chore: prepare Tokio v1.16.2 release

# 1.16.2 (February 15, 2022) This release updates the minimum supported Rust version (MSRV) to 1.49, the `mio` dependency to v0.8, and the (optional) `parking_lot` dependency to v0.12. Additionally, it contains several bug fixes, as well as internal refactoring and performance improvements. ### Fixed - time: prevent panicking in `sleep` with large durations ([#4495]) - time: eliminate potential panics in `Instant` arithmetic on platforms where `Instant::now` is not monotonic ([#4461]) - io: fix `DuplexStream` not participating in cooperative yielding ([#4478]) - rt: fix potential double panic when dropping a `JoinHandle` ([#4430]) ### Changed - update minimum supported Rust version to 1.49 ([#4457]) - update `parking_lot` dependency to v0.12.0 ([#4459]) - update `mio` dependency to v0.8 ([#4449]) - rt: remove an unnecessary lock in the blocking pool ([#4436]) - rt: remove an unnecessary enum in the basic scheduler ([#4462]) - time: use bit manipulation instead of modulo to improve performance ([#4480]) - net: use `std::future::Ready` instead of our own `Ready` future ([#4271]) - replace deprecated `atomic::spin_loop_hint` with `hint::spin_loop` ([#4491]) - fix miri failures in intrusive linked lists ([#4397]) ### Documented - io: add an example for `tokio::process::ChildStdin` ([#4479]) ### Unstable The following changes only apply when building with `--cfg tokio_unstable`: - task: fix missing location information in `tracing` spans generated by `spawn_local` ([#4483]) - task: add `JoinSet` for managing sets of tasks ([#4335]) - metrics: fix compilation error on MIPS ([#4475]) - metrics: fix compilation error on arm32v7 ([#4453]) [#4495]: #4495 [#4461]: #4461 [#4478]: #4478 [#4430]: #4430 [#4457]: #4457 [#4459]: #4459 [#4449]: #4449 [#4462]: #4462 [#4436]: #4436 [#4480]: #4480 [#4271]: #4271 [#4491]: #4491 [#4397]: #4397 [#4479]: #4479 [#4483]: #4483 [#4335]: #4335 [#4475]: #4475 [#4453]: #4453

+# 1.16.2 (February 15, 2022)
+
+This release updates the minimum supported Rust version (MSRV) to 1.49, the
+`mio` dependency to v0.8, and the (optional) `parking_lot` dependency to v0.12.
+Additionally, it contains several bug fixes, as well as internal refactoring and
+performance improvements.
+
+### Fixed
+
+- time: prevent panicking in `sleep` with large durations ([#4495])
+- time: eliminate potential panics in `Instant` arithmetic on platforms where
+  `Instant::now` is not monotonic ([#4461])
+- io: fix `DuplexStream` not participating in cooperative yielding ([#4478])
+- rt: fix potential double panic when dropping a `JoinHandle` ([#4430])
+
+### Changed
+
+- update minimum supported Rust version to 1.49 ([#4457])
+- update `parking_lot` dependency to v0.12.0 ([#4459])
+- update `mio` dependency to v0.8 ([#4449])
+- rt: remove an unnecessary lock in the blocking pool ([#4436])
+- rt: remove an unnecessary enum in the basic scheduler ([#4462])
+- time: use bit manipulation instead of modulo to improve performance ([#4480])
+- net: use `std::future::Ready` instead of our own `Ready` future ([#4271])
+- replace deprecated `atomic::spin_loop_hint` with `hint::spin_loop` ([#4491])
+- fix miri failures in intrusive linked lists ([#4397]) 
+
+### Documented
+
+- io: add an example for `tokio::process::ChildStdin` ([#4479])
+
+### Unstable
+
+The following changes only apply when building with `--cfg tokio_unstable`:
+
+- task: fix missing location information in `tracing` spans generated by
+  `spawn_local` ([#4483])
+- task: add `JoinSet` for managing sets of tasks ([#4335])
+- metrics: fix compilation error on MIPS ([#4475])
+- metrics: fix compilation error on arm32v7 ([#4453])
