0425e01683 According to devctl(4), clients must read events whole; they may not
piece them together from multiple reads().  It's as if /dev/devctl is
a datagram device instead of a stream device.  However, devd's
internal buffer was too small (1025 bytes) to read an entire
ereport.fs.zfs.checksum event (variable, up to ~1300 bytes).  This
commit enlarges the buffer to 8k.

842ccec57e Parse the ! lines that will soon be coming from the kernel. These are
a generalized notification mechanism for subsystems wishing to report
events.

6aeeca8edf Create a new C++ header file called devd.hh which has all the class
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).

3054f218eb MFp4 (imp_freebsd branch): snapshot of devd work:
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.

# There should be one more commit before rc2

e530e0446b 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.
