Polish the shared image provider

When the new shared memory image provider was added, some of the
issues identified during review were postponed to be fixed during
stabilization phase. This commit deals with
- Replace the kludge for registering plugin version
- Add autotest
- Place plugin in labs
- Use QT_CONFIG instead of QT_NO_xxx
- Use the new extended image provider api, in order to use the
  scaled-size calculation from Quick
