Browse Source 
* add foreign assets to westmint

* add foreign assets to statemine

* use updated api for ensure origin trait

* Assets/ForeignAssets tests and fixes (#2167)

* Test for create and transfer `TrustBackedAssets` with AssetTransactor

* Test for transfer `local Currency` with AssetTransactor

* Test for create foreign assets (covers foreign relaychain currency)

* Added `ForeignFungiblesTransactor` and test for transfer `ForeignAssets` with AssetTransactor

* Removed unused `pub const Local: MultiLocation`

* Changed `ParaId -> Sibling` for `SiblingParachainConvertsVia`

* Test for create foreign assets (covers local sibling parachain assets)

* Reverted stuff for ForeignCreators from different global consensus (moved to transfer asset branch)

* Refactor `weight_limit` for `execute_xcm`

* Added test for `set_metadata` by ForeignCreator with `xcm::Transact(set_metadata)`

* Renamed `receive_teleported_asset_works` -> `receive_teleported_asset_for_native_asset_works`

* Allow `ForeignCreators` only for sibling parachains

* Unify ReservedDmpWeight/ReservedXcmpWeight usage

* Removed hack - replaced with `MatchedConvertedConcreteId`

* Refactor `ForeignCreators` to assets-common

* Add `ReceiveTeleportedAsset` test

* Change test - `Utility::batch` -> Multiple `xcm::Transact`

* Reusing the same deposits as for TrustBackedAssets

* missing `try_successful_origin` ?

* Finished `ForeignAssets` for westmint (converter, FungiblesApi, tests)

* Refactoring tests - receive_teleported_asset_for_native_asset_works

* ForeignAssets for statemine + refactored `receive_teleported_asset_from_foreign_creator_works`

* Add `ForeignAssets` to statemine `FungiblesApi`

* Add `asset_transactor_transfer_with_local_consensus_currency_works` to all runtimes

* Added `asset_transactor_transfer_with_trust_backed_assets_works` test

* Added `asset_transactor_transfer_with_foreign_assets_works`

* Fix `missing `try_successful_origin` in implementation`

* Added `create_and_manage_foreign_assets_for_local_consensus_parachain_assets_works`

* Added `ExpectTransactStatus` check

* Small rename

* Extended `test_assets_balances_api_works` with ForeignAssets for `statemine`

* PR fixes
