853460b20d 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.

2fedabd3b9 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

ee11aa9e75 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.

ed1b3a023c Another ioctl interface update: 
Supply offset to start of variable data area (so struct size can change
without breaking backward compatibility)
  Add command that just returns the driver version

49588ccd98 Some ioctl interface changes. (Do we want these?) 
- use status bits (so we can add flags without changing the struct size)
  - use dev_t
