0321b694c7 - Add support for a "!" character in regex matching in devd(8). It inverts
the logic (true/false) of the matching.

- Add "!usbus[0-9]+" to IFNET ATTACH notification handler in the default
  devd.conf to prevent rc.d/netif from running when usbus[0-9]+ is attached.

b8f92ce4de Expand system into my_system, and add the necessary tidyness that we
need.  Close the pidfile.  Then close all descriptors >= 3 to avoid
information leakage to children.

This solves the problem of not being able to restart devd when you
have, for example, a dhclient forked to configure your network...

4a3050fc46 o Yacc's lineno variable holds a total number of parsed lines.
Reset it to 1 for each devd config file so if the parser finds
a syntax error devd(8) will report a correct line number.

de02eec866 As pointed out on current@, we don't want to declare a variable in a scope
that just uses the variable and throws it away.

This should fix the subsystem keyword wrt media-type.

79f92e2597 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.

812f53a7b5 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.

5a882d775d 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.

9c1808986c 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.

b1ee04b18e 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.

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
