Add internal fileid to webdav response

Handle errors on memcached level

Introduce a new property "oc:fileid" to return the internal file id.

This is because the original "oc:id" property is a compound and it is
not possible to extract the real id without knowing the instance id. The
instance id is not available to external clients.
