e5fcf247f2 gcc -fwhole-program needs to mark any function which is used outside the
current compilation unit to be marked as externally_visible. We have
EXPORT_SYMBOL exactly for that purpose.

This applies to the following symbols used by x86emu and/or vm86:
- pci_read_config8
- pci_read_config16
- pci_read_config32
- pci_write_config8
- pci_write_config16
- pci_write_config32
- dev_find_pci_device
- dev_find_slot
It also applies to the main entry point of stage2:
- stage2

With this patch, I can use -fwhole-program for stage2 without any
problems. For standard compilation, this is a noop.

9342d1be4e The ABI wrapper from r775 made the SHARED definitions obsolete. They're
not that readable anyway, so kill them and use standard definitions
instead.

Introduce EXPORT_SYMBOL for shared symbols. EXPORT_SYMBOL tells the
compiler to use the standard calling conventions for a given symbol and
not to optimize it away.
Benefits:
- We can later use gcc -combine -fwhole-program without problems.
- It's a correctness fix for some optimizations.
- We could check for duplicated exported functions at link time.
- We could check whether exported functions are linked into initram or
stage2 by accident.
- We could generate usage statistics and possibly optimize away unused
shared functions.
- Through the above points, significant side reductions of 10-40%

Build and boot tested on qemu.
Build tested on all targets.

6a732582c7 Here we start to see the good design of 3. In v2, there were pci ops in
all stages, blighting everything with the same code, compiled different 
ways. In this change, we see that:
- basic conf ops are compiled into stage0, where they are used. 
- they are called directly from initram
- they are used to initialize the pci_cf8_conf1 structure in stage 2, 
   but the call still goes to stage0!

one copy of the code.

464ef4613d Use the same naming convention and placement for "include guards" in
all header files.

This closes #40, as I think we don't need to invest time to fix this in
LinuxBIOSv2, but only in LinuxBIOSv3.

71ccb36afc Massive file rename and moving orgy:
- Everything in include/cpu/generic/x86/arch/* goes into
   include/arch/x86 now.

 - include/cpu/generic/x86/div64.h moves into include/arch/x86, too.

 - The former include/cpu/generic/x86/arch/elf.h moved to
   include/arch/x86/archelf.h, as elf.h already exists in include/
   and we must prevent a name clash.
