Juli Mallett 8714ee5954 Add multiple inclusion guards. Mostly this is for extern.h, which was
included twice by lprint.c, which included both finger.h and extern.h.
finger.h, in turn, includes extern.h.  The redundant include of extern.h
was removed from lprint.c, as part of this change, but the include guards
were added anyway out of spite.
