definitions in it. Begin to document the classes that we use, and how
they interrelate (using comments that I can use with doxygen to
automatically generate docs with).
expand one from using a fixed buffer to using a string which
dynamically allocates these things.

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.
'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.
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.
'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.
Noticed by: Gary Palmer
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
MFC After: 1 centiyear
o improve parsing and lexing
o create data structures based on the parsed file now.
o Still need to rewrite main loop and add regex (still uses hard coded
devd-generic)
o minor man page updates.
