make the whole project more python idiomatic
* rename src directory to allocbench * make global variable names UPPERCASE * format a lot of code using yapf * use lowercase ld_preload and ld_library_path as Allocator members * name expected Errors 'err' and don't raise a new Exception * disable some pylint messages
