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.

Change the multilog code to toggle between async and sync writes for all
...
log types. This means the threaded_syslog type is no longer valid. A new
fxn multilog_async is available to toggle between the two modes. If an
app is compiled without pthreads and tries to use async logging, no logging
will occur while async is enabled.
dmeventd has been modified to use the new code
I'm not positive I like the way the async_logger code calls the log fxn,
but it works for now. Suggestions for other ways to do it would be helpful

o Changed the multilog API a bit (I warned you)
...
- multilog_add_type, multilog_del_type, multilog_custom, and
multilog_init_verbose all have different arguments.
- Primary change is that caller only passes in config info, and the
lib keeps track of state internally. No more exporting of
'struct log_data'.
- Custom callers now only get the custom data pointer passed into their
log fxn (that is set with multilog_custom)
- Added basic README that describes libmultilog
