d64868cdcd Execute ON DISCONNECT triggers in the following cases: 
1. During database shutdown (gfix -shut full -force 0).
2. An attachment is deleted from MON$ATTACHMENTS by another attachment.
3. An attachment is closed by idle timeout.

ON DISCONNECT triggers will still not be executed during server shutdown.

Small meta name (#271) 
Keep metadata name strings in hash table having just a pointer to a hash table member in all places where metadata name is needed in order to save RAM. Hash table of metadata names is almost lock-less: mutex is used only when new segment of memory is needed or hash table should be grown.
