Make struct imsgev static like in the other routing daemons. With this
dvmrpd should compile with -fno-common

Kill dvrmpd_process and log_procnames. Unneeded abstraction for this
simple daemon.

Cleanup control like in the other routing daemons. Move control_state
and ctl_conns to control.c cleanup headers and the engine accordingly.

Another pkt_ptr cleanup. There is actually no need to make the pkt
a static memory region. Just use the stack.

work on making log.c similar in all daemons:

move daemon-local functions into new logmsg.c, and reduce
the (mostly whitespace) differences so that log.c's can be diffed easily.

Simplify shutdown process.

On shutdown, there's no need to use kill(2) to kill the child
processes. Just closing the IPC sockets will make the children receive
an EOF, break out from the event loop

Simplify shutdown process.

On shutdown, there's no need to use kill(2) to kill the child
processes. Just closing the IPC sockets will make the children receive
an EOF, break out from the event loop and then exit.

Tha advantages of this "pipe teardown" are:
* simpler code;
* no need to pledge "proc" in the parent process;
* removal of a (hard to trigger) PID reuse race condition.

Close connections when msgbuf_write() returns 0.

Don't fatal if the imsg pipe is closed, this is often triggered in the
parent and hides the real cause of the termination.

EAGAIN handling for imsg_read. OK henning@ benno@

More SOCK_NONBLOCK adjustments similar to the other daemons.

Nuke more obvious #include duplications.

LINK_STATE_IS_UP() cleanup userland part. There is no need to special
case carp(4) interfaces anymore. LINK_STATE_IS_UP() almost always does
the right job.

This needs a -current kernel or link state may be not reported correctly.

Rename some imsg bits to make namespace collisions less likely buf to
ibuf, buf_read to ibuf_read, READ_BUF_SIZE to IBUF_READ_SIZE.

React putting the interface in state 'down' when dvmrpd detects that
the link went down.

ok claudio@

make dvmrpd imsg-in-a-lib ready as well.
``put it in'' claudio@, ok eric@

Remove redundant imsg_event_add calls; ok claudio@

More libevent callback fixes. While there make n also ssize_t as in all
other daemons.

Initial support for pruning. When every single interface is removed from the
downstream list for a particular source send a prune to the upstream router.

Introduce support for flash updates.
They spread routing changes immediately as they happen
avoiding wait until the next report interval.

OK norby@

Remove some unneeded lint goo and use setres[ug]id() instead of the setuid
dance.

Welcome dvmrpd
started by Esben Norby some time ago by using the imsg/three process framework
of ospfd.
Right now it is not particularly useful, major parts are still missing but is
imported to allow more people to work on it.

Status:

The IGMP part is mostly complete, allowing clients to join and leave groups.
Election the IGMP querier of a network is also functional, only thing missing is
some corner cases when going from non-querier to querier.

About half of the DVMRP is functional, probes and route reports are functional.

Multicast streams can be detected and the MFC can be manipulated.
The RIB is not complete but operational.

Not yet connected to the builds.
