Log Message:
Update to 2.4.3.  While here, rework the way the libdata/ files are handled
by creating/deleting them from the (de)install scripts (and not registered
in the PLIST).  This allows pkg_tarup to work properly and also avoids some
warnings during 'make replace'.

Changes since 2.4.2:
* GtkButton
 - Give extra space to children of !CAN_FOCUS buttons [Matthias Clasen]
* GtkFileChooser
 - Make DND work when the dialog is modal [Federico Mena Quintero]
* GtkToolbar
 - Don't show empty overflow menu [Soeren Sandmann]
 - Don't show initial separator in overflow menu [Soeren]
 - Handle dynamic changes to overflow menu [Soeren]
* Documentation improvements [Bastien Nocera, Matthias]
* Other bug fixes [Matthias, Soeren, Sven Neumann]
* Updated translations (hu,ne)
