PID [PIDAO] Token

EnumerableSet.getValues(EnumerableSet.Bytes4Set).bytes4Array_ (#180) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

VaultOwned.setVault(address) (#855-859) should emit an event for:
- _vault = vault_ (#856)
Emit an event for critical parameter changes.

Additional information: link

VaultOwned.setVault(address).vault_ (#855) lacks a zero-check on :
- _vault = vault_ (#856)
Check that the address is not zero.

ERC20Permit.permit(address,address,uint256,uint256,uint8,bytes32,bytes32) (#783-804) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= deadline,Permit: expired deadline) (#792)
Avoid relying on block.timestamp.
