This PR:

  • adjusts the AssetsFrom filter to allow for suffixes longer than 1 Junction to be compatible with the new PalletInstance prefix introduced by Update XCM MultiLocation prefixes for assets #831
    • and adds some XCM tracing.
  • sets Statemint (Parachain 1000) as a trusted reserve for relay chain tokens.

Questions coming out of this:

XCM v3 might take a while to be merged. I can just create an issue to track this.

@KiChjang @NachoPal : Is this still a change we want/need? Let's merge master or close it.

IIRC, the discussion we had before was that Statemint/e shouldn't view the relay chain as a reserve for DOT/KSM as it can cause problems with reserves drainage via the mixed usage of asset teleportation and reserve transfers. Given so, we probably do not need to allow Statemint to recognize the relay chain as a reserve.

However, the AssetsFrom filter change still makes sense to me.
