This patch implements local username normalization using PRECIS (https://tools.ietf.org/html/rfc7564, https://tools.ietf.org/html/rfc7613) It makes chasquid accept local email and authentication regardless of the case. It covers both userdb and aliases. Note that non-local usernames remain untouched.
