Annotation callout closes automatically when changing the viewport

[incanus]

Android now does this.

Complicated by the fact that SMCalloutView doesn't support a move API, just a placement/initial layout. On raster we used to use this repeatedly during viewport changes to sync up, but it became non-performant as of last check.

Also leave it open when the user location changes: #2618.

I have the same problem. Auto-closing of the annotation callouts after the map was moved (by app or manually by user interaction) seems to be a bad user experience. Moreover when you have a click event (button) within the callout bubble and user did a little bit move the finger while clicking, the pop-up disappears and the click event was not triggered.

As a workaround we tried a re-select of last selected annotation after a map move but that does not work really good.

As demonstrated by #1582, all we need to do is set self.calloutViewForSelectedAnnotation.frame, potentially inside a UIView animation block, instead of closing the callout view as we do now.

Fixed in #6676 on the v3.4.0 release branch.
