f731c31fa4 Use a bunch of weak symbols to determine which network components 
are present.  This works in userspace as opposed relying in link
sets, which fail miserably.  Later, when the networking stack
becomes modularized, we can move to a dynamic scheme like with file
systems.

Also, this change allows us to do proper autoconfig, namely attach
the loopback interface iff it is present.

9523c2be23 Add a dummyif, which doesn't actually traffic any cargo, but since 
it has no backend it can always be attached and is therefore
convenient for testing ifconfig.

7d6e9ec774 Support IPv6 in rump. I'd have liked to introduce a netinet6 
component, but due to ifdef happiness permeating the sources, it's
a compile decision for now, so netinet pulls in both inet and inet6.

One issue, one single issue: the loopback interface still needs to
be created for IPv6 to work.  I have patches to take care of it
automatically if the appropriate component (net) is present, but
they require a bit more testing before commit.

a4aff0cbb8 Add a virtual ethernet interface which uses shared memory as the 
bus instead of relying on the host kernel's tap and bridge.  This
is much lighterweight approach which does not consume non-pageable
kernel resources.

cc8bfe6c12 Fix a silly mistake: indubitably the struct ifnet pointer given to

a208c2294a Deal with the ld.so/linkset brokenness and compile all of libnet 
and libnetinet into a big bunch for now.  If they were separate
libraries, the DOMAIN_DEFINE() in the latter on the linkline would
not get noticed at "boot" time because of the abovementioned
brokenness.  One of these days I'll add code to dlopen() the
libraries and resplit them, but this will allow things to work
until then.

8a7a4b8184 Add a simple example of how to use rump networking facilities. 
This just contacts www.NetBSD.org, does GET / and displays the
result.

It either uses the host kernel socket provided PF_INET or the kernel
TCP/IP stack running in userspace (via if_virt and /dev/tap),
depending on the libraries it's linked with.

(not built yet, as I need to commit some more bits from my local
tree for it work)
