Expand case class `IncOptions` in binary compatible way so we can have
better control of methods like `unapply` when new fields are added.
Great precaution has been taken to ensure that this commit doesn't break
binary compatibility. I took a dump of javap output before and after
this change for both the class and it's companion object.

The first diff shows that there are just more static forwarders defined
for top-level companion object and that is binary compatible change.
The second diff shows that there are just a few minor differences in
order in which `unapply`, `apply` and bridge method for `apply` are
defined. Also, there's a new `toString` declaration. All those changes are
binary compatible.
All methods that are generated for a case class are marked as deprecated
and will be removed in the future.
