a8cf2aa4f9 fix required-sample count for cubic interpolation. 
I have not proved if the iterative process in
CubicInterpolation::interpolate() is identical to
(nframes * fabs(_actual_speed)), however ceil()
of it is empirically always larger.
Also, the cubic interpolation needs +2 samples.

Ardour3: Too close to call :)

a3a398242b tigten LTC Slave resolution. 
The reason for this is that the LTC generator uses the slave's
resolution as watermark for max-drift, resync. A possible drawback:
session-process will force silent rolls if the delta is larger
than the resolution. LTC has a carrier freq of ~2kHz, choosing
half of that seems a good compromise.
