Upgrade rumpkernel package to rump 10.99.12

[Damien Zammit]

Hi,

I would like to suggest the following upgrade of rump to be on par with
my "develop" branch[1].  The patches would need to be fetched from my 
branch directly because there is a very large changeset in the NetBSD 
upstream update commit.

The main thing is upgrading rump from 9.99.x to 10.99.x
Thanks to E. Brateau for most of this work, (I debugged a few things
on top of that).

This branch works with rumpdisk and rumpusbdisk under qemu and on x86
hardware, and sets up bpf so we can continue working on rumpnet.

There is a remaining problem with -smp 2 and -smp 1 hanging on startup
with an smp gnumach, but that was also an issue before this change.
