Processing of pending invites on 3PID binding (#218)
* Add missing file headers * Move the ID server's signatures verification to common * Allow verification without specifying a server name * Add third-party structs to membership events content * Add processing of 3PID onbind requests * Use reference for third party invite data * Fix return arguments order * Revert "Move the ID server's signatures verification to common" This reverts commit 93442010316ce71a77ac58ffd3613754ce8fe969. * Revert "Allow verification without specifying a server name" This reverts commit fd27afbf82eac50fe9f7b83b26cfce3c66d530d2. * Remove checks that are already occurring in gomatrixserverlib * Change return type of createInviteFrom3PIDInvite * Add doc, add checks in fillDisplayName * Use MakeFedAPI * Invert condition * Use AuthEvents to retrieve the 3PID invite * Update comment * Remove unused parameter * gb vendor update github.com/matrix-org/gomatrixserverlib
