Doc: Remove docs for old, deleted, platform-specific functions

Most of these functions were removed prior to the release of Qt 5.0.
Three of them remain in the code base though:

1. qt_set_sequence_auto_mnemonic()
2. qt_mac_set_dock_menu()
3. qt_mac_secure_keyboard()

(1) is currently referenced by the QShortcut class ref, so I'm
transferring its documentation to QKeySequence.

(2) is already documented under QMenu.

(3) is not mentioned anywhere else in the Qt docs, so I'll just leave it
undocumented and let it be quietly replaced with a better function.

-    \page exportedfunctions.html
-    \title Platform-Specific Functions
-    \ingroup funclists
-
-    \brief Exported functions for fine tuning Qt applications.
-
-    Qt provides a few low-level global functions for fine-tuning
-    applications. Most of these perform very specific tasks and are
-    platform-specific. In general, we recommend that you try using
-    Qt's public API before resorting to using any functions mentioned
-    here.
-
-    These functions are exported by \l QtCore and \l QtGui, but most
-    of them aren't declared in Qt's header files. To use them in your
-    application, you must declare them before calling them. For
-    example:
-
-    \snippet snippets/code/doc_src_exportedfunctions.qdoc 0
-
-    These functions will remain as part of Qt for the lifetime of Qt
-    4.
-
-    Functions:
-
-    \tableofcontents
-
-    \section1 void qt_set_library_config_file(const QString &\e{fileName})
-
-    Specifies the location of the Qt configuration file. You must
-    call this function before constructing a QApplication or
-    QCoreApplication object. If no location is specified, Qt
-    automatically finds an appropriate location.
-
-    \section1 void qt_set_sequence_auto_mnemonic(bool \e{enable})
-
-    Specifies whether mnemonics for menu items, labels, etc., should
-    be honored or not. On Windows and X11, this feature is
-    on by default; on OS X, it is off. When this feature is off,
-    the QKeySequence::mnemonic() function always returns an empty
-    string. This feature is also enabled on embedded Linux.
-
-    \section1 void qt_x11_wait_for_window_manager(QWidget *\e{widget})
-
-    Blocks until the X11 window manager has shown the widget after a
-    call to QWidget::show().
-
-    \section1 void qt_mac_secure_keyboard(bool \e{enable})
-
-    Turns the OS X secure keyboard feature on or off. QLineEdit
-    uses this when the echo mode is QLineEdit::Password or
-    QLineEdit::NoEcho to guard the editor against keyboard sniffing.
-    If you implement your own password editor, you might want to turn
-    on this feature in your editor's
-    \l{QWidget::focusInEvent()}{focusInEvent()} and turn it off in
-    \l{QWidget::focusOutEvent()}{focusOutEvent()}.
-
-    \section1 void qt_mac_set_dock_menu(QMenu *\e{menu})
-
-    Sets the menu to display in the OS X Dock for the
-    application. This menu is shown when the user attempts a
-    press-and-hold operation on the application's dock icon or
-    \key{Ctrl}-clicks on it while the application is running.
-
-    The menu will be turned into a Mac menu and the items added to the default
-    Dock menu. There is no merging of the Qt menu items with the items that are
-    in the Dock menu (i.e., it is not recommended to include actions that
-    duplicate functionality of items already in the Dock menu).
-
-    \section1 void qt_mac_set_menubar_icons(bool \e{enable})
-
-    Specifies whether icons associated to menu items for the
-    application's menu bar should be shown on OS X. By default,
-    icons are shown on OS X just like on the other platforms.
-
-    In Qt 4.4, this is equivalent to
-    \c { QApplication::instance()->setAttribute(Qt::AA_DontShowIconsInMenus); }.
-
-    \section1 void qt_mac_set_menubar_merge(bool \e{enable})
-
-    Specifies whether Qt should attempt to relocate standard menu
-    items (such as \gui Quit, \gui Preferences, and \gui About) to
-    the application menu on OS X. This feature is on by default.
-    See \l{Qt for OS X - Specific Issues} for the list of menu items for
-    which this applies.
-
-    \section1 void qt_mac_set_native_menubar(bool \e{enable})
-
-    Specifies whether the application should use the native menu bar
-    on OS X or be part of the main window. This feature is on by
-    default.
-
-    In Qt 4.6, this is equivalent to
-    \c { QApplication::instance()->setAttribute(Qt::AA_DontUseNativeMenuBar); }.
-
-    \section1 void qt_mac_set_press_and_hold_context(bool \e{enable})
-
-    Turns emulation of the right mouse button by clicking and holding
-    the left mouse button on or off. This feature is off by default.
