In https://github.com/OpenZeppelin/openzeppelin-contracts-ethereum-package/pull/76, we are rearranging the erc721metadata contract storage layout, so the new variable is added at the end. This commit applies the same change to the vanilla contracts repository, so migration from 2.5 to 3.0 is easier for users using the transpiler.
* adding mock contacts, test code
* adding changes to ERC721.sol per @frangio's comments on original PR #1943
* fix solhint warnings
* Update contracts/token/ERC721/ERC721.sol

* 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.
* change revert msg assembly per PR comment by @frangio
* unify revert msg in test code
* fix some failed tests, wording change
* Update contracts/token/ERC721/ERC721.sol

* Changes ERC777 external functions to public for allowing overrides #1994
* Changes ERC777 external functions to public for allowing overrides (#1994)
* Update ReentrancyGuard for Istanbul Hard Fork
Changes:
Added L37, `_guardCounter = 1;`
Rationale:
The planned _Istanbul Hard Fork_ will implement [EIP 2200](e4d4ea348e/EIPS/eip-2200.md), which implements "net gas metering" for `sstore` operations. If the final value of `_guardCounter` is unchanged relative to the original value of it, a gas refund will be applied and charges for changing the value of `_guardCounter` will effectively not exist. This ends up being cheaper than the current implementation ONLY AFTER Istanbul. Before Istanbul, the added line actually ends up costing more gas.
Note that if `_guardCounter` is `0` initially, the initial cost and subsequent refund will both be larger than if `_guardCounter` is `1` initially. Although in both cases, the net gas cost (`gasCost - gasRefund`) are equal, it's better in terms of cost to have both the gas cost and refund smaller, as there is some limit to the percentage of a gas refund that can actually be realized.
