Refactored precise data connection state
Instead of triggering the data connection state changed
event from outside, now the event is triggering from
DataConnection. Whenever detecting data connection
state changes, the event will be triggered. This significantly
reduced the unnecessary redundant events sent to telephony registry,
even though it has a duplicate detection mechanism.
This are also two behavioral changes.
1. Previously if a data connection supports multiple APN types,
there will be multiple data connection state changed event for
each APN type. Now there is only one. The listener should use
PreciseDataConnectionState.getApnSetting().getApnTypeBitmask()
to check which APN types this data connection supports.
2. If setup data call fails before a data connection instance
can be created, there won't be any event with fail cause.
