bug 1198656 delay AudioBuffer allocation until required r=padenot This saves an allocation and zeroing for buffers generated by AudioNodes and avoids allocation altogether for empty buffers. Incidentally, RestoreJSChannelData() now avoids unnecessary recreation of Float32Arrays if they already exist after a previous call failed.
