Fix theme provider crashing for non-primary user.

PackageManagerService's context is for user 0, so if the theme provider
for other users was invoking the getInstalledThemePackages() method, the
themes provider crashed as it doesn't have the INTERACT_ACROSS_USERS
permission.
Fix that (and simplify code) by making getInstalledThemePackages()
return the installed themes for the current user, which was probably the
intent anyway.

Add SMS Middleware layer.

Add fix so ordered broadcasts are delivered to system
apps first in the event of a tie. This works around
the issue where terrible apps steal SMS notifications
from the broadcast queue to simply prevent notifications
that could otherwise be removed by a toggle.
