Preserve the whole of %esp across prot_call(). We have to split this
between the low half stored in the static variable rm_sp, and the high
half stored on the prot_call() stack, because:
Just using the stack would screw up when a prot_call()ed routine
executes a real_call(); it would have no way to find the current top of
the RM stack.
Extending rm_sp to rm_esp would not be safe, because the guarantee that
rm_sp must return to the correct value by the time an external
real-mode call returns applies only to %sp, not to %esp.

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.

Added methods for efficiently declaring and accessing variables in

address of the start of .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.

<name>_size variable is no longer needed, since we don't copy the code.
However, it's worth adding a .size directive so that objdump reports the

This should be much more elegant: we use flat real mode for the

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

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.
