Qt allows string-based key/value pairs to be inserted into QObject class
definitions. E.g.,
class Q : public QObject
{
Q_OBJECT
Q_CLASSINFO( "key1", "value1" )
};
The class info is accessible in the meta-object system. See:
http://qt-project.org/doc/qt-4.8/qmetaclassinfo.html
For more information.
This patch adds the API to access these key/value pairs from the
QtIndex. The values are stored in a single block in the PDOM record for
the QObject.
The API returns the value for a given key if it is found in the receiver
QObject or any of its base classes. The API returns the first such
value that is found.
This patch also adds a test case for this functionality.

The Qt meta-object system allows C++ enums to be added as simple enums
and as flags. There is more detail at:
http://qt-project.org/doc/qt-4.8/qobject.html#Q_ENUMS
and http://qt-project.org/doc/qt-4.8/qflags.html
This patch adds IQEnum to the QtIndex. IQEnums are contained in
IQObjects and therefore are accessed with the IQObject.getEnums.
An IQEnum holds its name, enumerators, and a boolean indicating whether
the instance represents a Qt flag.
A Qt flag is an enum where the enumerators are intended to be used with
bitwise operations. The Q_DECLARE_FLAGS macro is used to introduce a
type-safe container for the flags.
This patch also adds unit tests for this new functionality.

This uses the new PDOMASTProcessor extension point to create a
Qt-specifc PDOMLinkage. This initial version of the linkage only stores
QObjects and their base classes. Later commits will fill out other
details and introduce classes that use this data for things like Content
Assistance and Codan checking.
This patch introduces the following:
1) QtIndex: This is an index that provides access to Qt-specific data.
The index is mostly a wrapper on the CDT's existing IIndex, but it
provides very specific information about the Qt elements. The only data
that can be accessed from the QtIndex (in this patch) is a QObject and
the QObject's that appear in its base class specifier list.
2) QtPDOMLinkage: This linkage is implemenated as an extension of the
PDOMCPPLinkage. In some cases it adds references to Qt names from the
C++ bindings.
3) Test suite: The test suite has some base classes for parsing the Qt
source code. The only test case is for the simple functionality that is
being added in this patch -- examining the base class specifier list of
QObjects.
These areas will be extended in later patches.
