Feature/linux gtk removal (#1225)

* GTK remnants removal

Remove old GTK code and wire up some missing fltk logic in llfilepicker
This will leave linux_crash_logger as an empy stub which could be used as a skeleton in case crash logging gets implemented.
Otherwise linux_crash_logger and what is left of it in some cmake files can be deleted.

* Update SDL2 to latest version.

This revealed openal has also a dependebcy on sndio. Consequently the dependency was moved to OPENMAL.cmake and canot be dropped.

* Handle missing filetypes:
FFSAVE_GLTF,FFLOAD_GLTF, FFLOAD_MATERIAL, FFLOAD_MATERIAL_TEXTURE
