Gets the stage0 bootstrap to run.
Imlementation is probably nonsense at this point.

There have been multiple reports that these changes break mounting NTFS partitions
(on all systems, see #14204), and shutting down (on certain systems, see #12405.)
Until they can be fixed, they are being backed out.
* also adjust BOOT_GDT_SEGMENT_COUNT for x86, the definition is used by the
boot loader.
* add some 32-bit definitions.
* add a UserTLSDescriptor class, this will be used by 32-bit threads.

SMAP will generated page faults when the kernel tries to access user pages unless overriden.
If SMAP is enabled, the override instructions are written where needed in memory with
binary "altcodepatches".
Support is enabled by default, might be disabled per safemode setting.

* Eventually BoardSetups and target boards will go away.
* Include all known fdt's in the mmc image
* This gets us closer to target board-less arm
* Changing hardware is as simple as plugging a new fdt
into u-boot's startup script.
* Drop my original rpi1 work. We're targetting ARMv7
minimum.
* beaglebone vs beagleboard
* While the boards are almost the same, they have
diff. FDT's now (more memory, different layout etc)
* Make u-boot script more rpi-like
(depend on u-boot for initial addresses)
* Wasn't working, still doesn't.
Similar to arch_get_debug_cpu_state(), but the thread whose CPU state
to retrieve is specified. Works only for threads that aren't running,
and on x86-64 we can get the FPU state only when the thread was
interrupted in userland.
Not implemented for the incomplete architecture ports.
* New Intel SkyLake seems to have 9 mapped ranges
at boot. It seems like this define has been creeping
up for a while.
* Resolves the inital issue reported in #11377 on SkyLake
as well. Bonefish mentioned it might need to be raised
again... he had some good foresight there :-)
* I'm seeing the same no bootable partitions issue though
via USB after this raise. (maybe a USB 3.1 thing?)
Reduce duplication of code by
* Removing from elf_common.h definitions available in os/kernel/elf.h
* Deleting elf32.h and elf64.h
* Renaming elf_common.h to elf_private.h
* Updating source to build using public and private ELF header files
together

* Called via arm_mailbox_bcm2835 *and* arm_framebuffer_bcm2835
* This is a bit messy. We really should be getting these
chipset-centric bases from the provided FDT / DTB.
* I can't think of a way to redo this without undoing
work towards FDT.
* The Raspberry pi 2 uses a new SoC which differs slightly
from the Raspberry Pi 1.
* Someday these two board targets could go away when we get
FDT support.
* To while there was some compatibility between
BCM2708 and BCM2805, it makes the BCM2806 changes
more confusing. We don't have any valueable BCM2708
targets.
