* use dyn Trait syntax where appropriate recent rust nightly started warning that not using `dyn` was deprecated. This requires MSRV 1.27.0+. * rustfmt fallout from dyn additions * stop explicit allow of rust_2018_idioms * more dyn Trait syntax * drop tokio-macros from 0.1.x workspace Since tokio-macros specifies an edition=2018, we would otherwise require MSRV 1.31.0 to build/test it. And tokio-macros isn't used with tokio 0.1.x. * reactor: narrow tokio-io-pool dev dep to 0.1.4 Since 0.1.5-6 is now a edition=2018 crate, which has effective MSRV 1.31.0. * narrow tempfile dev-dep to avoid MSRV bump tempfile 3.1.0 pulls in rand 0.7.0 and is MSRV 1.32.0 * narrow flate2 dev-dep to avoid MSRV bump flate2 1.0.10-11 have MSRV 1.34.0. github refs: alexcrichton/flate2-rs#207 * fs: drop deprecated tempdir crate use in tests In particular because it pulls in old rand duplicates. Replace use with tempfile::tempdir() which has been available since tempfile 3.0.0. backport-of: #1312 * increase CI MSRV to 1.28.0
