printk buffer management to it.
Build tested and boot tested and result tested on Qemu.
Adding a new global variable is not as easy as it looks, but the
comments in the code should be good enough to tell you how.

(1)we now compile in all printks, which is good: we can print any message provided we can change
the console log level at any time.
(2) The console log level is compiled in and unchangeable, which is bad, as it defeats the purpose of (1).
Add a BIOS_ALWAYS log level. Make console log level a variable. Make functions that set it and get it
visible everywhere. Always print out the version message; this is really *not* noise!
PCI: Simplify pci functions so that they can be used in stage1 or anywhere for that matter. Add
a find function which is needed for many stage1 functions. Note that we copy but also clean up
the libpayload stuff just a bit.
Get rid of config space type 2. If there was ever a platform that used it, I don't know what it was,
and the presence is a needless distraction.
tested and working on DBE62 (which means the console and the pci functions work :-).
There is a remaining problem with dumplxmsrs which nobody understands. It prints out garbage if we use the
%s for the msr names.
Formatting is an issue; if somebody wants to fix formatting they can assume I will ack it. Sorry,
my emacs has gone just nuts.

CONFIG_* == 1. If those variables are set, they will always be 1.

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

- I left LB_TAG_ intact because they are used by the payloads
- file renames are still missing. see next commit
- some lb_ renames might be missing. feel free to provide patches.

* make constructor an initializer.
* fix memory leak/code flow error in current code
* add spinlocking
* drop malloc and use new_device for device allocation instead.
* add CONFIG_SMP as it is needed by spinlocks and soon other stuff.

- lib/console.c: BIOS_SPEW never kicked in.
- util/xcompile/xcompile: the "function" prefix isn't supported by all shells.
