Use a single _payload_offset linker-defined variable to locate the
...
start of the non-prefix blocks in the loaded image, and rely on the
image ordering. This should make introducing compression much easier.

image file.

Prevent NULL from ever pointing to some real code or data. (This was
...
causing the serial console to ignore input, because it happened to end up
linked with serial_ischar() at address 0, which core/console.c decided was
invalid).

Added null trap code for debugging. (Must be included by adding
...
--nulltrap to the make target at the moment.)

Create two easy-to-use entry points in libprefix: install and
...
install_prealloc. I *think* these will suffice for all the 16-bit
prefixes.

Towards a(nother) new real-mode infrastructure, in which we take

advantage of the fact that we have to have a permanently-resident block
in base memory.

ISA bus driver updated to report devices as present only if a driver
...
thinks they are.
Other bus drivers modified for consistency.

Created a bus/device API that allows for the ROM prefix to specify an
...
initial device, and will also allow for e.g. a device menu to be presented
to the user.
