Moritz Kobitzsch 15c8fd326f Remove assertions that could be triggered by bad data. (#3469) 
When two consecutive nodes have identical coordinates, there is no valid
bearing.  For now, make equal nodes have bearing 0.

Full fix still needs to be done via https://github.com/Project-OSRM/osrm-backend/issues/3470.

Moritz Kobitzsch 5e167b8745 Turn Angles in OSRM were computed using a lookahead of 10 meters. 
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.

Daniel Patterson ec02cdc4cc Use mmap instead of read - it's a lot faster here. 
Also clean up construction of STRONG_TYPEDEF so that it can be
packed properly in structs (this explains all the () -> {}) changes
here.

Patrick Niklaus 30a9bc3179 Fix mathematical assumptions in StaticRTree 
StaticRTree now uses projected coordinates internally. That means we can
use a euclidean distance measure (squared distance) for sorting the
query queue.

Daniel J. Hofmann ef171f3acd Properly use typed math constants instead of impl. specific hacks 
PI is not in the stdlib, neither is 1/pi, pi*2 and so on. Instead
of relying on implementations providing these, use properly typed
math constants.

Main benefits:
- portable and
- returns constexpr, for compile-time computation
