Skip drawing the frame when using the null driver - some GL implementations
crash otherwise

Change default serial output to /dev/tty rather than /dev/console
src/drivers/serial_unix.c

Fix SCIF operation
- status updates weren't being written back to the register (oops)
- slice cycle not updated on partial tick execution
- baudrate computation was always 0
src/sh4/scif.c

Create a host attachment for the SCIF serial port. By default, uses /dev/console
Add general fd listening to netutil, and rename to ioutil
Add SCIF update on port read/write - fixes KOS timing problems but needs to
be redone properly.

Rearrange frame output slightly.
pvr2_display_frame renamed to pvr2_next_frame and changed to update the
frame data without displaying it.
pvr2_redraw_display renamed to pvr2_draw_frame, called internally after
pvr2_next_frame
Add swap_buffers() method to the display driver
Remove explicit glDrawBuffer() calls where they're referencing the window.
pvr2_draw_frame now gets to decide where to draw.
Add force_vsync flag to force double-buffering (not configurable yet)

Fix more -Wall issues
- Configure was failing to check -rdynamic properly with --enable-strict-warn turned on
- Minor 64-bit cleanliness problems

Update ALSA driver to the new config regime
src/drivers/audio_alsa.c

Heavy configuration management refactor
- Configuration groups now take both an on_change event handler and a
default keybinding handler, making most keybinding tasks quite simple
- GUI configuration all merged into a unified model, drastically reducing
the amount of GUI config code.

Bonuses
- OSX now has a hotkey preference pane
- GTK keybinding editor is much more usable
