Introduce maxSdkVersion for <uses-permission>

This way an application can automatically sunset its permission requests
when running on later versions of the OS where those permissions are no
longer relevant, but may be alarming to the user.  A canonical example
is WRITE_EXTERNAL_STORAGE, which as of KLP becomes unnecessary for an app
to use the external storage volume solely for its own large-data needs,
without the need for actual file-system sharing among multiple apps.
