  Log Message:
  -----------
  node tool fixes:
- fix OTFR support (fixes #5327.16)
- smaller snap tolerance for geographic CRSs (fixes #5661)
- use different snapping epsilons in QgsVectorLayer::snapToGeometry() for
  layers with geographic and projected crs.
- [API] enhancements (to fix #5661):
 * QgsGeometry::closestSegmentWithContext: allow passing of segment snapping
   epsilon
 * QgsPoint::sqrDistToSegment: allow assing of segment snapping epsilon
 * QgsMapLayer::crs() add "const"
