Currently _setsockopt (& _getsockopt) only handles integers.
todo: fails with e.g. SO_RCVTIMEO/SO_SNDTIMEO

if (!Number.isInteger(flagValue)) {
	throw new Error('flagValue must be an integer')
}

The native code would have to be adapted to create the appropriate structs for selected flags.

This could be done using shared-structs.
