    Improve scrolling cache

    Scrolling cache helps make short scrolls/flings smooth but will
    cause stutter when long flings are made. This patch disables
    scrolling cache when long flings are made.

    This patch also fixes a related bug where scrolling cache will
    not be enabled properly when transitioning from flinging to scrolling.

Turn off carrier provisioning by default to allow tethering

Whether or not to use carrier provisioning is a setting hidden to the
end user that is currently not set. Unfortunately, on some carriers that
may result in it being set to yes, or effectively set to yes, without
other accompanying changes that must occur, such as setting a tethering
apn and possibly having a carrier provisioning app, resulting in hitting
a paywall when a tethering plan exists, or, worse having nothing happen
at all when you try to tether since the data doesn't have an apn set.

Frameworks: Add per app controls for LP keyguard notifications (1/2)

Nice done by google but the UX is a problem especially for ppl who are using a lot apps and just want
to see from important apps the notifications on the lockscreen.

This commit adds the ability to

- enable/disable per app the keyguard notification at all
- enable/disable per app ongoing notifications on the keyguard

We handle this over the app policy conf file like the other per app notification options.
