add property 'min-keyframe-distance'

The following patches add the properties 'min-keyframe-distance' and
'keyframe-placement-mode'.

The spec doesn't document it, but min_kf_distance can only be 0 or equal to
max_kf_distance, otherwise the encoder will not init.[1]

Does it make sense property 'fixed-keyframe-distance' instead? Or should I
leave the 'min-keyframe-distance' if in the future it can be used with a
different combination of values?
