5469414bf8 Timeout event implementation: 
The daemon side of this is mostly the same as the patch I sent out.  To select
a timeout period different than the default and to get the timeout period,
I added two library calls, dm_set_event_timeout() and dm_get_event_timeout().
If people are against them, the other option is to tack extra arguments onto
dm_regiser_for_event() and dm_get_registered_device().  I also added a
-t option to dmevent, so people can try out timeouts.

cd4355d8f4 o stick multilog into the dm-event lib and dmeventd code again 
o more tweaks to libmultilog calls - the api isn't set in stone yet, so
   don't get too comfortable.
 o not sure the dmeventd in device-mapper/dmeventd works - i've been using
   the one in lib/event/
 o currently both daemons are set to log only to syslog

18f3ec8297 o Long-awaited ioctl interface clean-up. *** Not backwardly compatible *** 
o Various other kernel side tidy-ups.
o Version number changes so we have the option of adding new ioctl commands
  in future without affecting the use of existing ones should you later
  revert to an older kernel but not revert the userspace library/tools.
o Better separation of kernel/userspace elements in the build process to
  prepare for independent distribution of the kernel driver.

00ee56e232 Use additional version numbers. 
Kernel driver has a version number (stored in kernel/VERSION).
  The first two components of this (0.94) give the version number of the
  ioctl interface.  This number must be changed whenever a change is
  made to the ioctl interface that breaks backwards compatibility.

  The library has a version number (stored in VERSION) which is
  used for linking.
  The first and/or second component of this must be changed whenever
  a change is made to the library API that breaks backwards
  compatibility.
