RSL_IE_OSMO_TEMP_OVP_ACCH_CAP and RSL_IE_OSMO_OSMUX_CID have been
defined for a while now, but are still not documented. Until someone
who knows them can document them properly, we need to at least
acknowledge their existence, and show the IEI code points that
have been allocated to them, so it is clear from the documentation
what IEI code points have already been allocated and where new
extensions are to be added.
