Allow access to variables in .text16 as well as .data16. Chained
interrupt vectors, for example, will be easiest to handle if placed in
.text16.

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
.data16. librm will need to supply "char *data16", i.e. the virtual
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.

Create two easy-to-use entry points in libprefix: install and
install_prealloc. I *think* these will suffice for all the 16-bit
prefixes.

<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
correct sizes for the code fragments.

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.
