Moved the GeometryCompressor's free_list_maximum into a member variable of the class.
(+UniqueNumber() commented out since it is not being used anywhere in all of OSRM)
There was absolutely no need for free_list_maximum to be a static variable and it caused major issues in my code.
Short description:
- I ran osrm-prepare's Prepare().Process(..) function in my own code multiple times for multiple files
=> After the first file is done, free_list_maximum is still on the same size, but a new GeometryCompressor will start at a size of 100 again.
=> Indices broken.
