Adapt to Qt5 meta-object changes

QMetaMethod::signature() has been renamed to methodSignature(), and
returns a QByteArray, not const char *.

Thew new function QMetaMethod::isValid() should be used to check
whether a method is valid (it's a lot cheaper than calling
signature()).

Also use the new QMetaObject::checkConnectArgs() overload that
takes QMetaMethods, not strings, as arguments.

Further improvements can be made by using the new functions
QMetaMethod::name(), parameterCount() and parameterTypes(), but
that will be done in separate commits.
