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.

support writing encrypted mp4 using aes-ctr, conforming to ISO/IEC
23001-7.
3 new parameters were added:
- encryption_scheme - allowed values are none (default) and cenc-aes-ctr
- encryption_key - 128 bit encryption key (hex)
- encryption_kid - 128 bit encryption key identifier (hex)

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.
