conf-parser.h pulls in a lot of other headers as needed by all the macros it defines. We can't easily move the implementations of these macro to conf-parser.c, so let's instead introduce conf-parser-forward.h with just the stuff in it needed by other header files. We'll make use of this when cleaning up includes to only include the minimal parts of conf-parser.h that are required by other headers without pulling in the kitchen sink.
