by a factor of 16.

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().

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.

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

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...
