Auto test anchors & attached objects
Rename the former tst_declarative to tst_sanity and
extend it with tests to prevent:
a) use of anchors, and
b) multiple attached object instances of the same type.
Anchors are not allowed for two reasons:
- performance (QQuickAnchors is a QObject), and
- to let users relayout delegates (x/y/width/height bindings
can be overridden, anchors not so easily)
Multiple attached object instances (eg. Theme) can easily happen by
accident. "Theme.fooColor" can be used in the control root, but in all
delegate items, "control.Theme.fooColor" must be used instead.
