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).

Lockscreen Notifications: use the correct member visilibility access modifiers

using private modifier on outter class members requires the compiler to generate
additional accessor methods when access is requested by inner classes. This
is effectively doing the opposite of inlining code and can slow things down
