ff0432665a Parse the ! lines that will soon be coming from the kernel. These are
a generalized notification mechanism for subsystems wishing to report
events.

# The kernel side seems like it might be causing panics for me, but should

d2464b0086 At imp's request, force devd to be statically compiled. This avoids the
need for libstdc++ in /lib, and the generated binary is actually smaller
statically linked than dynamically + sizeof(libstdc++). Additionally,
devd doesn't use get*by*() which is one of the main motivations for
dynamically linking your root partition anyway.

e01c3427e3 Allow zero or more actions in an action list, rather than requiring
one or more actions in the list.  This makes constructs like:

attach 10 {
//	echo "Driver $device_name attached"
};

to be accepted by the parser.  It will be treated as if the user had
entered:

// attach 10 {
//	echo "Driver $device_name attached"
// };

(eg totally ignored).

0016700b2e sysctlbyname takes a size_t as its 5th argument, not a pointer.
However, since NULL was used, and this is C++, this error went
undetected until g++ 3.3 somehow managed to whine about it.

they interrelate (using comments that I can use with doxygen to

71f3be54cc Change default to be 'process all events before calling daemon.'
Also, put a small work around into devd to prevent a hang on boot this
would cause because select used to return 2 rather than 0 for no
evetnts due to a bug I fixed a few days ago in subr_bus.c.  I'll
remove this workaround May 7th.  You have until then to upgrade your
kernel if you want to run a new devd with an older kernel.

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.

6968b9e7d3 Put an anti-foot-shooting measure in place. Set hw.bus.devctl_disable
to 0 when we startup.  Print a warning in this case.  This allows
people that are playing with devd by hand to have something happen.
Otherwise, it appears that devd isn't working because /dev/devctl is
disabled and producing no events.

Suggested by: peter on irc a long time ago.

304876f035 o Skip white space between variables better. This makes
'a="b" c="d" at loc=1 on busN' properly set 'c' and process the rest of
  the stirng.  Before it would ignore everything after variable 'a'.
o Parse nomatch and other events differently.  They are more different
  than the code allowed for, so we weren't properly parsing nomatch
  events.  It appears this fixes some of the demand loading issues that
  I was having with devd.

150f6d2e0e MFp4: make it work
o Expand variables correctly.
o Set variables for each event.
o rewrite event loop to execute the commands in the config file, rather
  than the hard wired generic command
o better(?) debug when running -d
o sort vectors of actions so that we just have to search for the first
  one to match rather than the best one that matches.
o better attempts to clear all resources used on 'restart'
o Remove now bogus comments

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.
