We keep merging AOSP hardware/ril whenever we claim that the new version of Gonk is supported.  Duplicate lines somewhere means it might not cause conflicts at merging, which follows we may forget to apply corresponding changes to these duplicated lines as well.  AOSP Jellybean adds two additional __RIL_LTE_SignalStrength_v8__ and __RIL_SignalStrength_v8__ types.  Although there is no changes made to `requestSignalStrength` in JellyBean and even in KitKat, that still raises a concern in my mind that I have to check these duplicated line in next merge as well.  I'd really want to avoid that.  Please add a new function that parses __+CSQ__ results and share it with `requestSignalStrength`.
