b9a4c322a7 Add ability to debug routing graph visually by dumping 
annotated GeoJSON during processing.

6228412e61 Enable just-before-contraction updates to edge weights. For small 
datasets, this enables things like traffic-based updates in the
shortest possible processing turnaround time.

63ba6018f3 Cache the node priorities between runs 
This speeds up processings on the same dataset significantly by creating
a .level file that saves the level in which a node was contracted.
It removes the need for expensive recomputation of priorities and such.

Use with care! Running `osrm-extract` again will invalidate .level
files.

809bdb7c1f Fixes version generation, no longer derives version on git tags. 
We were stuck on the 4.5.0 tag from develop, since we searched for the
latest tag, but release tags are done on the master branch.

This commit rips out all the code for deriving the version on git tags.

Instead, we define major, minor, and patch versions in the CMakeLists
and then pass it on to:

- the `libosrm.pc` `pkg-config` file

- a `version.hpp` header that makes use of the preprocessor's string
  concatenation to provide an easy way for generating version string
  literals such as "v4.8.0".

That is, in the source code please now use the following defines:

    #define OSRM_VERSION_MAJOR "@OSRM_VERSION_MAJOR@"
    #define OSRM_VERSION_MINOR "@OSRM_VERSION_MINOR@"
    #define OSRM_VERSION_PATCH "@OSRM_VERSION_PATCH@"

    #define OSRM_VERSION "v" OSRM_VERSION_MAJOR "." OSRM_VERSION_MINOR "." OSRM_VERSION_PATCH

6e6b38e8e9 Revert the usage of TBB's iterator pair taking overloads. 
This reverts the range based overload usage introduced in @6b2bf495.

Old TBB versions do not provide the range overloads.

9231335eef Use Intel TBB's parallel_sort even for nested parallelism. 
TBB has a global task scheduler (that's one of the reason TBB is not
linked statically but dyanmically instead). This allows control over all
running threads, enabling us to use nested parallelism and the scheduler
doing all the task allocation itself.

That is, nested parallel execution such as in

    parallel_for(seq, [](const auto& rng){
      parallel_sort(rng);
    });

is no problem at all, as the scheduler still claims control over the
global environment.

Therefore, use `parallel_sort` Range overload where possible.

f10fb77a81 Ownership: vector already owns, no need for wrapping in unique_ptr. 
Removes the pointless `std::unique_ptr<std::vector<T>>` usage,
as a `std::vector` already owns its resources and manages them.

Results in one indirection less (hint: good).

b526cadebd Initial version of core ch 
This improves preprocessing times in favour of worse query performance.
Core size can be set over the --core parameater, default is the old
behaviour to fully contract the graph.
