Speed controller adaptation

Description
With the speed controller adaptation, any speed controller oscillation can be suppressed.
Two adaptation methods are available, namely free Kp_n adaptation and speed-dependent
Kp_n/Tn_n adaptation.
Free Kp_n adaptation is also active in "operation without encoder" mode and is used in
"operation with encoder" mode as an additional factor for speed-dependent Kp_n adaptation.
Speed-dependent Kp_n/Tn_n adaptation is only active in "operation with encoder" mode and
also affects the Tn_n value.
