9d703439f1 pitch: add validate tests
Add pitch tests with different forward and backward playback rates.
Those tests depend on the libSoundTouch version to validate the buffers
checksums. The actual version uses libSoundTouch 2.3.2, use the
`--force-fallback-for=soundtouch` meson option to build using the same
version.

35165da586 pitch: fix multithread accesses
- fully protect accesses to the libsoundtouch API that is not
  thread-safe.
- fully protect accesses to GstPitch members that could be read by a
  downstream query thread while written by an upstream streaming thread
  or a user thread.

9f5bb30d3a pitch: refactor some variables names
- use the `GST_PITCH_GET_PRIVATE` accessor when needed
- rename `out_seg_rate` to `output_rate` to use the same name as the parameter
- rename `seg_arate` to `segment_applied_rate` to improve readability
- apply gst-indent to gstpitch.hh/cc

7f4c0e6fb1 pitch: fix time ratio computation
When changing playing rate, the output segment was not correctly
calculated because the stream time ratio was computed using the previous
input segment rate instead of using the actual rate. This was producing
wrong results for the output segment start and end values.

d82efb47aa pitch: Specify layout as required for negotiation
There are cases where it might negotiate 'non-interleaved' while it
is wrong.
