fe2ae2c0f7 scaletempo: Ensure to reinit buffers whenever they were not allocated yet
That is, whenever we go through start/stop we have to ensure that on the
next opportunity the buffers are reallocated again. Otherwise the
buffers might be NULL because the element was reused with the same
configuration as before (i.e. set_caps() wouldn't have reinited the
buffers).

2dee0e385f scaletempo: S16 uses S32 temporary buffers, float/double their own type
Make sure to allocate not only a S16 buffer for S16 but a twice as big one to
hold S32.

903c431d6d scaletempo: Free the various buffers in GstBaseTransform::stop()
Previously we leaked them completely, but as they're specific to the caps
freeing them in stop() instead of finalize() makes most sense.

ae3b903019 scaletempo: Fix handling of rate < 0
We have to reverse all samples in a buffer before processing them to properly
have continuous data from one buffer to another. As a result we will have a
negative applied rate and a rate of 1.0.

Also make sure that input buffers are correctly clipped to the segment,
otherwise our calculations are going to go wrong.

Also copy over the segment event's sequence number to the output segment while
we're at it.

e552bd484f scaletempo: use gst_element_class_set_static_metadata()
where possible. Avoids some string copies. Also re-indent
some stuff. Also some indent fixes here and there.

2d72ec153a scaletempo: properly update new segments
Scaletempo was missing an update of 'stop' in
new segment parameters when pushing it downstream,
which caused files to end earlier when rate < 1.

Fixes #599903
