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
