/**
 * @dev Extension of {AccessControl} that allows specifying special rules to manage
 * the `DEFAULT_ADMIN_ROLE` holder, which is a sensitive role with special permissions
 * over other roles that may potentially have privileged rights in the system.
 *
 * If a specific role doesn't have an admin role assigned, the holder of the
 * `DEFAULT_ADMIN_ROLE` will have the ability to grant it and revoke it.
 *
 * This contract implements the following risk mitigations on top of {AccessControl}:
 *
 * * Only one account holds the `DEFAULT_ADMIN_ROLE` since deployment until it's potentially renounced.
 * * Enforces a 2-step process to transfer the `DEFAULT_ADMIN_ROLE` to another account.
 * * Enforces a configurable delay between the two steps, with the ability to cancel before the transfer is accepted.
 * * The delay can be changed by scheduling, see {changeDefaultAdminDelay}.
 * * It is not possible to use another role to manage the `DEFAULT_ADMIN_ROLE`.
 *
 * Example usage:
 *
 * ```solidity
 * contract MyToken is AccessControlDefaultAdminRules {
 *   constructor() AccessControlDefaultAdminRules(
 *     3 days,
 *     msg.sender // Explicit initial `DEFAULT_ADMIN_ROLE` holder
 *    ) {}
 * }
 * ```
 *
 * _Available since v4.9._

 * Roles are referred to by their `bytes32` identifier. These should be exposed
 * in the external API and be unique. The best way to achieve this is by
 * using `public constant` hash digests:
 *
 * ```solidity
 * bytes32 public constant MY_ROLE = keccak256("MY_ROLE");
 * ```
 *
 * Roles can be used to represent a set of permissions. To restrict access to a
 * function call, use {hasRole}:
 *
 * ```solidity
 * function foo() public {
 *     require(hasRole(MY_ROLE, msg.sender));
 *     ...
 * }
 * ```
 *
 * Roles can be granted and revoked dynamically via the {grantRole} and
 * {revokeRole} functions. Each role has an associated admin role, and only
 * accounts that have a role's admin role can call {grantRole} and {revokeRole}.
 *
 * By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means
 * that only accounts with this role will be able to grant or revoke other
 * roles. More complex role relationships can be created by using
 * {_setRoleAdmin}.
 *
 * WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to
 * grant and revoke this role. Extra precautions should be taken to secure
 * accounts that have been granted it. We recommend using {AccessControlDefaultAdminRules}
 * to enforce additional security measures for this role.
