-stable review patch. If anyone has any objections, please let us know.

From: Samuel Thibault <samuel.thibault@xxxxxxxxxxxx>
VT notifier callbacks need to be aware of console switches. This is already
partially done from console_callback(), but at that time fg_console, cursor
positions, etc. are not yet updated and hence screen readers fetch the old
values.
This adds an update notify after all of the values are updated in
redraw_screen(vc, 1).
