Modified samsung-ril to work on Nexus S.

Currently, the following is working:
* (automatic) network registration (clean and stable)
* SMS (no clean queue engine and no support for multiple message SMS)
* SIM I/O
* Other minor stuff

And the following is left to do:
* DATA (3G)
* airplane to normal power mode
* calls (including audio routing)
* RFS messages handling (mostly to be done at IPC level)
* Other minor stuff
