Tethering: Enable NAT only when tether and upstream ifaces are different.

When enabling WIFI hostspot, chooseUpStreamInterface will choose WIFI
interface as it is still up. It will result in both tethered and upsteam
interfaces are same one. netd will reject this command and tethering
will fail this time.

This fix will not send NAT command to netd when it found these two
interfaces are same one. Later when the real upstream interface is
brought up by ConnetivityService, Tethering.java will continue the NAT
procedure.

Telephony: Avoid Infinite loop problem in Tethering

1. Whenever data is enabled we will try to establish the tethered
call (USB tethering enabled case) for 5 fixed number of retries.
After reaching maximum number of retries we are turning off the
upstream connection. whenever the CONNECTIVTY_ACTION received
(because of USB cable disconnected and then connected case or
some changes), it can try to bring up the dun/hipri PDP again.

2. There is no retry in case of data disabled case.

base: Add P2P interface "p2p0" to tethering support list

Dnsmasq is running as singleton pattern, P2P GO start DHCP server fail
if dnsmasq has been started by USB tethering. Tethering management
feature in Tethering.java just support soft AP and USB tethering. Add
P2P interface "p2p0" to tethering support list.

Tether: fix the retry issue in Tethering

Since StartUsingNetworkFeature will always return success, it's
not a good place to set retry. With this modification, the retry
will work.

frameworks: fix setting default ringtone for multi sim

The defualt value for the ringtone expects a "_" between the setting and
the requested sim subscription. This was not being respected in the
mediascanner when it set the default ringtones, resulting in the setting
value being "ringtone2" instead of "ringtone_2".

linearlayout: fix measurement of childrens when parent and childrens have exactly the same pixels

When children measure exactly the same width/height than the parent, any child with
width/height == 0 and with weight > 0 must be reset. Otherwise, the view will retains
the same width/height between measurements calls (that is not valid if the view changed
its orientation).

This explain the bug in CYAN-5471 when in hpdi devices the spacer view has the same
width after rotate from landscape to portrait when language is german and date beewteen
September 10-30. Steps to repro in i9100 (hdpi):

1.- Set language to german and date to September, 10.
2.- First run, the expanded bar has the same width that its children (480px the current
screen size), but spacer has 0px (because it isn't being measured by linearlayout).
3.- Rotate to landscape, spacer gains space and all buttons are displayed correctly.
4.- Rotate to portrait, spacer has the same width that in step 3, because it isn't measured
again and delta == 0;

This patch forces this views to be re-measured to 0 to match the current delta (the views doesn't
need to be expanded or shrinked).

SystemUI: Fix crash during notification/theme change

Fixes crashing that could occur when a notification is created
during a theme change. Entries were attempting to be added
to views which did not have a layout pass yet, causing it to fail.

When a theme change occurs, the fix is to halt the ticker and command queue
until a layout occurs.
