eliminate unneeded dependencies on public headers

- Remove unneeded dependencies from libqtappfw public
headers, specifically MessageEngine and Message
hierarchy header files, in preparation for refactoring
work on these areas.
This change helps shield client apps from the
upcoming changes in the library, and highlight the
separation between the library's core and the various
modules providing public interfaces to those apps.

- Make MessageType an scoped enum to fwd declare it.

- Update Copyright statement on files updated by
this patch.
