Badly constructed OSM intersections can create OSRM intersection
views that have no valid turns.
The guidance code for segregated intersections tries to look
ahead to the second intersection to ensure lanes are announced
intuitively.
Currently, OSRM assumes there are always turns at the second
intersection that we should consider. This commit corrects
this assumption so that it can now handle badly constructed
OSM intersections with no turns.
This PR improves routing results by adding support for snapping to
multiple ways at input locations.
This means all edges at the snapped location can act as source/target
candidates for routing search, ensuring we always find the best route,
and not the one dependent on the edge selected.
This change unblocks the osrm-extract debug build, which is
currently failing on a maneuver override assertion.
The processing of maneuver overrides currently has three issues
- It assumes the via node(s) can't be compressed (the failing assertion)
- It can't handle via-paths containing incompressible nodes
- It doesn't interop with turn restriction on the same path
Turn restrictions and maneuver overrides both use the same
from-via-to path representation.
Therefore, we can fix these issues by consolidating their
structures and reusing the path representation for
turn restrictions, which already is robust to the above
issues.
This also simplifies some of the codebase by removing maneuver
override specific path processing.
There are ~100 maneuver overrides in the OSM database, so the
impact on processing and routing will be minimal.

Added CHANGED #4845: Updated segregated intersection identification to Unreleased
When doing the new Lua version refactor we changed the expectation to
use `continue uturn` instead of making a whole circle in the roundabout
as the original test case. This was only the shortest path since there
was no roundabout penalty.
