[PATCH v8 0/5] MR7848: server: Use events as a sync for several objects.

[Rémi Bernon (＠rbernon)]

Instead of https://gitlab.winehq.org/wine/wine/-/merge_requests/7815, for https://gitlab.winehq.org/wine/wine/-/merge_requests/7226, this only split the sync ops to a separate vtable and let objects delegate theirs to a separate object.

This starts using a event-like interface for most objects, leaving the decision regarding if/how to split sync themselves / integrate inproc syncs for later.
