devvga: properly handle physical screen size and panning

- remove arbitrary limits on screen size, just check with badrect()
- post resize when physgscreenr is changed (actualsize ctl command)
- preserve physgscreenr across softscreen flag toggle
- honor panning flag on resize
- fix nil dereference in panning ctl command when scr->gscreen == nil
- use clipr when drawing vga plan 9 console (vgascreenwin())
