Kohei TokunagaandPaolo Bonzini 8e72b0eb18 util: exclude mmap-alloc.c from compilation target on Emscripten
Emscripten does not support partial unmapping of mmapped memory
regions[1]. This limitation prevents correct implementation of qemu_ram_mmap
and qemu_ram_munmap, which rely on partial unmap behavior.

As a workaround, this commit excludes mmap-alloc.c from the Emscripten
build. Instead, for Emscripten build, this modifies qemu_anon_ram_alloc to
use qemu_memalign in place of qemu_ram_mmap, and disable memory backends
that rely on mmap, such as memory-backend-file and memory-backend-shm.

Binaries can register a QOM type to filter their machines

This can be used by example by main() -> machine_help_func()

Kohei TokunagaandPhilippe Mathieu-Daudé 16704598bf system/vl: Fix type conflict of GLib function pointers
On Emscripten, function pointer casts can result in runtime failures due to
strict function signature checks. This affects the use of g_list_sort and
g_slist_sort, which internally perform function pointer casts that are not
supported by Emscripten. To avoid these issues, g_list_sort_with_data and
g_slist_sort_with_data should be used instead, as they do not rely on
function pointer casting.

was depending on (TARGET_WORDS_BIGENDIAN). Later in commit

renamed as TARGET_BIG_ENDIAN but we didn't update the helper.
