8ea355e52c audioringbuffer: Avoid overflows of segment done counter
This counter is incremented once for every segment, meaning it would
e.g. overflow after 24 days when using 1ms segments. Once that happens,
completely wrong positions are reported and invalid memory is handed out
for writing/reading the next segments.

As the affected variables are unfortunately part of the public API of
the struct, a second set of variables is added together with accessor
functions and both variables are kept in sync for backwards
compatibility.

All existing users of the two variables are moved to the new ones but
external code might still run into the overflow.

This also slightly breaks API as external code updating the variables
will have no effect anymore but the only known user of this is
pulsesink.

4790a44d10 Revert "audiobasesink: Don't wait on gap events"
This reverts commit 8e923a8e2d.

This caused regressions, see #3303.

Without this commit, osxaudiosrc ! osxaudiosink won't work
right, but since that hasn't really been a huge problem
for years it's probably best to revert this until a proper
solution can be figured out.

c4789e6de5 audio: Consider the expected timestamp for discont-wait handling
Otherwise if there is a huge gap it will only be considered a
discontinuity after another discont-time amount of buffers has passed.

Like this it will be immediately a discontinuity if the gap between the
expected and received time becomes bigger than the discont-time.

The last part of the test was actually testing for this behaviour and
expected the previous behaviour. Most other tests also had to be
adjusted because discont will now happen at slightly different times
than before.

62f09513e5 audiobasesink: Don't wait on gap events
Don't call wait_event() at all for gap events, as basesink will
end up waiting for the time that the gap event would be rendered
out at the audio device. There's no need to render it at all,
just treat it as a handy point to resync the audio if needed,
let the ringbuffer render silence, and place the next buffer
into the ringbuffer where it belongs.

The only thing we really need to do is make sure the ringbuffer
and clock are running, and wait for preroll.
