Make the macro return the appropriate pointer type, and make sure the
free function takes an argument of the same type. This also eliminates
some boilerplate type-casting code.

Some gcc targets report ifunc as a supported attribute, while at the
same time actually trying to build the object fails with "ifunc not
supported on this target". Be more prejudicial with ifunc usage.

Track audio writes in the mix buffer to set the `active` flag to true
whenever a write occurs, which makes it possible to create the buffer in
an inactivate state and implicitly set it active on demand.
Handle the mix buffer not returning any data in the RTP sending logic
(which is what happens for an inactive buffer) by simply not sending any
packets.

... as an extra offset for newly added sources, based on the difference
between the last runtime (read time) of the buffer and the current time.

A simple circular audio buffer that allows mixing multiple sources of
audio. Sources are tracked by SSRC and all sources are expected to
provide audio in the same format (same clock rate, channels, sample
format).
Only one consumer per buffer is supported, which is expected to retrieve
buffered audio at regular intervals (ptime) and so continuously empty
the buffer.
The first audio source to write into the buffer at the leading edge of
the circular buffer has its audio simply copied into the buffer, with
the leading edge advanced, while other later sources writing into the
buffer mixed into the existing buffered audio at their respective write
positions.
