323b132f5e Protect ACM decoder buffer in stereo.
In https://code.google.com/p/webrtc/source/detail?r=8730, I did a protection on ACM decoder buffer from being overflow.

However, the I misunderstood the return unit for PacketDuration(), and therefore, stereo decoders are not well protected.

This CL fixed this.

6dba1ebd14 Make AudioDecoder stateless
The channels_ member varable is removed from the base class, and the
associated accessor function is changed to Channels() which is a pure
virtual function.

7f7d7e3427 Prevent crash in NetEQ when decoder overflow.
NetEQ can crash when decoder gives too many output samples than it can handle. A practical case this happens is when multiple opus packets are combined.

The best solution is to pass the max size to the ACM decode function and let it return a failure if the max size if too small.

1eda4e3db6 Reland r8476 "Set decoder output frequency in AudioDecoder::Decode call"
This should be safe to land now that issue 4143 was resolved (in r8492).
This change effectively reverts 8488.

Original commit message:
This CL changes the way the decoder sample rate is set and updated. In
practice, it only concerns the iSAC (float) codec.

One single iSAC decoder instance is used for both wideband and
super-wideband decoding, and the instance must be told to switch
output frequency if the payload type changes. This used to be done
through a call to UpdateDecoderSampleRate, but is now instead done in
the Decode call as an extra parameter.

903182bd8e Revert r8476 "Set decoder output frequency in AudioDecoder::Decode call"
This change uncovered issue 4143, evading the Memcheck suppression
since the signature is changed in the Decode function.

A fix for this is in the making; see
https://review.webrtc.org/36309004. This CL will be re-landed once the
fix is in place.

It belongs with the codecs, next to the AudioEncoder interface.

Apparently, it caused all sorts of problems I don't have time to
straighten out right now.
