At a point not too far in the future, we will be switching from the
hardcoded MINIX3 implementation of the getifaddrs(3) libc routine to
the proper NetBSD implementation. The latter uses the
net.route.rtable sysctl functionality to obtain its information. In
order make the transition as painless as possible, this patch adds
basic support for that net.route.rtable functionality to INET and
LWIP, using the remote MIB (RMIB) facility.

Previously, services would obtain the user ID of "service" through
getpwnam(3). While this approach is conceptually better, it also
imposes linking against libc which in turn causes problems with
printf(3), which already led to PFS no longer dropping privileges at
all. For now, we hardcode SERVICE_UID and use that instead.
In the future, two changes should allow removal of SERVICE_UID again:
- "service edit" should cause RS to request that a service (such as
PFS) drop privileges through SEF, using the user ID resolved by
service(8), or something similar;
- a future devfs should make it possible for inet to start without
root privileges altogether.

- synchronize request type with ioctl by making it unsigned long;
- unbreak VFS requests, as they were being sent to PM;
- use proper ioctl direction flags (and new numbers) for requests;
- remove some needless header inclusions;
- svrctl is in libc, make its message name reflect this;
- keep backward compatibility: svrctl is part of the userland ABI.
