init_librm() and prot_call() are now real-mode far calls.
...
install() now calls relocate(), moves the protected-mode code to the new
location, and calls hide_etherboot().

Restructured PCI subsystem to fit the new device model.
...
Generic PCI code now handles 64-bit BARs correctly when setting
"membase"; drivers should need to call pci_bar_start() only if they want
to use BARs other than the first memory or I/O BAR.
Split rarely-used PCI functions out into pciextra.c.
Core PCI code is now 662 bytes (down from 1308 bytes in Etherboot 5.4).
284 bytes of this saving comes from the pci/pciextra split.
Cosmetic changes to lots of drivers (e.g. vendor_id->vendor in order to
match the names used in Linux).

Add infrastructure to support access to .data16 (and .text16) variables
...
from protected-mode code.
Set up %ds to point to .data16 in prot_to_real, so that code specified
via REAL_EXEC() and friends can access variables in .data16.
Move most real-mode librm variables from .text16 to .data16.

BSS is now zeroed by libprefix (along with the otherwise non-zeroable
...
portions such as the stack) during the installation process.
init_fns() are called from main(). We need to think about initial
control flow some more.

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.

This should be much more elegant: we use flat real mode for the
...
highmem data, so decompress16 will be able to unpack blocks bigger
than 64kB.

Checking in because I don't want to lose this rather neat code for
...
running the decompresser in 16:16 protected mode using the real-mode
stack. However, there's an even simpler way to do it...

Header rearrangement.
...
I want to get to the point where any header in include/ reflects a
standard user-level header (e.g. a POSIX header), while everything that's
specific to gPXE lives in include/gpxe/. Headers that reflect a Linux
header (e.g. if_ether.h) should also be in include/gpxe/, with the same
name as the Linux header and, preferably, the same names used for the
definitions.

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.
