This change takes the existing typedefs for weight, duration and
distance, and makes them proper types, using the existing Alias
functionality.
Primarily this is to prevent bugs where the metrics are switched,
but it also adds additional documentation. For example, it now
makes it clear (despite the naming of variables) that most of the
trip algorithm is running on the duration metric.
I've not made any changes to the casts performed between metrics
and numeric types, they now just more explicit.
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.
Regardless of any copy elision on the returned pair value, the
duration and distance results are always copied.
Fix this by passing rvalue references to std::make_pair.
In situations where there is not a valid source or target phantom
node (e.g. when snapping to an edge with a zero weight), a
heap assertion will fail in the MLD alternative search code.
We fix this by checking for empty heaps before proceeding with
the search.
Fixes#5788
Table queries where source and destination are phantom nodes
on the same one-way segment can fail to find valid routes.
This is due to a bug in the MLD table generation for the
special case where the query can be simplified to a
one-to-many search.
If the destination is before the source on the one-way segment,
it will fail to find a route.
We fix this case by not marking the node as visited at the start,
so that valid paths to this node can be found later in the search.
We also remove redundant initialization for the source
node as the same actions are performed by a search step.

For the MLD algorithm we can partition the NodeID range into boundary
and non-boundary nodes. Since there are only we boundary nodes we can
use the ArrayStorage for those yielding much faster query times.
Rename module partition to partitioner.
This cultivates naming used in existing modules like extractor,
customizer, etc. - noun vs verb (word partition is both though).
