For x86 the files that become the BIOS blob are compiled with -m32.
Although we avoid including any system libraries, we use some headers
from /usr/include, which asks for trouble if compiling on a x86-64
multiarch system (Debian/Ubuntu). Without 32-bit compat headers
installed there, the compiler will not find the right files.
However as the BIOS code is actually a self-contained binary without
any relationship to the Linux userland, it should not use or rely
on Linux system headers.
Replace includes of linux/types.h in BIOS code with asm/bios/types.h,
which simply contains the u{8,16,32,64} data types needed by the code.

Tidy up the code in hw/vesa.c:
- Make videomem local to hw/vesa.c
- Remove debugging printf() calls
- Fix up coding style issues

Add a simple VESA device which simply moves a framebuffer
from guest kernel to a VNC server.
VESA device PCI code is very similar to virtio-* PCI code.
