This works on Linux, Android, Windows, macOS, FreeBSD, NetBSD, OpenBSD, DragonFlyBSD, Solaris and Illumos. Newly supported compared to the C version is Windows. Compared to the C version various error paths are handled more correctly and a couple of memory leaks are fixed. Otherwise it should work identically. The minimum required Rust version for compiling this is 1.48, i.e. the version currently in Debian stable. On Windows, Rust 1.54 is needed at least. Fixes https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/1259 Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3889>
