* Fixed mixup of the VGA compatibility layer - if the bit is set, it means the
device is not compatible, after all.
* No longer accept color changes if the mode is not an 8 bit one. I think that
BWindowScreen does that after changing the mode, so that is messes up the
colors, at least that's the theory, will test on real iron now.
* Use VGA as a fallback if setting the palette via VBE failed. This brings back
the colors for ParticlesII in Qemu (but not in VirtualBox, which seems to be
completely broken in this regard).

* Added VESA capabilities field to the kernel args.
* The vesa driver no longer uses VGA programming if the chip does not support
VGA compatibility.
* The VESA driver now tries to set the DAC to 8 bits per color gun.
* In VESA modes, the driver no longer tries to use VGA programming; introduced
the new vesa_set_indexed_colors() that is now used for palette programming.
This should fix wrong colors of 8 bit BWindowScreen users with VESA on real
hardware (emulators usually didn't mind either way).
* Note that the app_server needs to maintain a palette per 8 bit screen, as
right now, the colors are garbled after a workspace switch. Stefano, are you
looking into that already?

* This fixes VGA mode frame buffer use, no idea when this got broken. It might
be broken in the app_server now, but I haven't checked yet.
* Fixed typo in vesa.h.

* Added DPMS support to the VESA driver, in case the hardware/BIOS supports it.
* Minor cleanup.

* The boot loader now creates a CRTCInfoBlock structure when detailed EDID
mode informations are available.
* This is passed to the graphics card when the mode is set in the hopes that it
will be more conforming.
* Not yet tested on real hardware, though, therefore the VESA driver doesn't
do anything like this yet. I will test next, but please report any problems
with this nonetheless.

Moved the vesa.h and vga.h headers to the private vesa driver header directory
for future use.
