framework: Allow specifying max wallpaper width

For some devices with very high-res screen (1920x1200), the wallpaper
width suggested by the launcher may be too large for the GPU and so
we need to limit it. (2048 for the above mentioned screen)

We don't need to limit the height since that's the height of the
screen.

Revert "Auto-close if you swipe away the last notification."

This reverts commit 8cc36e572876f3bb9197f0109db3042466e5f917.

It didn't work as advertised anyway: It only worked if there are no
persistent notifications, and it also closes the notification area if
the notification is closed by the app itself.

Fixes for clang:
PackageInfo is a class, not a struct.
String16 is contained in the android namespace. Do not namespace prefix it
within the android namespace.
Explicitly specify which std classes are necessary to prevent ambiguous
type errors. (map, set)

Return the actual interpolator of the ViewPropertyAnimator

The implementation of getInterpolator() was always returning null
(probably a quick copy-paste from the default Animator implementation).
This patch fixes the problem by returning the interpolator set by
setInterpolator(TimeInterpolator) or the default one if none has been
set yet.

This patch also avoid creating multiple instances of ValueAnimator in
order to retrieve some default values.

Don't include flags in configuration change if their value hasn't changed.

This makes the check in updateFrom() match the logic in diff().

Prefer artist over album artist.

E.g. when playing a compilation title, one very likely wants to see the real
artist instead of 'Various artists'.
