Dav: added error logging. Previously, when request body was not available or was previously read in memory rather than a file, client received HTTP 500 error, but no explanation was logged in error log. This could happen, for example, if request body was read or discarded prior to error_page redirect, or if mirroring was enabled along with dav.
