Directory structure for x86emu

[Li-Ta Lo]

Hello,

It turns out that the VGABIOS support can be made pretty generic
for all kinds of PCI expansion ROM. So I have the emulator the
.init method of default_pci_ops_dev. I am going to add the following
directories, if there is no objection, I will commit it next week.

src/include/x86emu -- public header file of x86emu
src/devices/pci_rom.c -- expansion ROM loading and execution
src/devices/emulator -- the emulator and supporting functions
src/devices/emulator/x86emu -- the emulator itself
src/devices/emulator/pcbios -- legacy PC BIOS handler for the emulator
src/devices/emulator/biosemu.c -- glue between pci_rom.c and the 				 
emulator

Any comments ?
