It always bothered me a bit that unit-name.[ch] contains so many definitions that aren't really have much to do with unit nameing, for example all the unit state definitions. With this patch unit-name.[ch] is split into two: the file now contains only the unit naming related operations, and everything else is split out into a new set of files unit-def.[ch]. That's mostly unit state stuff as well as dbus path and interface name operations. No functional changes. This just moves code around. (Note as both .c files include each other's headers this doesn't make the build simpler or anything. All it does is make the C files a bit shorter, and medicate my pretend OCD)
