Allow declarations such as:
enum MyEnum {
Value1 = 1,
Value2
}
Not all features of C++ enums are supported. Specifically, we don't yet
allow:
* Negative numbers (Value1 = -1)
* Assignment of other values (Value2 = Value1)

Value2
}
Grammar changes done by Simon Hausmann.
[ChangeLog][QtQml] Enums can now be declared directly in QML.

We also tie this up to the existing skeletal "const" support so that they
are also checked for duplicate declarations.
While we do that, change from using a boolean to an enum so we make the scope of
a declaration a little more easily comprehensible.

Declarations such as
property Namespace.Item foo
or
property list<Namespace.Item> foo
would get rejected by the grammar due to the lack of productions. This
is now encapsulated in the UiPropertyType, which used to be merely an
identifier but is now changed to produce a UiQualifiedId - the same type
that's also used for MyNamespace.Item { ... } object declarations for
example.

The grammar was not permitting to write
default property list<Item> myChildren;
and instead developers had to work around it with an alias
property list<Item> myChildrenData;
default property alias myChildren: myChildrenData
which is not nice. Fortunately this is easy to fix in the grammar.

From Qt 5.7 -> LGPL v2.1 isn't an option anymore, see
http://blog.qt.io/blog/2016/01/13/new-agreement-with-the-kde-free-qt-foundation/
Updated license headers to use new LGPL header instead of LGPL21 one
(in those files which will be under LGPL v3)

Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.

The grammar did not allow for the declaration of
readonly property QtObject foo: QtObject { ... }
and it required a workaround through an alias:
readonly property alias foo: _foo
property QtObject _foo: QtObject { ... }
This was merely a glitch in the grammar, I see no reason not to support this.
The semantics are like a const pointer in C++, the property itself is read-only
but the object pointed to has per-property defined read/write semantics.

This introduces Singleton support for QML (Composite Singleton). For
now, the Singleton support is only availabe for QML types in modules
or (remote and local) directories with qmldir file. However, in the
future this support may be expanded to arbitrary QML file imports
without by leaving out the qmldir requirement.
You define a QML type as a Singleton with the following two steps:
1. By adding a pragma Singleton to a type's QML file:
pragma Singleton
The pragma and import statements can be mixed and their order does
not matter. Singleton is the only supported pragma for now. Others
will generate errors.
2. By specifying a qmldir file for the directory of your imported
type and prepending the type with "singleton" keyword as follows:
singleton TestTypeSingleton TestTypeSingleton.qml
Alternatively you may specify a qmldir file for a module and specify
your type as a singleton as follows:
singleton TestTypeSingleton 1.0 TestTypeSingleton.qml
Composite Singletons may be included in a module and may be used with
a local namespace qualifier when imported with:
"import xxx as NameSpace"
A singleton instance is created at first use and stored into the
QmlEngine (one instance per engine) and eventually released by the
engine's destructor.
CompositeSingletonType has a dual nature and will return true to both
isComposite() and isSingleton() calls. In most cases its enough to
check for just isComposite() or isSingleton(). However, there is a
isCompositeSingleton() available as well.
I used "qlalr --no-debug --no-lines --qt qqmljs.g" to generate the
qqmljsparser and qqmljsgrammar files from qqmljs.g.
Unit tests are included.
