168de63a7a Switched back to a single LUT for 16-bit -> 32-bit pixel conversion 
This beats the previous 3-LUT version and even beats SSE on my system.

Test code:
---
int main( int argc, char *argv[] )
{
    SDL_Surface *orig = SDL_LoadPNG("testyuv.png");
    SDL_Surface *surf16 = SDL_ConvertSurface(orig, SDL_PIXELFORMAT_RGB565);
    SDL_Surface *surf32 = SDL_ConvertSurface(surf16, SDL_PIXELFORMAT_ARGB8888);

    Uint64 then = SDL_GetTicks();
    for (int i = 0; i < 100000; ++i) {
        SDL_BlitSurface(surf16, NULL, surf32, NULL);
    }
    Uint64 now = SDL_GetTicks();
    SDL_Log("Blit took %d ms\n", (int)(now - then));
    return 0;
}
---

Results on my system:
BlitNtoN: Blit took 34522 ms
Blit_RGB565_32 (3 LUT): Blit took 9316 ms
Blit_RGB565_32 (1 LUT): Blit took 5268 ms
Blit_RGB565_32_SSE41: Blit took 6399 ms

ce4af658ba events: Periodically poll tray events on *nix platforms 
Tray events on *nix platforms usually run over DBus, and the events subsequently aren't delivered via the window event queue. As a result, SDL_WaitEvent() won't unblock when tray events arrive, particularly if there is no currently active window.

Wake up periodically to poll when tray items are active to avoid blocking the delivery and processing of tray events.

8df057fafc iostream: Properly support the "x" mode for SDL_IOFromFile() 
The "x" mode for `fopen()` (open file only if it doesn't exist) used to
be a glibc-exclusive extension, but was later standardized in C11, and
is now also implemented as part of every other widely-used libc:

	* musl: https://git.musl-libc.org/cgit/musl/tree/src/stdio/__fmodeflags.c?id=0ccaf0572e9cccda2cced0f7ee659af4c1c6679a
	* Android Bionic / OpenBSD: 731631f300/libc/upstream-openbsd/lib/libc/stdio/flags.c (86)
	* Apple / FreeBSD: 63976b830a/stdio/FreeBSD/flags.c (L91-L92)

As a result, "x" has already been working on all our automatically
tested platforms that implement `SDL_IOFromFile()` via `fopen()`. So
all we'd be missing for proper support is a Windows implementation
using `CREATE_NEW`, and the documentation that this mode exists and is
intended to work.

ce1175724a win32: Don't overwrite a programmatically set window size with old data 
While in a modal loop, the size in WM_WINDOWPOSCHANGING/WM_WINDOWPOSCHANGED may only be updated if the window is being resized interactively. Set the SWP_NOSIZE flag if the size hasn't changed from the last move/size event, or a size set programmatically may end up being overwritten by old size data.

8fda4231cf wayland: Optimize the legacy key level fallback function 
When iterating over the keymap entries, a valid xkb state object has already been allocated, so use that instead of allocating/destroying a new state object for every lookup, which avoids a calloc/free operation inside libxkbcommon. Any state set by the level lookup function will be overwritten with valid state after keymap iteration has completed.

2c02e6f8bb wayland: Restore valid state information when building keymaps 
The spec doesn't guarantee that a modifier event won't arrive before a keymap event, or that it will always be sent after a keymap change if the modifiers and layout index haven't changed, so restore any valid state after allocation when building a new keymap.
