From stxxl FAQ: "you should not share a data structure between
threads (without implementing proper locking yourself)."
The access to name_char_data can be implicitly parallelized
if _GLIBCXX_PARALLEL is defined and invalidate local-thread iterators.
Removes CompressedEdges from the extractor and shared data format by
directly serializing vectors of node ID's, forward weights and reverse
weights for each node-based-edge
Refs #2575
This PR adds more advanced coordinate extraction, analysing the road
to detect offsets due to OSM way modelling.
In addition it improves the handling of bearings. Right now OSM reports
bearings simply based on the very first coordinate along a way.
With this PR, we store the bearings for a turn correctly, making the
bearings for turns correct.
Changes the internal representation of compressed geometries to be a
single array shared between forward and reverse geometries that can be
read in either direction. Includes a change on
extractor::OriginalEdgeData to store via_geometry ids that indicate
which direction to read the geometry for that edge based edge.
Closes#2592
Takes a stricter aproach for whitelisting / blacklisting restrictions:
- uses `restriction=`
- uses more specific `restriction:<type>=`
- uses `except=<type>` to invert
Where `type` is the type of transportation to restrict, e.g. `motorcar`.

With @karenzshea's name / ref split (ref. #2857) in master we want to
make use of it and reduce `NewName` instructions when ever possible.
This is a first step towards #2744 by using the already existing name
change heuristic from the extractor now in post-processing as well.
Limitations: at the moment we don't have the `SuffixTable` in
post-processing; this would require us serializing and subsequently
deserializing the table, passing it through from the profiles to the
API.
Before we only worked on subsequent quick turns, as in:
`right, right` keeps the user on the rightmost lanes.
This changeset modifies the logic to work on any subsequent steps
that are "quick" and have lane information we can constrain later.
Because we do not have a from-lane => to-lanes mapping we take the
lanes left and right of the turn lanes into account when heuristically
assigning the leftmost / rightmost lanes.
There are some edge cases where this still does not give us the optimal
solution but it gets close to what is actually possible at the moment
without having a lane mapping in post-processing.
