at the same time simplify the #includes and their hierarchies.

The LB_TAG_COMPILE_TIME is a partly duplicate of LB_TAG_BUILD,
as LB_TAG_BUILD contains both date and time. I left this in for
compatibility reasons.

Add "(LB) " to all log messages to differentiate them visually
from the rest of the boot messages. This is similar to what
Xen does when booting (it prefixes all log messages with "(XEN) ").

Comitting IP checksum code, and its usage in linuxbios table creation.
Mods to the dts, so that the device ops for the domain are set to the
proper structure. This change is important. It gets rid of the obscure,
confusing use of the enable_dev function to pick the right ops for a
device. It makes the ops initilization very clear at the top level, in
the dts. This has been tested and works, linux boots on Bochs under
this version.

add debug printks.
make dtc put 'root' as the first_node, instead of making the last node
be the first node .... much happier in linuxbios.
sprintf is broken ... dammit. I hope someone will fix it. I've got about
another week of full-time I can spend on this and then I go back to part
time. So I'm going to need some help soon.
other fixups, and also, make the dts conform to the needs of the device
tree. So we have a domain0 and a device (0,0) that is the north.
Mostly things are working, but we're STILL not getting any memory in the
LB tables from the north. The device tree is a bitch.

Remaining to be done:
PIRQ table
MP table
ACPI table
relocate the GDT reload to a sensible place -- or figure out if we even
need to bother; we're back to execute in place and the GDT is in flash
rom ==> we can leave it until we boot the payload I think.
At this point, however, we've got the basic bits to sensibly create
tables.
This has been tested and works on bochs.
It is working to a point, but still failing on qemu for reasons we don't
quite understand.

resource .c functions -- sigh -- this will be next.
fix types, fix some usage, but we do not yet generate pirqi, mptables,
or acpi. This will be next.
This code will be called from phase6 in stage 2, and probably
attached to a cpu. Or, it will be inline in the stage2.c code, since
the need for tables is generic.
I'm also going to move the cryptic usage of lgdt from here to stage 2,
phase 2, of the cpu code. The device model improvements are making it
easier to think about when things happen, we are finding.
I'm going to get lunch and go see some of brussels. It's a miserable day
but ...

We have merged the plethora of include files into one. A given linuxbios
target architecture must support all the functions described therein.
All the structs etc. in include/tables.h are known to be
architecture-independent.
We hope this new layout is easier to folow than the old one.
Todo: Remove the LGDT code from tables writing (how did THAT get in
there ;-) and put it somewhere sane; add OFW table support. We are going
to need some nice OFW table code.
Also, the license headers should be correct in this commit.
