c.h #includes a number of core libc header files, such as <stdio.h>. There's no point in re-including these after having read postgres.h, postgres_fe.h, or c.h; so remove code that did so. While at it, also fix some places that were ignoring our standard pattern of "include postgres[_fe].h, then system header files, then other Postgres header files". While there's not any great magic in doing it that way rather than system headers last, it's silly to have just a few files deviating from the general pattern. (But I didn't attempt to enforce this globally, only in files I was touching anyway.) I'd be the first to say that this is mostly compulsive neatnik-ism, but over time it might save enough compile cycles to be useful.
