ubb-vga: express mode data in more common units and remove hard-coded constants

Browse Source 
- ubb-vga.h (struct mode), ubb-vga.c (mode_db): replaced hsync_end with
  its constituends hsync_cycles and hback_cycles
- ubb-vga.h (struct mode), ubb-vga.c (mode_db): added vsync_lines,
  vfront_lines, and vback_lines
- ubb-vga.h (struct mode): changed "line_cycles" from "int" to
  "uint16_t"
- ubb-vga.c (line): don't hard-code horizontal back porch
- ubb-vga.c (line): don't hard-code sum of horizontal back porch and
  hsync
- ubb-vga.c (hdelay): don't hard-code hsync
- ubb-vga.c (frame): don't hard-code vsync and the vertical porches
