  Fix cache of device state changes for multiple servers.
  
  This patch addresses a regression where device states across multiple servers
  were not being processing completely correctly.  The code works to determine
  the overall state by looking at the last known state of a device on each
  server.  However, there was a regression due to some invasive rewrites of how
  the cache works that led to the cache only storing the last device state change
  for a device, regardless of which server it was on.
  
  The code is set up to cache device state change events by ensuring that each
  event in the cache has a unique device name + entity ID (server ID).  The code
  that was responsible for comparing raw information elements (which EID is)
  always returned a match due to a memcmp() with a length of 0.
  
  There isn't much code to fix the actual bug.  This patch also introduces a new
  CLI command that was very useful for debugging this problem.  The command
  allows you to dump the contents of the event cache.
