33696a8aed livesync: Only resend segment if not in single-segment mode
In single-segment mode, the outgoing segment does not change when the
incoming segment changes. We only need to resend the segment if we got
flushed or deactivated.

570eb7463a livesync: fix late-threshold property min value
The code is handling 0 as "always over threshold" but it was not
possible to set the property to 0.

42385c81be Add livesync plugin
It attempts to produce a (nearly) gapless live stream by synchronizing
its output to the running time and forwarding the next input buffer if
its start is (nearly) flush with the end of the last output buffer.

If the input buffer is missing or too far in the future, it duplicates
the last output buffer with adjusted timestamps. If it is operating on a
raw audio stream, it will fill duplicate buffers with silence.

If an input buffer arrives too late, it is thrown away. If the last
input buffer was accepted too long ago (according to `late-threshold`),
a late input buffer is accepted anyway, but immediately considered a
duplicate. Due to the silence-filling, this has no effect on audio, but
video gets a "slideshow" effect instead of freezing completely.

The "many-repeats" property will be notified when this element has
recently duplicated a lot of buffers or recovered from such a state.
