hook_openid('request', ...) renamed hook_openid_request_alter()

• The hook_openid('request', ...) is now called hook_openid_request_alter().
• The new hook_openid_request_alter() takes $service array as an argument.
• hook_openid_response($response, $account) is now invoked for all responses received even if there is no $account.

API Changes

• hook_openid($op, $request) is converted to hook_openid_request_alter(&$request, $service).

Impact on contributed modules

• Use hook_openid_request_alter(&$request, $service) instead of hook_openid('request', ...).
• Other modules can act on OpenID login even if there is no $account thanks to hook_openid_response($response, $account).
