Run astyle on top-level sources.

The sources have ugly whitespace. Run astyle on them, ignoring those
in usb_lib/. Astyle version 2.01 (2.01-1 on Ubuntu 12.04) options were:

--indent=spaces=4
--style=java
--indent-namespaces
--pad-oper
--pad-header
--unpad-paren
--align-pointer=name
--indent-preprocessor
--lineend=linux
