(DO NOT MERGE) Fix pub issue #58043: Copy crash in Android 4.3...

...when clipboard listener attached

We need to clear the calling identity before dispatching change
notifications.  Also make this more robust, so that in the face
of any failure we will clean up the broadcast state.

Integrated from master.

Allow the user to block notifications for foreground services.

Stepping carefully around the fix in change Idc788527, we
perform security (and AppOps, and therefore user block)
checks against the uid passed to enqueueNotificationInternal
rather than the Binder caller.

Add version identifier to app ops.

All old versions drop their modes except for the notification op
(which is the only one there is currently a user-visible control for).

Fix issue #10226007: Reset apps restores most of the changed settings...

...to original but not all modified ones

Very stupid mistakes in messing up the iteration when pruning op
entries.

Use hostname verifier directly instead of instance DO NOT MERGE

Instead of local instance of the default HostnameVerifier, use it
directly from HttpsURLConnection. This avoids class preloading creating
an instance of it before it's necessary.
