QHostAddress: fix assignment operators

QHostAddress allowed assignment from a QString, but the respective
constructor is explicit, and rightfully so. So it does not make
sense that the assignment operator is provided, because of the
asymmetry caused between

   QHostAddress addr = funcReturningQString(); // ERROR
   addr              = funcReturningQString(); // OK (until now)

By the same token, since SpecialAddress is implicitly convertible
to QHostAddress, provide the missing assignment operator from that
enum.

Add tests, rewriting the _data() function to use the enum instead
of an int to pass SpecialAddress values, and to test !=, too.

Added setAddress(SpecialAddress), since a) it was missing and
b) to share code between the ctor and the assignment operator.
