Declarative: Fix MSVC and g++ warnings

Potentially severe:
- Fix int/bool mismatches
- Use of uninitialized variable
- Do connectionMask shift operations in 64bit
- Enum type mismatch for QLineControl::EchoMode

Various:
- class/struct mismatches
- UnhandledEnumeration values
- Unused variables
- Constructor initialization order
