cbf9072e45 SDL: Fix leaks related to graphics modes 
supportedGraphicsModes() now returns to OSystem_SDL a pointer to a deep copy of
surfacesdl's internal graphics mode array. Therefore each can free its
own copy without interfering with the other's.

ab8dd417a9 SDL: Use enableSource() when scaling to the overlay 
This fixes an issue where the screen would have little or no changes
and nothing would be drawn to the overlay.

853d545284 SDL: Make sure normal scaler plugin is initialized 
If a game and graphics mode were chosen from the command line, the normal
plugin might not have been loaded and it would crash upon being used to
scale the cursor. Now the normal plugin is initialized with the first
plugin to be initialized.

a41cd52bbf SDL: Use a simple blit function instead of normal scaler plugin 
For places where a blit is needed and no scaling is required, this
function is used instead.

4c967c5fbc GRAPHICS,SDL: Revision to scaler API 
oldSrcScale() is now unified with scale(). Use enableSource(bool enable)
to switch functionality. Partial screen updates are also posible because
of this.

initialize() had its prototype changes although it is functionally the
same.

setSource() no longer has a type parameter, removing support for
multiple source surfaces. They weren't useful anyway.

useOldSrc() was renamed to useOldSource() to conform to the names of
other functions.

c5c5662330 GRAPHICS,SDL: Change oldSrcScale api 
More bookkeeping is kept in common scaler code instead of the backend.
Plugins inheriting SourceScaler will have this functionality.

TODO: Some new functions may still be able to be combined to simplify
the API.

8baa92a190 SDL: Fix overlay while using oldSrcScale 
The _destbuffer was overwriting _hwscreen even when the overlay was
visible.

3b408c2d87 SDL: Use an extra buffer for oldSrcScale so it is not confused by AR 
If the two source images match, the scaler assumes there is not update
and does not draw to the surface. However, AR correction depends on a
redraw, so the scaler always writes to _destbuffer which is then copied
to _hwscreen to be AR corrected.
