Added ETWS primary message default message support
ETWS primary message does not contain messagy body. We used
to use hardcoded "ETWS" as the body, which is not easy for
end users to understand what happened. Added the built-in
default messages provided by Japanese government guideline
for earthquake, Tsunami, test, and other channels support to
enhance the user experience.
Test: manual

Phone refactor Phase II. Renamed PhoneBase to Phone.
Phone interface has been renamed to PhoneInternalInterface. For
outside world, Phone is now the only handle that should be used
for phone related classes (earlier there were Phone, PhoneBase,
GSMPhone, etc.). Some cleanup is still pending to make sure
technology specific phone is not used outside of telephony at all
(and even within telephony as much as possible).

[DS] Correct the access method for telephony system property
Revise the method to access telephony system property.
Add several PROPERTY_XXX_XXX_MSIM for MSIM type system properties. If
caller use the old one, it will be dispatched to new one and get by
default phone id.
Ex. PROPERTY_ICC_OPERATOR_NUMERIC

When phone changes update InBoundSmsHandlers and CellBroadcastHandlers.
Without this change for devices where the phone can change, for instance
on N5 with Sprint the phone will change from a GSMPhone to a CDMALTEPhone
and messages will not be sent to the appropriate handler.
For Sprint this was most readily seen when the voice mail notification
wasn't sent to the notification manager.

Refactor inbound (MT) SMS handling into new handler classes.
Moved all MT SMS handling to separate StateMachine classes, which
save all incoming PDUs in the SmsProvider "raw" table, previously
used only for storing PDUs of concatenated messages. Then we ACK the
message, before starting the ordered broadcast as usual. If a receiver
of the broadcast sets the status to failure, we ignore it, but in the
future we could provide a mechanism to redeliver the broadcast.
New classes are (without com.android.internal.telephony prefix):
- CellBroadcastHandler
- InboundSmsHandler
- InboundSmsTracker
- SmsBroadcastUndelivered
- WakeLockStateMachine
- cdma.CdmaInboundSmsHandler
- cdma.CdmaServiceCategoryProgramHandler
- gsm.GsmCellBroadcastHandler
- gsm.GsmInboundSmsHandler
This fixes a bug in the SMS dispatcher. Previously we delivered
incoming SM's as ordered broadcasts and then sent an acknowledgment
to the SMSC after the broadcast completed. It was possible for the
ordered broadcast to take over 20 seconds to complete, causing SMS
retransmissions because we didn't ACK quickly enough. Also, a
broadcast receiver could set the result code to failure (the AOSP
MMS app never does this), causing us to negatively acknowledge the
SMS, potentially leading to many retries and a backlog on the SMSC.
The reason for saving all PDUs in the raw table before ACKing is so
InboundSmsHandler can handle the failure case of a device crash or
power failure in between ACKing the message and the delivery of the
ordered broadcast to receivers. This is handled when the Phone class
starts, creating a new thread to run SmsBroadcastUndelivered.
This Runnable scans the raw table once, finding all complete
PDUs and sending IncomingSmsTrackers to the state machine to
broadcast them again to receivers. In the worst case, a message might
be added twice to the MMS inbox, but it won't be lost.
However, due to the current MMS app implementation, which immediately
acknowledges the ordered broadcast before starting a new Service to
process the message, there is a very short window of time when a
message could potentially be lost, if the MMS app or device crashed
after the ordered broadcast returns and the message is deleted from
the raw table, but before the MMS service has added the message to
its own tables. To fix this will probably require API changes.
Another improvement from this change: SmsBroadcastUndelivered also
deletes PDUs for incomplete multipart messages that are older than
30 days. We've never garbage collected this table in the past, so
it's possible for a phone to accumulate a number of old PDUs in the
raw table if not all components arrived successfully.
The wake lock handling is also improved in this version, as we now
acquire a wakelock when the state machine leaves the Idle state,
releasing it 3 seconds after returning to the idle state, instead
of the previous 5-second timeout. If a new SMS arrives while a
broadcast is being delivered, we add it to the raw table and ACK the
new PDU immediately, then send the InboundSmsTracker as a message to
handle when the previous broadcast completes.
In order to keep track of whether a PDU is in 3GPP or 3GPP2 format,
the destination port column of the raw table is extended with three
flags: 3GPP format, 3GPP2 format, and no destination port present.
Because the destination port is a 16-bit value in both 3GPP and
3GPP2, the upper bits of the destination port can be used for flags.
This saves us from having to modify the SMS provider to update the
DB version and to add extra columns to keep track of these flags.
