Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

x11: Make a separate unmapped window to own clipboard selections. Now the clipboard isn't lost if you destroy a specific SDL_Window, as it works on other platforms. You will still lose the clipboard data on SDL_Quit() or process termination, but that's X11 for you; run a Clipboard Manager daemon. Fixes Bugzilla #3222. Fixes Bugzilla #3718.

x11: Deal with window borders better. - Cache the _NET_FRAME_EXTENTS data locally, so we don't have to query the X server for them (instead, we update our cached data when PropertyNotify events alert us to a change). - Use our cached extents for X11_GetWindowBordersSize(), so it's a fast call. - Window position was meant to refer to the client area, not the window decorations, so adjust appropriately when getting/setting the position.
