Fix no ringtone and notification sound after MediaScan

When ringtone and notification is not customized, the customized
ringtone/notification file name will be null. It will lead to
NullPointer exception when call doesPathHaveFilename().
Fix it by adding customize feature control and empty check.

Telephony: Add new api isMmsDataConnectivityPossible.

- Add a new telephony manager api to get possiblity of mms PDP.
- Its a preemptive API, if app is made aware of that MMS PDP is not possible
  then app can preempt the transaction. It would help in avoiding
  unnecessary PS ATTACH or DDS switches in msim devices.

WiFi : Fix to DHCP to static IP configuration problem

WiFiStateMachine shall update the IP address configuration to
the kernel through NetworkManagementService.This notification
from the kernel is again sent to the connectivity service
through the NetLinkStateTracker and WiFiStateMachine.
Thus ,if the interface is down during this IP address
reconfiguration (for the case of DHCP to Static IP configuration),
Connectivity service shall be notified with old IP address ,NULL(0)
IP address(signifying interface down) and the latest IP address.
This notification was done by updating the IP address using a local
variable , and hence the second notification on the interface down
is over ridden by the last notification , resulting in missed
interface down notification to the connectivity service.This
resulted in failed data connection when IP address is changed from
DHCP to IP on the fly.
Hence ,this gerrit enhances the design and also pass the updated
IP address to the connectivity service.

Start MountService before performBootDexOpt

This change is to start Mountservice before starting
performBootDexOpt, as in one case, in performBootDexOpt
when system upgrade happens, StorageManager will be started to
get the low threshold of DataDir. But, at this point, as
Mountservice is still not up, StorageManager will end up
having a null object of Mountservice.
