Move Qt Core examples under a common subdirectory

Qt Core examples were scattered into several subdirectories under
qtbase/examples. This caused an issue with the example manifest
file generated by QDoc; it expects to find all examples under a
common directory in order to produde correct paths to the example
.pro files. Qt Creator will not find the examples without a valid
manifest file.

This change moves the examples and edits the documentation files
accordingly.

-    \example customtype
-    \title Custom Type Example
-
-    \brief The Custom Type example shows how to integrate a custom type into Qt's
-    meta-object system.
-
-    Contents:
-
-    \tableofcontents
-
-    \section1 Overview
-
-    Qt provides a range of standard value types that are used to provide
-    rich and meaningful APIs. These types are integrated with the meta-object
-    system, enabling them to be stored in QVariant objects, written out in
-    debugging information and sent between components in signal-slot
-    communication.
-
-    Custom types can also be integrated with the meta-object system as long as
-    they are written to conform to some simple guidelines. In this example, we
-    introduce a simple \c Message class, we describe how we make it work with
-    QVariant, and we show how it can be extended to generate a printable
-    representation of itself for use in debugging output.
-
-    \section1 The Message Class Definition
-
-    The \c Message class is a simple value class that contains two pieces
-    of information (a QString and a QStringList), each of which can be read
-    using trivial getter functions:
-
-    \snippet customtype/message.h custom type definition
-
-    The default constructor, copy constructor and destructor are
-    all required, and must be public, if the type is to be integrated into the
-    meta-object system. Other than this, we are free to implement whatever we
-    need to make the type do what we want, so we also include a constructor
-    that lets us set the type's data members.
-
-    To enable the type to be used with QVariant, we declare it using the
-    Q_DECLARE_METATYPE() macro:
-
-    \snippet customtype/message.h custom type meta-type declaration
-
-    We do not need to write any additional code to accompany this macro.
-
-    To allow us to see a readable description of each \c Message object when it
-    is sent to the debug output stream, we define a streaming operator:
-
-    \snippet customtype/message.h custom type streaming operator
-
-    This facility is useful if you need to insert tracing statements in your
-    code for debugging purposes.
-
-    \section1 The Message Class Implementation
-
-    The implementation of the default constructor, copy constructor and destructor
-    are straightforward for the \c Message class:
-
-    \snippet customtype/message.cpp Message class implementation
-
-    The streaming operator is implemented in the following way:
-
-    \snippet customtype/message.cpp custom type streaming operator
-
-    Here, we want to represent each value depending on how many lines are stored
-    in the message body. We stream text to the QDebug object passed to the
-    operator and return the QDebug object obtained from its maybeSpace() member
-    function; this is described in more detail in the
-    \l{Creating Custom Qt Types#Making the Type Printable}{Creating Custom Qt Types}
-    document.
-
-    We include the code for the getter functions for completeness:
-
-    \snippet customtype/message.cpp getter functions
-
-    With the type fully defined, implemented, and integrated with the
-    meta-object system, we can now use it.
-
-    \section1 Using the Message
-
-    In the example's \c{main()} function, we show how a \c Message object can
-    be printed to the console by sending it to the debug stream:
-
-    \snippet customtype/main.cpp printing a custom type
-
-    You can use the type with QVariant in exactly the same way as you would
-    use standard Qt value types. Here's how to store a value using the
-    QVariant::setValue() function:
-
-    \snippet customtype/main.cpp storing a custom value
-
-    Alternatively, the QVariant::fromValue() and qVariantSetValue() functions
-    can be used if you are using a compiler without support for member template
-    functions.
-
-    The value can be retrieved using the QVariant::value() member template
-    function:
-
-    \snippet customtype/main.cpp retrieving a custom value
-
-    Alternatively, the qVariantValue() template function can be used if
-    you are using a compiler without support for member template functions.
-
-    \section1 Further Reading
-
-    The custom \c Message type can also be used with direct signal-slot
-    connections.
-
-    To register a custom type for use with queued signals and slots, such as
-    those used in cross-thread communication, see the
-    \l{Queued Custom Type Example}.
-
-    More information on using custom types with Qt can be found in the
-    \l{Creating Custom Qt Types} document.
