Auto merge of #2349 - saethlin:isatty, r=RalfJung
Improve isatty support Per https://github.com/rust-lang/miri/issues/2292#issuecomment-1171858283, this is an attempt at > do something more clever with Miri's `isatty` shim Since Unix -> Unix is very simple, I'm starting with a patch that just does that. Happy to augment/rewrite this based on feedback. The linked file in libtest specifically only supports stdout. If we're doing this to support terminal applications, I think it would be strange to support one but not all 3 of the standard streams. The `atty` crate contains a bunch of extra logic that libtest does not contain, in order to support MSYS terminals: https://github.com/softprops/atty/commit/db8d55f88eabfcc22cde39533c2b1d688d1cdfc6 so I think if we're going to do Windows support, we should probably access all that logic somehow. I think it's pretty clear that the implementation is not going to change, so I think if we want to, pasting the contents of the `atty` crate into Miri is on the table, instead of taking a dependency.
