The tt_local_entry structure now has a 'flags' field. This helps to unify the flags format to all the client related structures (tt_global_entry and tt_change). The 'never_purge' field is now encoded in the 'flags' one. To optimise the usage of this field, its length has been increased to 16bit in order to use the eight leading bits (from 0 to 7) to store flags that have to be sent on the wire, while the eight ending ones are used for local computation only. Moreover 'enum tt_change_flags' is now called 'enum tt_client_flags' and the defined values apply to the tt_local_entry, tt_global_entry and the tt_change 'flags' field.
