QCursor support for Symbian OS

Reviewed-By: Jason Barron
Reviewed-By: Alessandro Portale

    Summary:
    QT_NO_CURSOR is now not defined for symbian builds
    Existing QCursor APIs are all supported
    New public API, QApplication::setNavigationMode, to allow the navigation
    mode to be set. I.E. on an S60 3.2 phone, some applications will want a
    virtual mouse cursor (web browser), while others are designed for keypad
    navigation.
    Symbian HAL is used for detecting input capabilities.

    Fix DND, code cleanup & comment

    QCursor visibility now uses a refcount, and is called from DND and the
    setNavigationMode so they are both simpler and don't interfere with each
    other.

    QApplication::setNavigationMode

    New public API for configuring cursor/keypad navi style.
    This links in with ongoing work on the 4-way keypad navi branch, but
    2-way and 4-way modes both act as 2-way mode until that is integrated
    Some of the demos/examples have cursor switched on (those that were not
    usable with keypad)

    Virtual mouse support for non touch, non mouse phones (tested on N78)

    add *.d and .metadata (carbide debug file / workspace dir) to .gitignore

    System pointers are unavailable when using sprite workaround, so the
    system cursor shapes are compiled into qtgui as resources.
    MAC port does this also for shapes that aren't standard on the MAC.

    Refactor Drag'n'Drop to use QCursor

    Add test case to check all system cursor shapes

    Simply a mainwindow containing a label widget for each cursor shape,
    with the cursor property set appropriately

    QCursor(QBitmap,QBitmap) supported

    Fixed problem with the image & mask being inverted when using the
    QCursor constructor that takes two mono bitmaps.

    add .make.cache files to .gitignore

    Correct implementation of QApplication::setOverrideCursor

    QApplication::restoreOverrideCursor and QApplication::setOverrideCursor
    are now working correctly on Symbian platform.
    Performance will be slower compared with other platforms, because the
    Symbian window server has a cursor associated with each native window.

    Add test case for custom cursors

    Create a pixmap cursor and associate it with a widget.
    No changes to production code, since test passed 1st time ;)

    Add manual test for QCursor

    Make cursor independent of construction order

    Updated to work around window server issue where contruction order
    affects what cursor is displayed in child windows.
    Also changed to effectiveWinId following review comments
    Also fixed a problem which would make qcursor not link if configured
    with QT_NO_CURSOR

    Moved some multiply declared extern functions from cpp to _p.h files
    Implemented Symbian versions of the cursor functions.

    Merged in work I'd done based on tower.
    Fill in bits of stub functions based on windows port

    Removed QT_NO_CURSOR from list of config options forced on symbian
    Recompiled configure.exe
    Added stub functions for the missing functions in s60 port
