34b9c7612d sonic: make sure num_taps * channels is not larger than frame_size
If that is the case, the loop setting predictor_state in
sonic_decode_frame causes out of bounds reads of int_samples, which has
only frame_size number of elements.

ea4b99f82c opus_silk: fix typo causing overflow in silk_stabilize_lsf
Due to this typo max_center can be too large, causing nlsf to be set to
too large values, which in turn can cause nlsf[i - 1] + min_delta[i] to
overflow to a negative value, which is not allowed for nlsf and can
cause an out of bounds read in silk_lsf2lpc.

8b30abd020 ffm: reject invalid codec_id and codec_type
A negative codec_id cannot be handled by the found_decoder API of
AVStream->info: if the codec_id is not recognized, found_decoder is set
to -codec_id, which has to be '<0' according to the API documentation.

This can cause NULL pointer dereferencing in try_decode_frame.

Also make sure the codec_type matches the expected one for codec_id.

435b0ab969 golomb: always check for invalid UE golomb codes in get_ue_golomb
Also correct the check to reject log < 7, because UPDATE_CACHE only
guarantees 25 meaningful bits.

This fixes undefined behavior:
runtime error: shift exponent is negative

Testing with START/STOP timers in get_ue_golomb, one for the first
branch (A) and one for the second (B), shows that there is practically no
slowdown, e.g. for the cavs decoder:

With the check in the B branch:
    629 decicycles in get_ue_golomb B, 4194260 runs,     44 skips
    433 decicycles in get_ue_golomb A,268434102 runs,   1354 skips

Without the check:
    624 decicycles in get_ue_golomb B, 4194273 runs,     31 skips
    433 decicycles in get_ue_golomb A,268434203 runs,   1253 skips

Since the B branch is executed far less often than the A branch, this
change is negligible, even more so for the h264 decoder, where the ratio
B/A is a lot smaller.

88ccca204a avutil/mathematics: Do not treat INT64_MIN as positive in av_rescale_rnd
