robert 27ec88afb5 - Let their manual pages show the reader that the bzero(3) and
bcopy(3) functions are prototyped in <strings.h> and not in
   <string.h> anymore.
 - Add a sentence about that to the respective HISTORY sections.
In the C source files:
 - Include <string.h> or <strings.h> depending on what function
   is to be compiled.
 - Use ANSI-C function definitions.
