[pbs-devel] [PATCH-SERIES 0/20] update to tokio 1.0 and friends

[Fabian Grünbichler]

this series updates to tokio 1.0 and related crates:
- bytes 1
- openssl 0.10
- tokio-openssl 0.6.1
- hyper 0.14
- h2 0.3
- tokio-stream (new, split out)
- tokio-util 0.6
- rustyline 7
- pin-project 1
- nix 0.19.1
- crossbeam-channel 0.5

the main changes are:
- mio no longer exposed by tokio, PollEvented is replaced by AsyncFd
- tokio runtime setup / interface was adapted
- tokio Stream code got split into a separate crate until std::stream exists
- tokio::io::AsyncRead using ReadBuf
- tokio::time::{Sleep,Timeout} no longer Unpin and renamed (delay -> sleep)
- tokio-openssl API changed
- hyper HTTP2 upgrade API changed

the recently introduced TimeoutFutureExt from the proxmox crate is dropped in
favour of using tokio::time::timeout directly, since it only had three call
sites.

the unused futures-io feature (and related code) in pxar was dropped.

all the important Stream wrappers/adapters now exist in tokio-stream.

AFAICT no performance regression or otherwise (anymore)
