Introduce g_volume_monitor_adopt_orphan_mount() function. Also add signals

2007-12-19  David Zeuthen  <davidz@redhat.com>

	Introduce g_volume_monitor_adopt_orphan_mount() function. Also
	add signals 'disconnected' and 'eject-button' on GDrive. Add
	signal 'removed' on GVolume and 'unmounted' on GMount.

* This function should be called by any #GVolumeMonitor

* associated with a #GVolume object. It must be called just before
* emitting the @mount_added signal.
*
* If the return value is not %NULL, the caller must associate the
* returned #GVolume object with the #GMount. This involves returning
* it in it's g_mount_get_volume() implementation. The caller must
* also listen for the "removed" signal on the returned object
* and give up it's reference when handling that signal
*
* Similary, if implementing g_volume_monitor_adopt_orphan_mount(),
* the implementor must take a reference to @mount and return it in
* it's g_volume_get_mount() implemented. Also, the implementor must
* listen for the "unmounted" signal on @mount and give up it's
* reference upon handling that signal.
*
* There are two main use cases for this function.
*
* One is when implementing a user space file system driver that reads
* blocks of a block device that is already represented by the native
* volume monitor (for example a CD Audio file system driver). Such
* a driver will generate it's own #GMount object that needs to be
* assoicated with the #GVolume object that represents the volume.
*
* The other is for implementing a #GVolumeMonitor whose sole purpose
* is to return #GVolume objects representing entries in the users
* "favorite servers" list or similar.
*
* Returns: the #GVolume object that is the parent for @mount or %NULL
* if no wants to adopt the #GMount.
