Create a new type (xfs_dqtype_t) to represent the type of an incore dquot (user, group, project, or none). Rename the incore dquot's dq_flags field to q_type. This allows us to replace all the "uint type" arguments to the quota functions with "xfs_dqtype_t type", to make it obvious when we're passing a quota type argument into a function.
