util: Allow IN4_IS_* macros to operate on untyped addresses
The IN4_IS_*() macros expect a pointer to a struct in_addr. That
makes sense, but sometimes we have an IPv4 address as a void * pointer
or union type which makes these less convenient. Additionally, this
doesn't match the behaviour of the standard library's IN6_IS_*()
macros on which they're modelled, nor our own IN4_ARE_ADDR_EQUAL().
