Log message:
ping(8): improve "-i wait" parsing and error-checking code
- Never accept negative values.
- Cap the interval at UINT_MAX seconds to avoid strange rounding
behavior at the end of the input range.
- Use error messages that resemble other parts of the tree where we
are able to use strtonum(3).
- Leverage modf(3) for cleaner code.
- Call it "-i interval" to avoid accidental visual similarity to
"-w maxwait".
With input from cjeker@, kettenis@, kn@.
