Send out a configuration change when screen size changes due to expanded
desktop.

This kills the status/nav bar hide/show animation, but it's required by
some apps to recalculate their content correctly.

Frameworks: take  mPieScale into account to calculate estimated PIE width

if scaled size of the PIE is over or under the default size
the pie was either no using the whole screen space or
it was cutted off. To solve this take scale value
into account when calculating estimated width

Framworks: disable observer and receiver if PIE is disabled

on high end devices that is maybe not needed. But there
is in general no need to enable the obeserver/receiver
when PIE is disabled (or expanded mode is off)
This change destroy and disables the PIE in most parts
when it is disabled. + a small doubel register
correction
