5d11489d74 Make printk() log to a buffer.
Tested on Qemu and Geode LX.
Benefits of this patch:
- printk() now works directly after printk_buffer_init(), even before
the serial port is set up.
- If all you want is a log, you don't have to bother with serial output.
- A payload can read and analyze the log.
- You can build on this and buffer log until serial is available, then
flush the messages buffered so far.

The printk buffer is configurable with a default-on Kconfig variable.

If you want to dump the buffer from the Qemu monitor after CAR has been
disabled, use this command:
memsave 0x90000 65536 memdump.bin

e28f0155f6 Only post_code.h should have the prototype for post_code() from
post_code.c (thus drop it from console.h).

Instead, have console.h #include post_code.h and drop other
explicit #includes of post_code.h in the code; console.h is already
included in pretty much every file.

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.
