Make use the existing GDT which now includes entries for 64-bit code.
Leave the interrupt descriptors alone. They can be tidied up once U-Boot
starts up.
With this, kvm mode works with QEMU.

Any 'bootable' flag in a DOS partition causes boostd to only scan
bootable partitions for that media. This can mean that extlinux.conf
files on the root disk are missed.
Put this logic behind a flag and update the documentation.
For now, the flag is enabled, to preserve existing behaviour. Future

With the 64-bit descriptor we can use a jump instruction, rather than
pushing things on the stack.
Since the processor is in 64-bit mode by this point, pop a 64-bit value
from the stack, containing the target address.
This simplifies the code slightly, in particular its use of the stack.

BSS is placed in DRAM which is actually available early with QEMU. But
it is cleared by the init sequence, so values stored there are lost.

The vesa display is widely used on hardware, but it is a bit of a pain
with QEMU. It requires executing option ROMs, which either doesn't work
with kvm, or is difficult to do in a kvm/QEMU-friendly way.
THe bochs display is probably better anyway, so switch to that. It works
fine with kvm as it do
U-Boot clears the display when it starts up, so there is no need to ask
the VESA driver to do this. Fix this and add a comment explaining the
flags.

The existing QEMU implementation mostly ignored BLOBLIST_TABLES and
