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()

/**
* GMountIface:
* @g_iface: The parent interface.
* @changed: Changed signal that is emitted when the mount's state has changed.
* @unmounted: The unmounted signal that is emitted when the #GMount have been unmounted. If the recipient is holding references to the object they should release them so the object can be finalized.
* @pre_unmount: The pre_unmout signal that is emitted when the #GMount will soon be emitted. If the recipient is somehow holding the mount open by keeping an open file on it it should close the file.
* @get_root: Gets a #GFile to the root directory of the #GMount.
* @get_name: Gets a string containing the name of the #GMount.
* @get_icon: Gets a #GIcon for the #GMount.
* @get_uuid: Gets the UUID for the #GMount. The reference is typically based on the file system UUID for the mount in question and should be considered an opaque string. Returns %NULL if there is no UUID available.
* @get_volume: Gets a #GVolume the mount is located on. Returns %NULL if the #GMount is not associated with a #GVolume.
* @get_drive: Gets a #GDrive the volume of the mount is located on. Returns %NULL if the #GMount is not associated with a #GDrive or a #GVolume. This is convenience method for getting the #GVolume and using that to get the #GDrive.
* @can_unmount: Checks if a #GMount can be unmounted.
* @can_eject: Checks if a #GMount can be ejected.
* @unmount: Starts unmounting a #GMount.
* @unmount_finish: Finishes an unmounting operation.
* @eject: Starts ejecting a #GMount.
* @eject_finish: Finishes an eject operation.
* @remount: Starts remounting a #GMount.
* @remount_finish: Finishes a remounting operation.
* @guess_content_type: Starts guessing the type of the content of a #GMount.
* See g_mount_guess_content_type() for more information on content
* type guessing. This operation was added in 2.18.
* @guess_content_type_finish: Finishes a contenet type guessing operation. Added in 2.18.
* @guess_content_type_sync: Synchronous variant of @guess_content_type. Added in 2.18
* @unmount_with_operation: Starts unmounting a #GMount using a #GMountOperation. Since 2.22.
* @unmount_with_operation_finish: Finishes an unmounting operation using a #GMountOperation. Since 2.22.
* @eject_with_operation: Starts ejecting a #GMount using a #GMountOperation. Since 2.22.
* @eject_with_operation_finish: Finishes an eject operation using a #GMountOperation. Since 2.22.
*
* Interface for implementing operations for mounts.
