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...

Change semantics of network API so that packet-absorbing calls *always*
take ownership of the packet, rather than doing so only if they return
success. This breaks semantic compatibility with Linux's
hard_start_xmit() method, but means that we don't have to worry so much
about error cases.
Split mechanism of processing received packets (net_rx_process()) out
from policy (net_step()), preparatory to putting net_step() in a separate
object.

(librm_base-1b) is already an offset; no need to apply OFFSET().
Doing so, in fact, seems to expose an assembler bug; (a-b-0) is
apparently not the same as (a-b). Go figure.

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.

Network API now allows for multiple network devices (although the
implementation allows for only one, and does so without compromising on
the efficiency of static allocation).
Link-layer protocols are cleanly separated from the device drivers.
Network-layer protocols are cleanly separated from individual network
devices.
Link-layer and network-layer protocols are cleanly separated from each
other.
