	    telephony: let us write just the aid on getIMSIForApp

	    This implements a new RIL compatibility feature, "writeaidonly", that
	    lets us write just the aid, without the preceding 1. This is needed to
	    be able to read the IMSI correctly on some Motorola RILs

	    ril: avoid sending null aid string in getIMSI

	    A change to how getIMSI works in JB causes null aid strings
	    to be sent.  The result for RILs older than v7 is a corrupt
	    ril response in SIMRecords::fetchSimRecords.  This corruption
	    ends up setting mImsi to null (in SIMRecords) and that causes
	    havoc w/ 3g/4g data connections.

	    This patch avoids sending null aid strings and has fixed
	    data connection issues on several Motorola devices.

	    This new patch is implemented as an opt-in old ril feature

	    RIL: skip broken RIL_UNSOL_DATA_CALL_LIST_CHANGED

	    Some old RILs might produce events with type 'IP' containing the remote IP
	    address, normally 10.64.64.64. These events mismatch with the previously
	    generated ones and cause the system to take the connection down, even if
	    it was up and working correctly.

	    Add skipbrokendatacall to ro.telephony.ril.v3 to enable the workaround.

	    RIL: Add compatibility with qcom's DSDS

	    Devices with radio libraries built against a DSDS-enabled qualcomm
	    BSP (anything in the last 4 or 5 months, apparently) have a slight
	    incompatibility in the RIL protocol: it expects the first 4 bytes
	    of the datastream to be the slot's identification (even if the
	    device isn't dual-SIM). Absence of those 4 bytes will make the
	    connection hang.
