Squash all 4.2.2 changes into one

Assume LTE location info is base 10 but allow 16 or 8.

Previously it was base 16 but somewhere along the line it changed
to base 10. The code is now changed to use the decode method which
assumes base 10 but also accepts base 16 (prefix 0x, 0X, #) or
base 8 (prefix 0).

simcard: With Kazakh Beeline SIM card, there isn't STK menu

IccFileHandler.java is modified to fix an erroneous EF_IMG file path
information. The other is CommandParamsFactory.java file, which is modified
to ignore the result of reading EF_IMG file.

This Beeline SIM card returned an error status word when the mobile device
accessed the EF_IMG file in this SIM card.
(I think this Beeline SIM card does not support EF_IMG file.)
As a result, This error result stoped processing the setup menu proactive
command, and there was no STK menu.

So, I modified the CommandParamsFactory.java file to ignore the result of
EF_IMG file read operation.
After applying this modification,  The STK menu was successfully displayed.
(This issue was resolved by these modified files.)

I think there will be no critical problem even if the EF_IMG(Icon image) file
is ignored.

Set audio mode after accepting the call

Set the audio mode to incall immediately after accepting the call and not wait
till call is reported as ACTIVE by RIL. This is done to speed up time taken for audio
to set up the voice path

Turn auto attach on/off when we attach/detach.

Some network operators will detach after a timeout period, isDataAllowed()
will not allow a data connection because mAutoAttachOnCreation is false
and gprsState is not STATE_IN_SERVICE.  This change toggles
mAutoAttachOnCreation based on attach/detach events and data will be
allowed if gprsState == STATE_IN_SERVICE or mAutoAttachOnCreation.
