apedec: prevent out of array writes in decode_array_0000
...
s->decoded_buffer is allocated with a min_size of:
2 * FFALIGN(blockstodecode, 8) * sizeof(*s->decoded_buffer)
Then it is assigned to s->decoded[0] (and s->decoded_buffer + FFALIGN(blockstodecode, 8)
to s->decoded[1]) and passed as out buffer to decode_array_0000.
In this function 64 elements of the out buffer are written
unconditionally and outside the array if blockstodecode is too small.
This causes memory corruption, leading to segmentation faults or other
crashes.
Thus change decode_array_0000 to write at most blockstodecode elements
of the out buffer.

Otherwise range_start_decoding is not necessarily run and thus
ctx->rc.range still 0 in range_dec_normalize leading to an infinite

GCC tool had a bug of PPC intrinsic interpret, which has been fixed in GCC 4.9.1. This bug lead to
errors in two of our previous patches. We found this when we update our GCC tools to 4.9.1 and by
reading the related info on GCC website. We fix our previous error in two separate commits

avcodec: optimize mathops for Loongson-3 v1
...
HAVE_LOONGSON is replaced by HAVE_LOONGSON3. Even Loongson-2E and 2F support
Loongson SIMD instructs but have low performance for decoding. We plan to focus
on optimizing Loongson-3A1000, 3B1500 and 3A1500, and modify the configure file
to support Loongson-2 series later by adding HAVE_LOONGSON2.
