[PXE] Add PMM support to romprefix.S (untested)
...
ROM initialisation vector now attempts to allocate a 2MB block using
PMM. If successful, it copies the ROM image to this block, then
shrinks the ROM image to allow for more option ROMs. If unsuccessful,
it leaves the ROM as-is.
ROM BEV now attempts to return to the BIOS, resorting to INT 18 only
if the BIOS stack has been corrupted.

Remove the (unused) option to override _prefix_link_addr,
...
_textdata_link_addr, _load_addr and _max_align in the linker scripts.
A bug in some versions of ld causes segfaults if the DEFINED() macro
is used in a linker script *and* the -Map option to ld is present.
We don't currently need to override any of these values; if we need to
do so in future then the solution will probably be to always specify
the values on the ld command line, and have the linker script not
define them at all.

Update all prefixes currently referring to _load_size to include a

compressor fixup section.

Rename _rom_size to _load_size_sect, since hdprefix.S also uses it.

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).

Towards making KEEP_IT_REAL work again.
...
Fix bug that caused over-allocation of .text16 and .data16 memory areas
by a factor of 16.

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

ISA bus driver updated to report devices as present only if a driver

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.
