* Clean code
- using type().interfaceId to improve readeability of ERC165 registration
- hardcoding some keccak256 that are otherwise computed at construction.
* hardcode keccak256 result
* Improve code readeability using try/catch
* Remove hardcoded hash
tests show that solc 0.8.0 does the optimization as expected
* Use try/catch to improve readability
* ERC165Checker: Do not revert when returndata is empty + new test
* Address PR comments
* improve testing of ERC721Receiver errors
* put back comment about invalid interface id
* coverage does not support 0.8.1. Reverting back to 0.8.0
* bubble all data with length > 0 if onERC721Receive fails.
* Fix test: revert without message trigger is bubble with the default message
* using enum object to improve readability
* Initial ERC1155 implementation with some tests (#1803)
* Initial ERC1155 implementation with some tests
* Remove mocked isERC1155TokenReceiver
* Revert reason edit nit
* Remove parameters associated with isERC1155TokenReceiver call
* Add tests for approvals and single transfers
* Add tests for transferring to contracts
* Add tests for batch transfers
* Make expectEvent.inTransaction tests async
* Renamed "owner" to "account" and "holder"
* Document unspecified balanceOfBatch reversion on zero behavior
* Ensure accounts can't set their own operator status
* Specify descriptive messages for underflow errors
* Bring SafeMath.add calls in line with OZ style
* Explicitly prevent _burn on the zero account
* Implement batch minting/burning
* Refactored operator approval check into isApprovedForAll calls
* Renamed ERC1155TokenReceiver to ERC1155Receiver
* Added ERC1155Holder
* Fix lint issues
* Migrate tests to @openzeppelin/test-environment
* port ERC1155 to Solidity 0.6
* make ERC1155 constructor more similar to ERC721 one
* also migrate mock contracts to Solidity 0.6
* mark all non-view functions as virtual
* add simple catch-all implementation for the metadata URI interface
* include an internal function to set the URI so users can implement functionality to switch URIs
* add tests for ERC1155 metadata URI
* fix nits, mostly pointed out by linter
* convert ERC1155 metadata URI work to Solidity 0.6
* mark all non-view functions as virtual
* Port ERC 1155 branch to Solidity 0.6 (and current master) (#2130)
* port ERC1155 to Solidity 0.6
* make ERC1155 constructor more similar to ERC721 one
* also migrate mock contracts to Solidity 0.6
* mark all non-view functions as virtual
* Update contracts/token/ERC1155/IERC1155MetadataURI.sol
Starting on Solidity v0.6.2, interfaces can now inherit. \o/

* same revert wording per @frangio's review suggestion
* per @frangio's feedback, changing the inline assembly to accomplish: we want to ignore the first 4 bytes of content, so we should read the length and decrease it by 4, then take the memory location and add 4 to it, then store the new length at the new memory location, then that is the new byte array that we want.
