It is possible for getOriginalConnection() to return null at the end of
a call once the RIL has disconnected it.  Added null check to ensure
that isImsConnection() won't throw an NPE in this case.

The original code was the following, which is inherently NPE safe:
return getOriginalConnection() instanceof ImsPhoneConnection;

Currently, we do not make a copy of the extras Bundle when calling
Connection.setConnectionExtras. In rare cases, when multiple
setConnectionExtras events come in at the same time, they are posted
onto a concurrent Handler and the extras Bundle is cleared while being
copied in TelephonyConnection.updateExtras. This causes an
ArrayOutOfBoundsException and causes the Phone process to crash.

We now create a copy of the Bundle when we post it onto the concurrent
Handler to ensure that there is no simultaneous copy/clear operations
happening on the same extras Bundle.

Currently, any app can broadcast the intent to update the TTY mode. This
change updates the intents to protected broadcasts so that only system
can broadcast them. Otherwise, a SecurityException will be thown.

We may just be wanting to switch to auto select and scanning takes for ages !

If we want to scan, we can just tap on "Search networks".
