These changes implement car in qemu. The implementation is in several

ways superior to v3, while lacking its completeness. But, one nice 
thing: no more included .S or .c files. It's all separate compilation. 
That should allow our Makefiles to work much better.

Note that the current non-CAR implementation is the default and 
continues to work (tested FILO boot to Linux on both CAR and non-CAR).

Change this to be sensitive to USE_DCACHE_RAM. All settings etc. that 
depend on this variable are grouped in one if, and the other parts 
(romcc etc.) are in the else. This change is a model of how we should be 
able to do other motherboards.

Index: src/mainboard/emulation/qemu-x86/Options.lb
add needed options. 

Index: src/mainboard/emulation/qemu-x86/failover.c
remove code inclusion from this not-yet-used file. 

Index: src/mainboard/emulation/qemu-x86/rom.c
This is the entry point for the rom-based code. Called stage1.c in v3. 

Index: src/lib/Config.lb
change initobject to a .o from a .c; this fixed a build problem. 

Index: src/pc80/serial.c
make uart_init non-static. 

Index: src/pc80/Config.lb
add initobject

Index: src/arch/i386/init/entry.S
Entry point. Unify a bunch of files that were fiddly lttle includes. From v3. 

Index: src/arch/i386/init/ldscript.ld
new file. The goal is to hang all init changes for CAR here, to minimize other changes to any
other ldscript. Besides, putting this in init makes sense; entry and car are manage init. 

Index: src/arch/i386/init/car.S
generic i386 car code from v3. 

Index: src/arch/i386/init/ldscript_fallback_cbfs.lb
Fix what looks like a bug: this was not including the init.text section. 

Index: targets/emulation/qemu-x86/Config.lb
push up the console loglevel. qemu is for debugging so we might as well 
get all the debugging we can. 

Index: targets/emulation/qemu-x86/Config-car.lb
For CAR bullds.
