Summary: Peek size of internal buffer

Initial Comment:
Most of the time I use mpg123_decode() with fixed size pre-allocated input and output buffer
Without a peek function to let me know how much buffer can be decoded without feeding new data,
I will run into situations either:
- Feed data faster than consumption --> mpg123 internal buffer get increase without bound, or
- Peridoically invoke mpg123_read() --> having many tiny output buffer size, which will do no good (memory/performance) to my underlaying audio engine

So I would suggest to have a function like int mpg123_peek_outbuffer();
May be there is some existing API that I can use to solve my problem I missed?
