927788a0b0 Move vari-speed into backend (resample ports)
Previously Ardour used a /local/ per track vari-speed mechanism.
Now that the disk-reader is a latency-compensated processor, the speed
of each disk-reader would need to be maintained locally, offset by each
disk-reader's output latency. Furthermore each disk-reader may
produce a different number of samples, depending on its global alignment.

This commit introduces port-data resampling directly at the engine-level:
Up/down-sample all input ports at the beginning, and down/up-sample output
port-data using the inverse ratio at the end of the session's process
cycle.
The session itself is unaware of the speed-change, and only needs to
handle transport speeds {-1, 0, +1}.

This also allows for aligned cue-monitoring and vari-speed recording,
and also pitch-shifts synthesized MIDI along.

e6c8f104d1 Fix loading sessions w/new tempo-map.
Newly constructed sessions don't save "Tempo-start" property.
If there's no "start" node, _legacy_bbt is never explicitly set and
the default c'tor is used, which sets bar = 1.
The test for legacy session checks bar != 0.

All new sessions were processed with fix_legacy_session(), which breaks
the tempo-map and makes the session not loadable (duplicate Tempo).
