Emmanuele Bassi 54cc43630d Rename the generated private data getter function 
As it turns out, we have examples of internal functions called
type_name_get_private() in the wild (especially among older libraries),
so we need to use a name for the per-instance private data getter
function that hopefully won't conflict with anything.

/**
* SECTION:gmountoperation
* @short_description: Object used for authentication and user interaction
* @include: gio/gio.h
*
* #GMountOperation provides a mechanism for interacting with the user.
* It can be used for authenticating mountable operations, such as loop
* mounting files, hard drive partitions or server locations. It can
* also be used to ask the user questions or show a list of applications
* preventing unmount or eject operations from completing.
*
* Note that #GMountOperation is used for more than just #GMount
* objects – for example it is also used in g_drive_start() and
* g_drive_stop().
*
* Users should instantiate a subclass of this that implements all the
* various callbacks to show the required dialogs, such as
* #GtkMountOperation. If no user interaction is desired (for example
* when automounting filesystems at login time), usually %NULL can be
* passed, see each method taking a #GMountOperation for details.
