Debug packages are fairly useless currently because the soucre files needed for stepping through code etc are not packaged with them. This patch adds the needed source files to the debug package and adjusts the debug info to look at the /usr/src/debug/ directory for them rather than the build location. This requires using the "debugedit" program which is provided as part of the RPM sources.
