Add separate uplink/downlink flag for direct copy

Browse source 
For each connection, xtls need 4 flags for uplink/downlink reader/writer to decide when it switch to direct copy.
In the past, there were only one for read and one for write.
If service has xtls inbound and xtls outbound, the two flags may be corrupted by signal from different directions.
