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).

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.
