Also retire support for the MINIX versions of /etc/hosts and
/etc/resolv.conf. These files will be brought back with NetBSD
imports, although like NetBSD, MINIX 3 will be using external
resolvers directly from then on. Since resolv.conf is hand-created
rather than installed, we do not mark it as obsolete.

UDS: full rewrite

This new implementation of the UDS service is built on top of the
libsockevent library. It thereby inherits all the advantages that
libsockevent brings. However, the fundamental restructuring
required for that change also paved the way for resolution of a
number of other important open issues with the old UDS code. Most
importantly, the rewrite brings the behavior of the service much
closer to POSIX compliance and NetBSD compatibility. These are the
most important changes:

- due to the use of libsockevent, UDS now supports multiple suspending
calls per socket and a large number of standard socket flags and
options;
- socket address matching is now based on <device,inode> lookups
instead of canonized path names, and socket addresses are no longer
altered either due to canonization or at connect time;
- the socket state machine is now well defined, most importantly
resolving the erroneous reset-on-EOF semantics of the old UDS, but
also allowing socket reuse;
- sockets are now connected before being accepted instead of being
held in connecting state, unless the LOCAL_CONNWAIT option is set
on either the connecting or the listening socket;
- connect(2) on datagram sockets is now supported (needed by syslog),
and proper datagram socket disconnect notification is provided;
- the receive queue now supports segmentation, associating ancillary
data (in-flight file descriptors and credentials) with each segment
instead of being kept fully separately; this is a POSIX requirement
(and needed by tmux);
- as part of the segmentation support, the receive queue can now hold
as many packets as can fit, instead of one;
- in addition to the flags supported by libsockevent, the MSG_PEEK,
MSG_WAITALL, MSG_CMSG_CLOEXEC, MSG_TRUNC, and MSG_CTRUNC send and
receive flags are now supported;
- the SO_PASSCRED and SO_PEERCRED socket options are replaced by
LOCAL_CREDS and LOCAL_PEEREID respectively, now following NetBSD
semantics and allowing use of NetBSD libc's getpeereid(3);
- memory usage is reduced by about 250 KB due to centralized in-flight
file descriptor tracking, with a limit of OPEN_MAX total rather than
of OPEN_MAX per socket;
- memory usage is reduced by another ~50 KB due to removal of state
redundancy, despite the fact that socket path names may now be up to
253 bytes rather than the previous 104 bytes;
- compared to the old UDS, there is now very little direct indexing on
the static array of sockets, thus allowing dynamic allocation of
sockets more easily in the future;
- the UDS service now has RMIB support for the net.local sysctl tree,
implementing preliminary support for NetBSD netstat(1).
