From: Florian Fischer <florian.fl.fischer@fau.de>
Date: Wed, 6 May 2020 16:56:32 +0200
Subject: 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
