uring-sys appears to be not actively developed anymore. `uring-sys2` is a fork which still receives updates and fixes. In particular, it includes changes which make it build on musl-based systems. Unlike `uring-sys`, `uring-sys2` relies fully on bindgen. Thus, a few seemingly hand-written or altered declrations whch were included in the former are not availible (at least under the same name) in `uring-sys2`. In particular, `IoRingOp` is named `io_uring_op` in `uring-sys2`. The constant `LIBURING_UDATA_TIMEOUT` is gone seemingly without a replacement. We decided to at least produce the same value. Some fns used to accept `libc::msghdr`, but `uring-sys2` includes its own version, which unfortunately is a distinct type. We did compare the definitions and deemed the layout to be identical. Other than that, the mutability changed in a few places, but we still could preserve the existing `iou` interface.
... rather than reproducing the values using bitshifts directly. In addition, used this opportunity to add flags previously missing. The order of the definitions is ascending significance of the one bit set. It's the same order used previously and in the io_uring_setup(2) man page.

At this time,
uring-sysdid not receive any updates in three and a half years. Open PRs seemingly never got merged, including one PR supplying a fix enablinguring-sysbeing built on musl-systems. For now, we have to assume it's abandoned.Luckily, a drop-in replacement which still receives updates and fixes exists in the form of
uring-sys2, a fork ofuring-sys. This PR switches over touring-sys2. In addition, it addsSetupFlagsandSetupFeaturesconstants which were introduced with newer versions ofliburing.
