Base header

[oddbookworm]

Another precursor PR to #3477
The reason I want to remove so much static linkage is because you can't test functions that aren't visible to you (not even worth putting those declarations in the header, since anyone that includes the header would need to provide their own implementation to call them).

[gresm]

You could also do in base_test.c:

#include "base.c"

[...]

But that'll make building tests messy...

[oddbookworm]

You could also do in base_test.c:

#include "base.c"

Absolutely not

That begs for linker problems that would be a pain to solve, and ultimately, having a header with all the declarations is just cleaner IMO. Including a source file is just plain nasty

there are problems that could be solved i thing by simply merging static and base ( ie when wasm loading pygame_base static could be set to pygame.base by pygame/__init__.py

[pmp-p]

last commit won't do it : wasm at runtime says that pgExc_SDLError needs to be globally exported for dynamic loading.

[pmp-p]

That PR (minus last commit) would unlock further work on meson wasm build. it is already viable for non cython files( _sdl2 )

[pmp-p]

mixer.c should only use MODINIT_DEFINE(mixer)

pygame-ce/src_c/mixer.c

Line 2052 in 2036f44

#if BUILD_STATIC

because now sdl2 mixer init has been renamed

I am approving all the non-wasm/non-static changes of this PR, I trust pmp-p has reviewed the wasm/static specific bits.
