fixes after peer review:
renamed disable to relaxed
make parameters private
default type to 1
enabled method checks backend created
servo range initialised in init method
contrain rate-desired during position control
use set-output-limit instead of set-safety-limit
release_length accepts rate
Due to the way the headers are organized changing a single change in
an AP_Notify driver would trigger a rebuild for most of the files in
the project. Time could be saved by using ccache (since most of the
things didn't change) but we can do better, i.e. re-organize the headers
so we don't have to re-build everything.
