net: Add support for capturing VLANs (Jan Kiszka)

This patch is derived from Tristan Gingold's patch. It adds a new VLAN
client type that writes all traffic on the VLAN it is attached to into a
pcap file. Such a file can then be analyzed offline with Wireshark or
tcpdump.

Besides rebasing and some minor cleanups, the major differences to the
original version are:
 - support for enabling/disabling via the monitor (host_net_add/remove)
 - no special ordering of VLAN client list, qemu_send_packet now takes
   care of properly ordered packets
 - 64k default capturing limit (I hate tcpdump's default)
