Telephony API extension v2

Added new AndroidManifest permission:

android.permission.READ_PRECISE_PHONE_STATE

Added the following PhoneStateListeners and corresponding broadcast intents:

onPreciseCallStateChanged(PreciseCallState callState);
onPreciseDataConnectionStateChanged(PreciseDataConnectionState dataConnectionState);

broadcastPreciseCallStateChanged(int ringingCallState, int foregroundCallState, int backgroundCallState,
	int disconnectCause, int preciseDisconnectCause)
broadcastPreciseDataConnectionStateChanged(int state, int networkType, String apnType, String apn,
	String reason, LinkProperties linkProperties, String failCause)

Added TelephonyManager intent actions with their extras and constants:

public static final String ACTION_PRECISE_CALL_STATE_CHANGED = "android.intent.action.PRECISE_CALL_STATE";
public static final String ACTION_PRECISE_DATA_CONNECTION_STATE_CHANGED = "android.intent.action.PRECISE_DATA_CONNECTION_STATE_CHANGED";

public static final int PRECISE_CALL_STATE_*

Moved public static final int DISCONNECT_CAUSE_* from PreciseCallState.java to a new class DisconnectCause.java

Moved public static final int PRECISE_DISCONNECT_CAUSE_* from PreciseCallState.java to a new class PreciseDisconnectCause.java
