Showimage: Wait for loader threads on exit.

* Uses find_thread to wait for loader threads.
(better solutions are welcome)
* As suggested by Axel the cache isn't static anymore.
* Fixes 8902.

Remove remaining unnecessary 'volatile' qualifiers

* Removed the obsolescent [B]Reference[able] API and replaced the remaining
uses. Fixes the gcc 2 acpi build.
* Renamed WeakReferenceable::{Add,Remove}Reference() to
{Acquire,Release}Reference() for consistency.

* Removed the "shrink to window" option. Instead, there is now a "Fit to window"
menu item that just does that. Additionally, the image is always fit to the
window size when first shown, or if the full screen mode switches.
That also fixes #6765, and #6810.
* The ImageCache now also passes a referenced BitmapOwner object, and bitmaps
are now actually freed when it's allowed to.
* Pressing the zoom button will cause ShowImage to enter full screen again. For
some reason this has been removed as part of r19540.
* The progress window is now visible again, although not that often, as you will
only see it for images that were not in the queue already. The window is now
known to the ShowImageWindow instead of the ShowImageView.
* Moved most constants out of ShowImageConstants.h to where they belong.
* Dropping an image now opens it in another window.
* Removed EntryMenuItem as it's no longer used anywhere.
* Minor other cleanup.

* Implemented preloading of the images around he current one; always two in the
direction of the current navigation, and one in the opposite direction.

* The ImageFileNavigator is now only for navigation, it doesn't load any images
anymore.
* Moved the new ImageCache into its own source file.
* The cache is now used within ShowImage. There is no read-ahead caching being
done yet, though, but you can quickly return to previous images, and you can
also skip images faster than before.
* Improved separation between the ShowImageStatusView and the rest;
ShowImageWindow no longer has a getter for the image view.
* The status view is now using the private BDirMenu which implements enhancement
ticket #6778.
* Made a few more methods private/protected in ShowImageWindow.
* Fixed bug #6797.
* The bitmap is currently only owned by the ImageCache, but we need to have a
separate referenceable object owning it. Added a TODO comment for this.
* The ProgressWindow is currently not being used anymore, added a TODO comment
for this as well.
