without creator dependencies and made it compile with debugging
helpers.

When multiple threads share the Bind instance in a Document and do
lookup on the objects contained inside, that may trigger a new object
creation in some situations - which needs to be synchronized.

The Qt4ProjectManager now uses metacalls to inform the QmlJSModelManager
about the project data.

Link now caches imports. That means importing the same library (say, Qt)
from more than one file no longer creates an importing namespace for
each one. Instead, a single one is created for the instance of Link.

To make this work, the type environment in ScopeChain has been given its
own type: Interpreter::TypeEnvironment. That has the added benefit of
being able to carry meta-information about imports. You can use
TypeEnvironment::importInfo(qmlComponentName) to get information about
the import node that caused the import of the component.

Don't use QMultiHash::values(key), it rebuilds the values list from
scratch for each lookup.

We don't want people modifying the shared component chain on a
const Context *.

 * Fix all warnings about non-explicit constructors except for those
   in 3rdparty code.

Now that Contexts are cached, it needs to be copyable. However, the
ScopeChain has a QmlComponentChain member that owns resources and didn't
have a correct copy constructor or copy assignment operator.

I've made QmlComponentChain non-copyable and store a shared pointer to
an instance instead, as it will generally not change for a given
context.

* If possible, create LookupContexts through SemanticInfo; it caches the
  linked Context and will be faster.
* Contexts now own their Engine.

The builtin QML plugins require to be imported with the full uri, i.e.
import Qt.labs.particles 1.0
so setting the import path to imports/Qt/labs and doing
import particles 1.0
is not supposed to work. (see QTBUG-11139)

This change adjusts qmldump to take an import path *and* the import uri,
so it will be able to dump the type information for these plugins.

The QColor constructor prints a warning if the string it gets passed
isn't a known color name. Also, it doesn't know about the alpha value
in strings like "#ff00ff00".
