Quentin Gliech fe1daad672 Move the "email unsubscribe" resource, refactor the macaroon generator & simplify the access token verification logic. (#12986) ... This simplifies the access token verification logic by removing the `rights` parameter which was only ever used for the unsubscribe link in email notifications. The latter has been moved under the `/_synapse` namespace, since it is not a standard API. This also makes the email verification link more secure, by embedding the app_id and pushkey in the macaroon and verifying it. This prevents the user from tampering the query parameters of that unsubscribe link. Macaroon generation is refactored: - Centralised all macaroon generation and verification logic to the `MacaroonGenerator` - Moved to `synapse.utils` - Changed the constructor to require only a `Clock`, hostname, and a secret key (instead of a full `Homeserver`). - Added tests for all methods.		2022-06-14 09:12:08 -04:00
