a7b86878fb audio: Move audioaggregator base class to a library
It's useful enough already to be used in other elements for audio aggregation,
let's give people the opportunity to use it and give it some API testing.

1eef58c3ce audioaggregator: Split base class from audiomixer
Also:
-  Don't modify size on early buffer
   The size is the size of the buffer, not of remaining part.
- Use the input caps when manipulating the input buffer
   Also store in in the sink pad
- Reply to the position query in bytes too
- Put GAP flag on output if all inputs are GAP data
- Only try to clip buffer if the incoming segment is in time or samples
- Use incoming segment with incoming timestamp
   Handle non-time segments and NONE timestamps
- Don't reset the position when pushing out new caps
- Make a number of member variables private
- Correctly handle case where no pad has a buffer
  If none of the pads have buffers that can be handled, don't claim to be EOS.
- Ensure proper locking
- Only support time segments

8227310d22 audiomixer: Mark a discont when we receive a new segment event
This allows us to handle new segment events correctly; either by dropping
buffers or inserting silence; for example if the offset is changed on an srcpad
connected to audiomixer.

8465c0915e audiomixer: Change blocksize property to output-buffer-duration in time format
This makes the interface of audiomixer independent of the actual caps.

bf3896b2bd audiomixer: Track discont-time per pad instead of globally
We do discont handling per pad, not per element!

c158e019c1 audiomixer: Set the sinkpad segments basetime after seeking
Otherwise stream offset and running time comparison will not be
correct, leading to segfaults after seeks
