David Zeuthen 99a1c47343 Allow interaction when unmounting mounts
For details, see bug 587482. The new api:

 - Provide new _with_operation() variants of all unmount and eject methods

 - Add GMountOperation::show-processes signal
   - this can be used to show processes blocking an unmount operation

 - Deprecate all unmount and eject methods

 - Add g_drive_can_start_degraded() method
   - this is to avoid auto-starting degraded drives

 - Make g_drive_stop() resp. g_file_stop_mountable() take a GMountOperation
   - these ops were recently added and not yet public API so it's fine
     to change how they work

 - Provide a way to poll mountable files, e.g. g_file_poll_mountable()

 - Add some missing file attributes for mountable files
  - G_FILE_ATTRIBUTE_MOUNTABLE_UNIX_DEVICE_FILE
    - needed for the GDU Nautilus extensions to format a volume
  - G_FILE_ATTRIBUTE_MOUNTABLE_CAN_START_DEGRADED:
    - mimics g_drive_can_start_degraded()
  - G_FILE_ATTRIBUTE_MOUNTABLE_CAN_POLL:
    - mimics g_drive_can_poll_for_media()
  - G_FILE_ATTRIBUTE_MOUNTABLE_IS_MEDIA_CHECK_AUTOMATIC
    - mimics g_drive_is_media_check_automatic()

* @eject_button: Signal emitted when the physical eject button (if any) of a drive have been pressed.
* @get_name: Returns the name for the given #GDrive.
* @get_icon: Returns a #GIcon for the given #GDrive.
* @has_volumes: Returns %TRUE if the #GDrive has mountable volumes.
* @get_volumes: Returns a list #GList of #GVolume for the #GDrive.
* @is_media_removable: Returns %TRUE if the #GDrive supports removal and insertion of media.
* @has_media: Returns %TRUE if the #GDrive has media inserted.
* @is_media_check_automatic: Returns %TRUE if the #GDrive is capabable of automatically detecting media changes.
* @can_poll_for_media: Returns %TRUE if the #GDrive is capable of manually polling for media change.
* @can_eject: Returns %TRUE if the #GDrive can eject media.
* @eject: Ejects a #GDrive.
* @eject_finish: Finishes an eject operation.
* @poll_for_media: Poll for media insertion/removal on a #GDrive.
* @poll_for_media_finish: Finishes a media poll operation.
* @get_identifier: Returns the identifier of the given kind, or %NULL if
* the #GDrive doesn't have one.
* @enumerate_identifiers: Returns an array strings listing the kinds
* of identifiers which the #GDrive has.
* @get_start_stop_type: Gets a #GDriveStartStopType with details about starting/stopping the drive. Since 2.22.
* @can_stop: Returns %TRUE if a #GDrive can be stopped. Since 2.22.
* @stop: Stops a #GDrive. Since 2.22.
* @stop_finish: Finishes a stop operation. Since 2.22.
* @can_start: Returns %TRUE if a #GDrive can be started. Since 2.22.
* @can_start_degraded: Returns %TRUE if a #GDrive can be started degraded. Since 2.22.
* @start: Starts a #GDrive. Since 2.22.
* @start_finish: Finishes a start operation. Since 2.22.
* @stop_button: Signal emitted when the physical stop button (if any) of a drive have been pressed. Since 2.22.
* @eject_with_operation: Starts ejecting a #GDrive using a #GMountOperation. Since 2.22.
* @eject_with_operation_finish: Finishes an eject operation using a #GMountOperation. Since 2.22.
