	    SamsungRIL: Fix data connection after pin unlock

	    If the user has PIN-locked his phone, data connectivity will not
	    work because the RIL sends APPSTATE_UNKNOWN and does not update
	    it to APPSTATE_READY. We inject the state update if there's a
	    signal change.

	    SamsungRIL: cleanup

	    Removed unneeded states and forward them to RIL. In ics, this had
	    the side-effect of allowing STK to work due to the Samsung STK
	    implementation already in place

	    cherry-picked from ics

	    stk functionality for SamsungRIL

	    * Implemented SMS based SIM application functionality
	    * PatchSet 3: Added fix so unknown unsolicited response are sent to super class
	    * PatchSet 4: Removed "import android.content.resources" - not needed any more
	    * PatchSet 5: processUnsolicited cleanup, using super class standard states where possible
	    * Patchset 6: Rebased

	    samsung ril: add UNSOL_AM implementation

	    * The Samsung RIL will sometimes send up an UNSOL_AM
	    request which is to be handled by the "am" service.
	    (For example when the RIL resets)

	    Fix for Signal bars on Samsung devices

	    Sometimes the CDMA ecio value is sent as a negative integer where we would expect a positive.
	    This causes SignalStrength.java to mark ecio as -160 (Unknown_Signal_Strength) and making signal bar
	    s clear out.
	    This "fix" checks the ecio value and takes it absolute value if it is negative.

	    Confirmed working on SCH-I500 and SPH-D710

	    telephony: SamsungRIL cleanup

	    == RIL ==
	    * remove unused "found" boolean in processSolicited
	    * make requestToString/repsonseToString append the request
	      ID on unknown requests.

	    == Samsung RIL ==
	    * add CM copyright header to file
	    * SAMSUNG_UNKNOWN_MAGIC_REQUEST_3 is actually UNSOL_AM
	    * add DIAL_EMERGENCY to a SamsungRIL::requestToString
	    * add DIAL_EMERGENCY response to processSolicited
	    * move emergency dialing into dialEmergencyCall()
	    * dialEmergencyCall() also ditches UUS info like on stock.
	    * cleanup and improve readibility of responseCallList()
	    * move isVideo before isVoicePrivacy, as it is in stock:
	        ref "stock" code: http://pastebin.com/WePMyXDi
	        ref "stock" order: isMpty then isMT then als then isVoice then isVideo

	    SamsungRIL: Fixes for CDMA data reconnection failures due to stale pppd

	    Occasionally the CDMA data connection fails to reconnect after various
	    radio events, which is fixed neither by toggling mobile data nor airplane
	    mode, but only by a reboot.  One known cause of this problem is that the
	    pppd_cdma service is occasionally left running after the radio event, which
	    causes all subsequent "setup data call" operations to fail.  These two
	    fixes address the stale pppd_cdma service issue:

	    - Move the pppd_cdma service shutdown (set ril.cdma.data_state=0) from the
	      "deactivate data call" response to its request.  This avoids the issue
	      where the response never comes (radio crash?), and thus, the service is
	      never stopped.

	    - Force pppd_cdma service shutdown on a "setup data call" failure.  This
	      allows subsequent setup attempts to succeed in the event that the
	      "deactivate" request was never made (unexpected radio poweroff).

	    Add more CDMA SamsungRIL fixes.

	    Adds a collection of CDMA device fixes to SamsungRIL.  They include:

	    - Overriding ERROR_UNSPECIFIED fail cause with NORMAL_CLEARING, to prevent
	      far-end hangups from displaying the "Call Lost" dialog.

	    - Adding, and ignoring the RIL_UNSOL_GPS_NOTI request, which is also
	      ignored in the TW RIL, to keep the radio log clean of exceptions when the
	      GPS is active.

	    - Workaround for Samsung CDMA "ring of death" bug.  See source comments for
	      details on this problem.

	    Fix support for CDMA devices in SamsungRIL.

	    These fixes are ported from jt1134's fascinatemtd patches and CM7.  For
	    CM9, the fixes are applied to SamsungRIL directly instead of elsewhere in
	    the telephony framework.  They include:

	    - Signal strength reporting: pass raw integer values.
	    - Voice registration: convert base station values from hex to dec.
	    - Data call setup/deactivate: start/stop pppd_cdma service and pull network
	      parameters from pppd ip-up script.
	    - CDMA subscription: add missing PRL version from system properties.

	    Changes from CM7:

	    Note use of "ril.cdma.data_state" property instead of
	    "ril.cdma.data_ready".  This property has three states:

	    - Disconnect(ed): ril.cdma.data_state=0: stop pppd_cdma service.
	    - Connecting:     ril.cdma.data_state=1: (re)start pppd_cdma.
	    - Connected:      ril.cdma.data_state=2: pppd_cdma has responded.

	    The disconnect (0) and connecting (1) states are set by SamsungRIL on the
	    deactivation and setup, respectively, of a data call.  Prior to setting the
	    connecting (1) state, SamsungRIL sets the "net.cdma.datalinkinterface" for
	    pppd_runner's use.

	    After setting to the connecting (1) state, SamsungRIL waits for pppd_cdma
	    to respond by (itself) setting the connected (2) state.  This should be
	    done at the end of a /system/etc/ppp/ip-up script, after that script sets
	    the following interface values, which SamsungRIL uses to complete the data
	    call state:

	    - net.cdma.ppp.interface: $IFNAME (typically "ppp0")
	    - net.$IFNAME.local-ip:   pppd's local IPv4 address
	    - net.$IFNAME.remote-ip:  pppd's remote IPv4 address
	    - net.$IFNAME.dns1:       pppd's primary DNS address
	    - net.$IFNAME.dns2:       pppd's secondary DNS address
