henrik.lundin@webrtc.org 3154a1cf9d Reland r8210 "Add a new parameter to ACMGenericCodec constructor""
This effectively reverts r8211.

The problem with r8210 was that the change in constructor signature was not done for other codec selections that then default one. That is, some code that was hidden under #ifdef did not get updated. This is now fixed.
