watchdogd v3.3

Changes

• Increased severity of syslog messages preceding reboot, instead of LOG_ERROR all messages that result in a reboot use LOG_EMERG because many syslogd services default to log emerg to console
• Add handy summary of options to configure script

Fixes

• Fix possible garbled next_ack for users of libwdog due to badly handled timeout in poll() when connecting to watchdogd
• Fix configure script defaults for the following settings:
  • --enable-compat, was always enabled
  • --enable-exampels, were always enabled
  • --enable-syslog-mark, was always enabled
• Fix use-after-free bug in new script monitor, introduced in v3.2
