Brian Somers 75240ed178 Cosmetic (no functional changes):
o   Add missing $Id$s
o   Move extern decls from .c -> .h files
o   Staticize
o   Remove #includes from .h files
o   style(9)ify includes
o   bcopy -> memcpy
    bzero -> memset
    bcmp -> memcmp
    index -> strchr
    rindex -> strrchr
o   Move timeout.h -> timer.h (making it consistent w/ timer.c)
o   Add -Wmissing-prototypes
