Add lwip: a new lwIP-based TCP/IP service

This commit adds a new TCP/IP service to MINIX 3. As its core, the
service uses the lwIP TCP/IP stack for maintenance reasons. The
service aims to be compatible with NetBSD userland, including its
low-level network management utilities. It also aims to support
modern features such as IPv6. In summary, the new LWIP service has
support for the following main features:

- TCP, UDP, RAW sockets with mostly standard BSD API semantics;
- IPv6 support: host mode (complete) and router mode (partial);
- most of the standard BSD API socket options (SO_);
- all of the standard BSD API message flags (MSG_);
- the most used protocol-specific socket and control options;
- a default loopback interface and the ability to create one more;
- configuration-free ethernet interfaces and driver tracking;
- queuing and multiple concurrent requests to each ethernet driver;
- standard ioctl(2)-based BSD interface management;
- radix tree backed, destination-based routing;
- routing sockets for standard BSD route reporting and management;
- multicast traffic and multicast group membership tracking;
- Berkeley Packet Filter (BPF) devices;
- standard and custom sysctl(7) nodes for many internals;
- a slab allocation based, hybrid static/dynamic memory pool model.

Many of its modules come with fairly elaborate comments that cover
many aspects of what is going on. The service is primarily a socket
driver built on top of the libsockdriver library, but for BPF devices
it is at the same time also a character driver.

Import NetBSD ndp(8)

Like arp(8), this utility already uses the NetBSD 8 protocol for
talking to the operating system through routing sockets.

Like arp(8), this utility is not fully functional, due to limitations
of lwIP. While ndp(8) should provide a proper (read-only) view of the
contents of the Neighbor Discovery table, any attempts to modify the
table will fail. In addition, various other ndp(8) features are not
supported. On MINIX 3, the prefix and default router lists are not
managed by the operating system however, but rather by dhcpcd(8);
therefore, an implementation of the features related to those lists
would not provide any actual functionality.

Import NetBSD tcpdump(8)

For now, printing of Sun RPC requests is disabled because we do not
yet have the RPC header files. This should affect basically noone,
as we do not have any RPC-based programs yet, for the same reason.

Import NetBSD libpcap

As part of this, we import bpf_filter.c from NetBSD. Even though that
file is part of the NetBSD kernel, it is also used by userland (as is
clear here). Our LWIP service has its own bpf_filter.c implementation
but that implementation has certain limits (e.g. on program size) that
are fine for a system service but should not apply to userland.

The libpcap code has a number of blocks guarded by __NetBSD__, but
none of those blocks apply to MINIX 3. In particular, some of the
alignment logic used for NetBSD may in fact not work in our case.
