- no need to call the colourdepth callback in text mode: the buffer
cannot be shared anyway;
- line size changes are currently undetected: since we added a
linesize parameter to the resize callback, we also need to detect
line size changes and call dpy_resize accordingly;
- 8 bit colour depth with the shared framebuffer is broken: in order
to fix it I disabled the shared buffer in vnc for the 8bit colour
depth case (it has to be done in software anyway..) and implemented
paletted colours in both opengl and sdl;
- opengl rendering is broken when there is padding in the framebuffer
lines: removing unnecessary GL_UNPACK_ALIGNMENT settings so that the
GL_UNPACK_ROW_LENGTH parameter can work properly.
hvmloader: Properly implement some more SMBIOS fields.
In particular:
- BIOS release date
- BIOS characteristics
- BIOS extended characteristics (Targeted Content Distribution is
required to be specified to pass WHQL).

The latest -mm kernel (2.6.25-rc3-mm1) contains v2.08 of the Linux
bzImage format which embeds an ELF file in place of the raw payload
allowing it to be extracted and used by the Xen domain builder.
It is expected that this functionality will be put forward for 2.6.26.

Revert all usages of gcc's __extension__ keyword, and instead assert

__extension__ had some weird (and buggy) behaviours when nested which

files. Better to disallow -ansi, -std=c99, and similar gcc options
