With this change, the currently used encoder is held in a scoped_ptr. iSAC is a special case, since the encoder instance is also a decoder instance, so it may have to be available also if another send codec is used. This is accomplished by having a separate scoped_ptr for iSAC. Remove mirror ID from ACM codec database functions, and remove unused functions from the database.
