Some OAuth2 providers return quite large structured tokens >32767 bytes.
Gitea currently has a fixed maximum of 32767 bytes for these and
unfortunately due to the convoluted nature of the dependent libraries the
error returned is rather opaque.
Here we manage the error a little better - detecting the rather opaque
github.com/gorilla/securecookie.errEncodedValueTooLong and converting
it to a more readable error.
Further we provide a configurable option to increase the maximum size of
the provided OAuth2 tokens.

* custom handling of errors in oauth2 request init + show better tip
* add ExternalLoginUser model and migration script to add it to database
* link a external account to an existing account (still need to handle wrong login and signup) and remove if user is removed
* remove the linked external account from the user his settings
* if user is unknown we allow him to register a new account or link it to some existing account
* sign up with button on signin page (als change OAuth2Provider structure so we can store basic stuff about providers)
* from gorilla/sessions docs:
"Important Note: If you aren't using gorilla/mux, you need to wrap your handlers with context.ClearHandler as or else you will leak memory!"
(we're using gorilla/sessions for storing oauth2 sessions)
* use updated goth lib that now supports getting the OAuth2 user if the AccessToken is still valid instead of re-authenticating (prevent flooding the OAuth2 provider)
