Per https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/xbd_chap04.html:
"A pathname that begins with two successive slashes may be interpreted
in an implementation-defined manner, although more than two leading
slashes shall be treated as a single slash."
So more than 2 leading slashes are supposed to be folded into one,
which our dirname neglected. Fix that.

Make kill -V and kill -l exit immediately, thus stopping to
print "not enough arguments" accidentally.

Take the opportunity to follow FreeBSD's and Linux's lead in recasting
macro inline code as calls to static inline functions. This allows the
macros to be type-safe. In addition, added a lower bound check to the
functions that use a cpu number to avoid a potential buffer underrun on
a bad argument. h/t to Corinna for the advice on recasting.
