[Python-3000] Moving files around

[Georg Brandl]

There are a few files which seemingly don't belong in their subdirectories:

* Python/bltinmodule.c -> Modules
* Python/sysmodule.c -> Modules
* parts of Python/import.c -> Modules/impmodule.c

* Python/traceback.c -> Objects

* Modules/getpath.c -> Python
* Modules/getbuildinfo.c -> Python
* Modules/python.c -> Python
* Modules/main.c -> Python

However, I guess moving them would cause much more confusion for those
merging changes between branches than for those having to find the files
in the wrong directory in the first place ;)
