Use {get,set}_fbms() so that allocated base memory is correctly hidden.

Provide {get,set}_fbms() in basemem.h.

set_fbms() will also update the E820 hidden region.

Some operating systems get a nasty shock if a region of the E820 map seems

to start on a non-page boundary. Make life safer by rounding out our
edited regions.

I prefer IMAGE_XXX to XXX_IMAGE.

Add IMAGE_PXE to use the new image format framework. "kernel pxelinux.0"
now works.

Always send EOI. We can't feasibly share interrupts (since we have no
...
clue what the "previous" interrupt handler will do, which could range
from "just an iret" to "disable the interrupt"), and that means that
we have to take responsibility for ACKing all interrupts. Joy.

Provide registration mechanism for loaded images, so that we can e.g.

refer to them by name from the command line, or build them into a
multiboot module list.
Use setting image->type to disambiguate between "not my image" and "bad
image"; this avoids relying on specific values of the error code.
