- Reorganize patches by feature/bug per packaging guidelines (#225691) - Move the following files from patches to source files: linux.dbus-example, linux, Makefile.dist, dhcp4client.h, libdhcp_control.h - Compile with -fno-strict-aliasing as ISC coding standards generally don't agree well with gcc 4.x.x
