c511ec0ad8 Convert devd's client socket to type SOCK_SEQPACKET.
This change consists of two merges from projects/zfsd/head along with the
addition of an ATF test case for the new functionality.

sbin/devd/tests/Makefile
sbin/devd/tests/client_test.c
	Add ATF test cases for reading events from both devd socket types.

r266519:
sbin/devd/devd.8
sbin/devd/devd.cc
	Create a new socket, of type SOCK_SEQPACKET, for communicating with
	clients. SOCK_SEQPACKET sockets preserve record boundaries,
	simplying code in the client. The old SOCK_STREAM socket is retained
	for backwards-compatibility with existing clients.

r269993:
sbin/devd/devd.8
	Fix grammar bug.

16596db60f Add syslog(3) support to devd(8).
sbin/devd/devd.cc
        All output will now go to syslog(3) if devd is daemonized, or stderr
        if it's running in the foreground.

sbin/devd/devd.8
        Remove the "-D" flag.  Filtering messages by priority now
	happens in the usual syslog way.  For performance reasons, a few
	extra-verbose debugging statements are now conditional on the "-d" (do
	not daemonize) flag.

etc/syslog.conf
etc/newsyslog.conf
        Direct messages from devd(8) to /var/log/devd.log, but leave it
        disabled by default

3e5ced1b98 Fix a descriptor leak in devd. Clients reading /var/run/devd.pipe can close
their socket connection any time, and devd only notices that when it gets an
error trying to write an event to the client.  On a system with no device
change activity, clients could connect and disappear repeatedly without devd
noticing, leading to an ever-growing list of open socket descriptors in devd.

Now devd uses poll(2) looking for POLLHUP on all existing clients every time
a new client connection is established, and also periodically (once a minute)
to proactively find zombie clients and reap the socket descriptors.  It also
now has a connection limit, configurable with a new -l <num> command line arg.
When the maximum number of connections is reached it stops accepting new
connections until some current clients drop off.

037b7ed675 Implement a two new flags, and change the meaning of another one.
'd': now means don't do daemon().
'D': Debug
'n': Don't wait to process all pending events before calling daemon.

In the past, devd would call daemon immediately.  However, this causes
a race.  If anything in the boot process depends on configuring the
devices configured by devd, maybe they would be configured in time,
maybe not.  Now we don't call daemon until all pending events are
processed, unless -n is specified.

# -n is actually the default for a while due to the select(2) bug in devctl
# that I just fixed to give people a chance to upgrade.

825b39f9a0 devd. A daemon that hooks into the kernel's /dev/devctl to produce
arbitrary commands when devices come and go in the device tree (which is
different than the /dev directory).

This is an initial version.  Much of the planned power isn't here.
Instead of doing the full matching, we always run /etc/devd-generic.
/etc/devd.generic will go away at some point, I think.

I'm committing it in this early state so I can start getting feedback
from early adapters.
