This has two patches. First it moves interface.c to libbb (it is
support code after all). It also contains a patch from Larry Doolittle that removes two instances of "strlen([^)]*) *- *1", un-shadows two variables, relaxes requirement for a sprintf(3) that returns number of bytes written, and eliminates a duplicate subroutine.
