623f3ccbe3 ubb-vga2: non-contiguous allocation of frame buffer memory 
- ubb-vga.h (calloc_phys_vec), physmem.c: non-contiguous memory allocator
  (for now, without really considering any mapping to physical memory)
- Makefile (OBJS): added physmem.o
- ubb-vga.h (grabfb), grabfb.c (grabfb): API change for non-contiguous
  frame buffer
- ubb-vga.h (ppmimg), ppmimg.c (convert, ppmimg): API change for
  non-contiguous frame buffer
- ubb-vga.h (tstimg), tstimg.c (pixel, color_bars, grill, grid, sides,
  dot, line45, arc, printc, text, ctext, tstimg): API change for
  non-contiguous frame buffer
- tstimg.c (tstimg): we no longer need to clear the frame buffer
- ubb-vga.c (frame, session, main): use a vector of line buffers instead
  of a contiguous frame buffer
