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

-This benchmark measures the clock cycles used by malloc.
-It tries to spread the spawned thread on all cores exept the first one.
