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
* chore: fix some errors detected by staticcheck
* feat: remove `rand.Seed()` usage for possibly using "fastrand64" runtime to avoid locking
ref: https://pkg.go.dev/math/rand#Seed
* Add fingerprint xray_random
xray_random means to pick a random uTLS fingerprint at the core startup
This way, the fingerprint is stable for a user for some days. While there is no identifiable signature for the whole xray community
* Fingerprint "random" refine
Exclude old fingerprint from RNG
