Since the StatusBarPolicy is run in the System Process and shouldn't therefore call into
the Telephony process we decided to make sure all the needed info was passed along with the
original notifications.
bug: 2173053
HSDPA: High-Speed Downlink Packet Access
HSUPA: High-Speend Uplink Packet Access
HSPA: High-Speed Packet Access
Add support for HSDPA/HSUPA/HSPA:
1) extend TelephonyManager.NETWORK_TYPE for HSDPA/HSUPA/HSPA
2) extend ServiceState.RADIO_TECHNOLOGY for HSDPA/HSUPA/HSPA
3) set radioTechnology into ServiceState in GsmServiceStateTracker
4) change the implementation of TelephonyManager.getNetworkType to
solve the competition timing issue between the time of setting
system property and the time of receiving notification through
PhoneStateListener
4.1) add a getNetworkType interface in ITelephony.aidl
5) add icons resources for HSDPA/HSUPA/HSPA
6) make use of HSDPA/HSUPA/HSPA icons in StatusBarPolicy
