mod_auth_oauth_external: Allow different username in PLAIN vs final JID Mastodon for example having email addresses usernames in login, but a different username in the service itself. Thanks to @tcit@social.tcit.fr for the pointer to a usable validation endpoint for Mastodon, allowing this to be tested.

Introduction
============

In order to build heuristics for which messages are spam, it is necessary to
log as many details as possible about the spammers. This module sends a
version and disco query whenever a message is received from a JID to a user it
is not subscribed to. The results are printed to Prosody's log file at the
'info' level. Queried full JIDs are not queried again until Prosody restarts.

The queries are sent regardless of whether the local user exists, so it does
not reveal if an account is active.
