Move ioctl handling out of the Wine APC/unixlib execution path into a dedicated Java-only thread without Wine context. On Android 10+ a number of syscalls are restricted inside the activity process via seccomp, while processes started via fork/exec are not subject to the same limitations. Decoupling ioctl handling from the Wine context is required to eventually run this code outside of the activity process. This change introduces a new transport and execution model where ioctl dispatch no longer depends on Wine thread state, preparing for moving the Android backend into a separate process. The refactor is intentionally split into multiple bisect-safe commits to keep intermediate states functional while gradually migrating the dispatch path. Since this is a fairly large chunk of work, I’d like to make sure we’re aligned before continuing. -- v2: wineandroid: drop old ioctl backend startup and switch to socket transport wineandroid: add socket-based ioctl backend (unused) wineandroid: move native window registration to surface_changed wineandroid: migrate ioctl dispatch logging to Android log wineandroid: Remove redundant backend DPI scaling. https://gitlab.winehq.org/wine/wine/-/merge_requests/10569
