Framework changes to support HSDPA/HSUPA/HSPA

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
