Port to pointer-to-member-function connection syntax

Rename overloads that would cause conflict and require explicit overloa
resolution via QOverload:

- Q*Reply::error -> errorOccurred (equivalent to QNetworkReply)
- Q*Engine::error -> errorOccurred (for consistency, even if no overloa
- Q*Manager::error -> errorOccurred (ditto)
- QDeclarativeGeoMap::copyrightChanged -> copyrightImageChanged

As a drive-by, change QString value parameters to const references.
