Remove the one commit (as far as I can tell) by soreau that added nontrivial material still in the tree

    EGL: Properly set parent window.
    
    In X with EGL and WX frontend enabled, running the emulator created
    two windows. This was because the parent window was set incorrectly.

    Fix broken build when using SDL from Externals.
    
    The problem here was the logic that detects SDL in the main CMakeLists.txt
    is not the same as it is in DolphinWX/CmakeLists.txt to set libraries. When
    using SDL from Externals it failed at link time because -lSDL was never set.
    This fixes the problem by using the same condition logic to set the libs
    as used when detecting SDL in the first place.

--> pretty trivial, but was already rewritten anyway

    Use correct linker flags for SDL.

    Re-add hack to use SDL/SDL.h ifndef _WIN32.
    
    The correct convention is to use #include SDL.h in all cases but we have to
    do this so Externals/SDL builds, which isn't in the best shape.

--> no longer present

    Add periodic effects for haptic devices.
    
    This adds support for drivers supporting sine, square and triangle
    periodic haptic effects. This allows rumble to work on devices/drivers
    supporting these effects, such as an xbox controller using the xpad
    driver under Linux.

--> code removed; if you feel like fixing the xpad driver on Linux, don't read the commit...

    Add SDL2 support to build system.
    
    Dolphin code already builds against SDL2 but the build system never
    checks for SDL2, which is the what latest SDL is called now. SDL2
    replaces SDL 1.3. This allows Dolphin to be build against SDL2, which
    activates certain new features such as the haptic interface.

--> trivial except for FindSDL2.cmake, which was not written by soreau
