[OSRM-talk] Extended graph output file

The edge-expanded graph already gets written to disk; this was introduced
in the following commit:

https://github.com/Project-OSRM/osrm-backend/commit/e45656e5bfb0b61a2859f0c754e66322996f1640

which is not yet in the latest release, so you have to build from the
develop branch.


If you search for ebg you will see related files:

Word of caution: the serialization in OSRM is done by just dumping internal
datastructures in binary format.
This is neither a portable between operating systems, compilers or even
standard libraries, nor a stable format, and in particular not intended to
be read from other programs.
You would have to get the data structure layout right, in order to make use
of the ebg file from other programs.
