winebus.sys: Add code path to bypass udevd and use inotify. In a container with a non-trivial user namespace, we cannot rely on libudev communicating with udevd as a way to monitor device nodes, for the following reasons: * If uid 0 from the host is not mapped to uid 0 in the container, libudev cannot authenticate netlink messages from the host, because their sender uid appears to be the overflowuid. Resolving this by mapping uid 0 into the container is not allowed when creating user namespaces as an unprivileged user, and even when running as a privileged user, it might be desirable for the real uid 0 to not be mapped as a way to harden the security boundary between container and host. * Depending on the container configuration, initial enumeration might not be able to read /run/udev from the host system. If it can't, sysfs attributes will still work because those are read directly from the kernel via sysfs, but udev properties coming from user-space rules (in particular ID_INPUT_JOYSTICK and friends) will appear to be missing. * The protocols between udevd and libudev (netlink messages for monitoring, and /run/udev for initial enumeration) are considered to be private to a particular version of udev, and are not a stable API; but in a container, we cannot expect that our copy of libudev is at exactly the same version as udevd on the host system. Sidestep this by adding a code path that continues to use libudev for the parts that work regardless of whether udevd is running or can be communicated with.
