mrouted v4.7

Fixes

• Validate the length fields when parsing DVMRP INFO_REQUEST. A request
  claiming more data than the packet holds, and a full size packet of well
  formed requests, both made the parser and the reply it builds run past the
  buffers they work on. Reported by Tristan Madani
• Fix route reports received on a blaster interface, which never survived the
  replay. Queued reports were replayed with a negated length in a size_t
  argument, wrapping it. Blaster support has not worked since v3.9.1. Reported
  by Tristan Madani
• Fix mroutectl reading one byte before the start of its line buffer on a line
  that holds nothing but newlines
• Fix mrouted exiting when an interface is deleted while another one is down.
  The periodic interface check treats a failed SIOCGIFFLAGS as fatal, and it
  only runs while some interface is known to be down

Changes

• Issue #39: allow the loopback interface to be used for routing. It has to be
  multicast capable and carry a routable address, Linux sets up neither on lo
  by default. The 127.0.0.0/8 address is skipped, and a loopback VIF is always
  passive, no neighbor can be reached over it
• Issue #63: new mroutectl reload ifaces command. It rescans the kernel
  interface list, brings interfaces that have appeared since startup into
  service, and takes the ones that are gone out of it, keeping the routes and
  prunes already learned. Interfaces that did not change keep the VIF number
  they had. mrouted.conf is not re-read, an interface that needs settings
  from it still calls for a restart. Original patch by Carlos Guimarães
• Drop the container image, ghcr.io/troglobit/mrouted is no longer updated.
  mrouted needs the interfaces it routes between in its own network namespace,
  which takes them away from the host, so the image was of little use
