[prefix] Add PCI bus:dev.fn to ROM product string
...
This allows multiple gPXE ROMs in a system to be disambiguated at boot
time; the PCI ID will show up in the boot menu for a BBS-compliant BIOS.

[PXE] Improve PnP/BBS detection
...
Use BBS installation check to see if we need to hook INT19 even on a PnP
BIOS.
Verify that $PnP signature is paragraph-aligned; bochs/qemu BIOS provides
a dummy $PnP signature with no valid entry point, and deliberately
unaligns the signature to indicate that it is not properly valid.
Print message if INT19 is hooked.
Attempt to use PMM even if BBS check failed.

[prefix] Add printing functions to libprefix.S
...
Move the printing functions from pxeprefix.S into libprefix.S, so they
are available for debug from any prefix.

[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.

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

Cut out almost all the optional code paths, drastically simplifying the
...
flow of control through this code.
We now always add PCI and PnP headers even for ISA ROMs; there's no harm
in doing so.
UNDI loader is still missing.

Prevent hundreds of errors from "make symcheck". The prefix exit path
...
mechanism has changed anyway, and so must be rewritten, but at least doing
this makes the output of "make symcheck" more legible.

#ifdef 0 out the UNDI loader routine, since it refers to the obsolete

callback mechanism.
