We have reports of runtime panics (linkerd/linkerd2#7748) that sound a lot like rust-lang/rust#86470. We don't have any evidence that these panics originate in h2, but there is one use of `Instant::sub` that could panic in this way. Even though this is almost definitely a bug in Rust, it seems most prudent to actively avoid the uses of `Instant` that are prone to this bug. These fixes should ultimately be made in the standard library, but this change lets us avoid this problem while we wait for those fixes. This change replaces uses of `Instant::elapsed` and `Instant::sub` with calls to `Instant::saturating_duration_since` to prevent this class of panic. See also hyperium/hyper#2746
…h decoded Decoding error when processing continuation header which contains normal header name at boundary
## Motivation
Currently, the `tracing` spans for the client and server handshakes
contain the name of the I/O type. In some cases, where nested I/O types
are in use, these names can be quite long; for example, in Linkerd, we
see log lines like this:
```

```
which is kinda not great.
## Solution
This branch removes the IO type's type name from the spans for the
server and client handshakes. In practice, these are not particularly
useful, because a given server or client instance is parameterized over
the IO types and will only serve connections of that type.
# 0.3.12 (March 9, 2022) * Avoid time operations that can panic (hyperium#599) * Bump MSRV to Rust 1.49 (hyperium#606) * Fix header decoding error when a header name is contained at a continuation header boundary (hyperium#589) * Remove I/O type names from handshake `tracing` spans (hyperium#608)

Looks like there is finally some movement on letting us unfork (hyperium#612), but it's not in yet.
This should not be squash-merged, since that will make future upgrades painful.
