Add session context outbounds as slice (#3356)
* Add session context outbounds as slice

slice is needed for dialer proxy where two outbounds work on top of each other
There are two sets of target addr for example
It also enable Xtls to correctly do splice copy by checking both outbounds are ready to do direct copy

* Fill outbound tag info

* Splice now checks capalibility from all outbounds

* Fix unit tests

a15334b395 Go back to first fix (revet d21e9b0abd)
Xtls is magic, don't play with it ;)

A knowledged guess is the timing to switch to splice is very sensitive. Now both Xtls and Freedom outound do the switching when pipe just finished one buffer

d21e9b0abd Try a better fix for rare ssl error with freedom splice
It seems the root cause is if the flag set at the inbound pipe reader, it is a race condition and freedom outbound can possibly do splice at the same time with inbound xtls writer.
Now we set the flag at the earliest and always do splice at the next buffer cycle.

d6d225c698 Refactor Vision reader writer
- Vision now use traffic states to capture two-way info about a connection
- XTLS is de-couple with Vision, it only read traffic states to switch to direct copy mode
- fix a edge case error when Vision unpadding read 5 command bytes

Vision padding upgrade (#1646)
* Vision server allow multiple blocks of padding

* Fix Vision client to support multiple possible padding blocks

* Vision padding upgrade

- Now we have two types of padding: long (pad to 900-1400) and traditional (0-256)
- Long padding is applied to tls handshakes and first (empty) packet
- Traditional padding is applied to all beginning (7) packets of the connection (counted two-way)
- Since receiver changed its way to unpad buffer in fd6973b3c6, we can freely extend padding packet length easily in the future
- Simplify code

* Adjust receiver withinPaddingBuffers

Now default withinPaddingBuffers = true to give it a chance to do unpadding

* Fix magic numbers for Vision
Thanks @H1JK

Thanks @RPRX for guidance

Insert padding with empty content to camouflage VLESS header (#1610)
This only affects the Vision client for protocols expecting server to send data first.
The change is compatible with existing version of Vision server.

1d7c40d728 Enable Xtls Vision (Direct not Splice) for any inbound connection
Before this change, Vision client need a pure inbound like socks or http.
After this change, it will support any inbound.
This is useful in traffic forwarder use case inside China.
