Summary:                    [patch] devicestate is not aggregated from all
received events
Description: 
When distributed devicestate (res_ais) is used, Asterisk should calculate
an aggregated device state based on local and received device states. This
is currently not done.

    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.
