From: Ilya Leoshkevich <i...@linux.ibm.com>
Both the report() function as well as the initial gdbstub test sequence
are copy-pasted into ~10 files with slight modifications. This
indicates that they are indeed generic, so factor them out. While
at it, add a few newlines to make the formatting closer to PEP-8.
