bb96320cc4 Make sure we always copy the data returned using SDL_GetStringRule 
This prevents race conditions where calling an API from one thread returns the data and it's freed by updates on another thread

2ba76dbe80 Simplified SDL_Surface 
SDL_Surface has been simplified and internal details are no longer in the public structure.

The `format` member of SDL_Surface is now an enumerated pixel format value. You can get the full details of the pixel format by calling `SDL_GetPixelFormatDetails(surface->format)`. You can get the palette associated with the surface by calling SDL_GetSurfacePalette(). You can get the clip rectangle by calling SDL_GetSurfaceClipRect().

SDL_PixelFormat has been renamed SDL_PixelFormatDetails and just describes the pixel format, it does not include a palette for indexed pixel types.

SDL_PixelFormatEnum has been renamed SDL_PixelFormat and is used instead of Uint32 for API functions that refer to pixel format by enumerated value.

SDL_MapRGB(), SDL_MapRGBA(), SDL_GetRGB(), and SDL_GetRGBA() take an optional palette parameter for indexed color lookups.

4d392bfc67 Fixed camera capture on iOS 
My phone captured 1920x1080 images even though the highest reported format was higher resolution, so I adjusted testcamera to be able to handle different sized images than expected.

e23257307e Introduce formal policy for APIs that return strings. 
This declares that any `const char *` returned from SDL is owned by SDL, and
promises to be valid _at least_ until the next time the event queue runs, or
SDL_Quit() is called, even if the thing that owns the string gets destroyed
or changed before then.

This is noted in the headers as "the SDL_GetStringRule", so this will both be
greppable to find a detailed explaination in docs/README-strings.md and
wikiheaders will automatically turn it into a link we can point at the
appropriate documentation.

Fixes #9902.

(and several FIXMEs, both known and yet-undocumented.)

pipewire provides a framerate fraction, we we just switch them.

2b9ac185cd camera: improve PipeWire version checks 
Remove the custom server version check. We can easily do this as part of
starting the hotplug loop. Check that we are at least running against a
1.0.0 server.

Log the compiled, linked, server and required versions.

Check that we are compiled and linked with the right version before using
the time symbol of a struct.
