Description David Teigland 2012-08-17 11:46:28 EDT 
Description of problem:

The watchdog would not fire at the correct time if the wdmd process was
killed near the firing time, or killed and restarted near the firing time.
The time until the watchdog fired was also not being correctly calculated
by sanlock.

test: killall -9 wdmd, service wdmd start (should fail), watchdog should
reboot machine

test: existing failure/recovery tests should continue to work the same

commits
wdmd: use shm_open to prevent restart
daemon: extend grace time
wdmd: close device when test fails
wdmd: preemptive close before test fails
wdmd: pet after reopen and use 1 sec interval after failure
sanlock: base kill sig on last renewal
