This hopefully prevents buggy compilers from choking on the definitions
outside the class as inconsistent, even though they are consistent.
Also helps developers, as the rather lengthy attribute lists for
C++11 functions does not need to be repeated.
This is in preparation of plastering the QChar API with Q_DECL_NOTHROW.
I had to keep operator== and operator< outside the class because
Clang on OS X 10 didn't find it when called with types implicitly
convertible to QChar.
