HACK: cutils: restore record_stream temporarily

Restore the record_stream code in cutils that was removed
in e00a12bf as part of cutils
cleanup.

Unfortunately, there are some prebuilt vendor libs that rely on
this functionality that we cannot currently rebuild.

Remove at the earliest possible convenience once the vendor libs
have been fixed.
