[erts, kernel] reuseaddr/reuseport/exclusiveaddruse support/fixes
* Introduce socket option 'reuseport' which may or may not have
load balancing.
* Introduce socket option 'reuseport_lb' with load balancing.
* Introduce socket option 'exclusiveaddruse'. This socket option is
Windows specific and will silently be ignored on other systems.
* Change behavior on Windows so that SO_REUSEADDR is only set if
both 'reusaddr' and 'reuseport' have been set. This since
SO_REUSEADDR on Windows behaves as BSD behaves if both SO_REUSEADDR
and SO_REUSEPORT have been set.
