 - 5 * 127)..(255 + 5 * 128).

This commit modifies the checkasm test to only use
values from this range, fixing (undefined) integer overflow
in the test.
