Remove time_per_frame, it's too inaccurate. Fix convert for -1 values. Use scaling to convert samples to time. Fix segment handling. Fix seeking. Fix buffer clipping (not yet enabled) Protect the WildMidi library with the object lock to avoid races when changing properties. Fix offsets on output buffers, for raw audio the offset contains the sample position not byte position. Add better DISCONT handling. Fixes #519001

* Wrapper element for libtimidity. This element works in pull
|
|
* based mode because that's essentially how libwildmidi works.
|
|
* We create a libwildmidi stream that operates on the srcpad.
|
|
* The sinkpad is in pull mode.
