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.
