net: net.lo, lots of scripts
The program function in depend blocks is now able to search paths by
itself. If passed multiple arguments or multiple calls, at least one of
the arguments passed must be a program or a shell builtin (eg ip built
into busybox). If a qualified path is specified, only that path will be
checked, otherwise it will be checked as a builtin, then $PATH will be
checked for the named binary (via type).
