Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

- *
- * Changes:
- *	Alan Cox		Reformatted, removed sound_mem usage, use normal Linux
- *				interrupt allocation. Protect against bogus unload
- *				Fixed to allow IRQ > 15
- *	Christoph Hellwig	Adapted to module_init/module_exit
- *	Arnaldo C. de Melo	got rid of check_region
- *
- * Status:
- *		Untested
