vga: fix text mode updating
With both text (curses) and graphics (vnc/sdl/spice/...) display active vga text mode emulation fails to update both correctly. Depending on whenever vga_update_text() or vga_draw_text() happens to be called first only the text display or only the graphics display will see display resolution changes and full redraws. Fix it by calling both text/gfx resize functions in both code paths and keep track of full screen redraws needed in VGACommonState fields. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
