    Further abstraction.

    This change introduces the ApacheBackend interface for backends that
    depend on Apache authentication and session management. There are no
    longer references to specific backends in OC_User.

    Amends the login link

    When using a Shibboleth login, clicking logout displays a message to the
    user instead of ending the session.

    Separate the authentication methods

    SABRE authentication and base authentication have slightly different
    workings right now. They should be refactored into a common method
    later, but time pressure requires us to reinvent the wheel slightly.

    Authenicate calls to WebDAV against Shibboleth.

    When using WebDAV, the OC_Connector_Sabre_Auth::authenticate method is
    normally called without trying the Shibboleth authentication... thus the
    session is not established.

    The method now tries Shib authentication, setting up a session if the
    user has already authenticated.

    Add a method for attempting shibboleth login.

    If the PHP_AUTH_USER and EPPN environment variables are set, attempt a
    Shibboleth (passwordless) login.

Move aborted upload detection into it's own sabedav plugin 

adding privilege check on move and rename operations

cURL does not honour default_socket_timeout

SabreDAV uses cURL for the requests and as this does not honour
default_socket_timeout, setting it is useless and confusing as
people will expect the request to timeout faster than it actually
will do.

One has to use
 curl_setopt($curl, CURLOPT_TIMEOUT, x)
or
 curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, x)
but there is currently no way to make SabreDAV pass this to cURL.
