  libopencore-amr: Fix ff_dlog()/av_log() invocations

The log changed in our tree in 4a289624
is kept as is since it's the correct thing to do (the log mentions what
the first byte *was*, so it's refering to the source packet, not the
encoded bitstream).

  mpegts: Validate the SL Packet Header Configuration

See e630ca51

Our local timestamp_len > 64 is adjusted to > 63 to match the Libav
check and the actual specifications (14496-1, 10.2.2).

There is no need to request a sample as it violates the specifications
and such a file would likely be the result of a crafted/fuzzed sample.

On the other hand, the clipping of the value is kept for extra safety.
