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().

wayland: Add support for xdg-shell protocol (unstable v6). This is meant to be the desktop-enhanced version of wl_shell. Right now we just match what the existing wl_shell code does, but there are other areas of functionality available to us now, that we can fill in later. This uses the "unstable" API, since this is what ships in Ubuntu 17.10 (as part of Wayland 1.10), but Wayland 1.12 promotes this to stable with extremely minor changes. We will add support for the stable version when it makes sense to do so.

wayland: Add support for relative mouse mode, by Jonas ?dahl <jadahl@gmail.com> Generate the C protocol files from the protocol XML files installed by wayland-protocols, and use them to implement support for relative pointer motions and pointer locking. Note that at the time, the protocol is unstable and may change in the future. Any future breaking changes will, however, fail gracefully and result in no regressions compared to before this patch.

wayland: fix resizing and fullscreen toggling For starters, we need to correctly respond to 0,0 configure after unsetting fullscreen. Also, turns out that there should be no drawing calls at all in between eglSwapBuffers and wl_egl_window_resize, as otherwise EGL can already allocate a wrongly sized buffer for a next frame, so handle those together.

Fixed bug 3063 - Wayland: SDL resizes EGL surface to 0x0. x414e54 Wayland will sometimes send empty resize events (0 width and 0 height) to the client. I have not worked out the exact conditions a client would receive these but I can assume it might be if the window is offscreen or not mapped yet. This causes issues with some SDL clients as they receive the 0x0 event and unexpected resize event or might not request to resize back to the correct size. As per the wl_shell Wayland spec configure events are only a suggestion and the client is free to ignore or pick a different size (this is how min/max and fixed aspect ratio is supped to be implemented). A patch is attached but is just the first iteration and I will fix any issues such as checking for FULLSCREEN/MAXIMIZED or RESIZABLE flags unless someone else fixes this first. I have update to take into account non resizable and fullscreen windows. Also adding in maximize/restore and title functions for Wayland.
