Add support for federated avatars (#3320) * Add support for federated avatars Fixes #3105 Removes avatar fetching duplication code Adds an "Enable Federated Avatar" checkbox in user settings (defaults to unchecked) Moves avatar settings all in the same form, making local and remote avatars mutually exclusive Renames UploadAvatarForm to AvatarForm as it's not anymore only for uploading * Run gofmt on all modified files * Move Avatar form in its own page * Add go-libravatar dependency to vendor/ dir Hopefully helps with accepting the contribution. See also #3214 * Revert "Add go-libravatar dependency to vendor/ dir" This reverts commit a8cb93ae640bbb90f7d25012fc257bda9fae9b82. * Make federated avatar setting a global configuration Removes the per-user setting * Move avatar handling back to base tool, disable federated avatar in offline mode * Format, handle error * Properly set fallback host * Use unsupported github.com mirror for importing go-libravatar * Remove comment showing life exists outside of github.com ... pity, but contribution would not be accepted otherwise * Use Combo for Get and Post methods over /avatar * FEDERATED_AVATAR -> ENABLE_FEDERATED_AVATAR * Fix persistance of federated avatar lookup checkbox at install time * Federated Avatars -> Enable Federated Avatars * Use len(string) == 0 instead of string == "" * Move import line where it belong See https://github.com/Unknwon/go-code-convention/blob/master/en-US/import_packages.md Pity the import url is still the unofficial one, but oh well... * Save a line (and waste much more expensive time) * Remove redundant parens * Remove an empty line * Remove empty lines * Reorder lines to make diff smaller * Remove another newline Unknwon review got me start a fight against newlines * Move DISABLE_GRAVATAR and ENABLE_FEDERATED_AVATAR after OFFLINE_MODE On re-reading the diff I figured what Unknwon meant here: https://github.com/gogits/gogs/pull/3320/files#r73741106 * Remove newlines that weren't there before my intervention

Oauth2 consumer (#679) * initial stuff for oauth2 login, fails on: * login button on the signIn page to start the OAuth2 flow and a callback for each provider Only GitHub is implemented for now * show login button only when the OAuth2 consumer is configured (and activated) * create macaron group for oauth2 urls * prevent net/http in modules (other then oauth2) * use a new data sessions oauth2 folder for storing the oauth2 session data * add missing 2FA when this is enabled on the user * add password option for OAuth2 user , for use with git over http and login to the GUI * add tip for registering a GitHub OAuth application * at startup of Gitea register all configured providers and also on adding/deleting of new providers * 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)
