Bryan Davis a6b60d2465 Apply rate limits to all token verifications
Extend the token validation failure checks introduced in I4884f6e to the
other interactions where OATHAuthKey::verifyToken is used.

Bryan Davis 36c523ab23 Add an api action to validate an OATH token
Add a new internal action=oathvalidate Action API module that can be
used to validate an OATH token collected from a user. Using the module
requires the 'oathauth-api-all' permission introduced in I4884f6e.

Attempts to call the action for a given user are rate limited to only
allow 10 failures per minute using the new 'badoath' key.

The check is primarily useful as an internal network service in an
environment where MediaWiki and other applications are sharing the same
backing authentication store (e.g. LDAP) and the non-MediaWiki
applications would like to respect the OATH protections enabled on the
MediaWiki install.

Complete usage in an LDAP shared auth environment would look something
like:
* Authenticate a user with the LDAP server via auth-bind
* Call action=query&meta=oath as a privileged user to check for OATH
  protection.
* If OATH is active for the account, prompt the user for their current
  OATH token.
* Call action=oathvalidate as a privileged user to validate the token.
* If validation succeeds, complete authentication.
* If validation fails, do not authenticate the user.

Bryan Davis 766e18bca1 Add a query meta api option to check for OATH
Add a new internal action=query&meta=oath Action API module that can be
used to check for OATH protection on a given user account. Using the
module requires a new 'oathauth-api-all' permission which is not granted
to any group by default. The permission is also added to the new
'oath' grant so that it can be used via OAuth and bot passwords.

Use of this API is security sensitive and should not be granted lightly.
Configuring a special 'oathauth' user group to grant the needed
'oathauth-api-all' permission is recommended.

This check is primarily useful as an internal network service in an
environment where MediaWiki and other applications are sharing the same
backing authentication store (e.g. LDAP) and the non-MediaWiki
applications would like to respect the OATH protections enabled on the
MediaWiki install.
