Some linkers can determine that we don't use any symbols from the
QtQmlModels and QtQmlWorkerScript libraries in the respective plugins
and avoid to link the libraries into the plugins. That means, when
loading the plugins, the types are not registered. We avoid that by
adding a debug message that accesses a symbol of the library to each
plugin.

Previously it was impossible to determine whether a WorkerScript has
been fully initialized. This commit introduces a ready property that
allows outside Components to determine whether it is safe to send
signals.

Using this technique we can automatically register all necessary
revisions and minor versions of a type, using the metaobject system.
This greatly reduces the potential for mistakes and resulting
incompatibilities between versions of imports.
We assume that for each type we need to register all revisions of its
super types and its attached type, and that the revisions match. That
is, if you import version X of type A, you will also get version X of
its attached type and of any super types. As we previously didn't take
these dependencies into account when manually registering the types, a
number of extra revisions are now registered for some types.
Potentially, we can now generate the qmltypes files at compile time,
using moc.
