We use a dedicated pass through the objects in QV4::CompiledData::QmlUnit to determine
which objects are QQmlComponents. We remember their object indices as well as to which
component other objects belong to (if any).

Setting a value on a list property is always just appending to the list instead
of replacing it. Based on that, initializing list properties with multiple
items is done with one binding per item to the same list property. So
myList: [ Item{}, Item{} ]
is mapped to
myList: Item {}
myList: Item {}

Attached properties are implemented similarly to group properties, except that
the object operated on isn't a QQmlValueType from a property (i.e. font) but the
QObject that implements the attached properties.

Signal handlers start out in the parser as binding expressions. A new
SignalHandlerConverter converts the bindings then so that the expression is
turned into a function declaration where the function parameters match the
parameters of the signal.

Binding expressions and QML used to be set up so that they were written
as function closure:
(function(...) {
expression here
})
and then evaluated inside qml scope. With the new setup we do that closure
setup manually now.
For that we have to define a dummy outter "context scope" function in the
codegen, that will later be used to look up the context ids.

This implements support for "font.pixelSize: 24" for example. The representation
in the compile data structure is so that font.pixelSize is short-hand for
font {
pixelSize: 24
}
which means that inside the braces is a complete object initializer. For that
initializer we create a dedicated CompiledData::Object, which however has its
type name empty. When populating the outer instance then, the "font" property
is read as QQmlValueType (a QObject) and instead of creating a new QObject we
use that value type as instance to run the rest of the QML object initializer
(everything in braces).

Collect all references to unknown types after parsing, re-use the existing code
in QQmlTypeLoader to resolve them and finally use the resolved references map
in the QQmlObjectCreator instead of the type name cache directly.

Errors for example in signal declarations are usually reported in the loader
thread, during property cache construction. This patch separates out the
property cache population into QQmlPropertyCacheCreator, runs it from the
loader thread and reduces the QQmlObjectCreator to merely set the properties/bindings/
functions on the object.
This also enables location tracking for signal declarations and their error reporting.

The goal is to parse QML and JavaScript binding expressions/functions in one
go and generate data structures that allow for the parsing to happen in a thread
and the instantiation of the object tree in another thread, just reading from
the generated data structures. This will replace qqmlcompiler and the VME.
This new way of loading QML is currently hidden behind the QML_NEW_COMPILER=1
environment variable. There's lots of work left to fill in the gaps in object
construction, Component support, Component.onComplete, error messages, etc. etc.
