From: Twaik Yont <9674930+twaik@users.noreply.github.com> Remove the old wineandroid ioctl transport based on unixlib calls and the ntoskrnl device/IRP dispatch path. This drops the android_dispatch_ioctl entrypoint, the driver creation code, and the unixlib call table, along with the associated device thread and callback-based startup path. With the socket-based dispatch thread now handling all ioctls, the old HANDLE-based transport is no longer needed. Also remove the remaining artifacts of the old execution model, including the global JNIEnv, thread tracking, and the wrap_java_call/unwrap_java_call helpers used to work around JVM/Wine TLS conflicts. Simplify initialization accordingly by using __wine_unix_lib_init() directly, making dllmain.c consistent with winex11.drv.
