horde_activesync_cache.cahe_data  was growing too much for all my devices.
I realized that "synckeycounter" was to blame, and there was a synckey  
with a counter for every exchanged synckey and every collection.

Looking into code, "incrementLoopCounter" in  
Horde/ActiveSync/Collections.php was generating that data, but no  
function was checking or removing data from synckeycounter, so it just  
grows with every sync. I guess "checkLoopCounters" will do it in a  
future release.

Attached patch aims to be a way to clean a running database without  
having to do a whole clean and resync.
Commenting  "incrementLoopCounter"  in  
Horde/ActiveSync/Request/Sync.php will stop database growing but won't  
clean a running database.
