…si-cli wasi-cli import is sum of WebAssembly/wasi-cli#19 and WebAssembly/wasi-cli#20
it turns out this isnt semantically meaningful, since the package name is in the document itself now, but lets be consistient
…rminal CI environments vary - let the test runner make sure the host process's stdio is in fact a terminal before asserting that the guest sees it is a terminal.
which means making a newtype around Stdout and Stderr instead of using a type alias there. and then use the is-terminal impl to fill in the isatty field in the builder when inheriting. if you need to override it you can always builder.stdin(stdio::stdin(), your_own_idea_of_isatty)

…e#6806) * rename wasi-cli-base to wasi-cli, delete `preview` package, import wasi-cli wasi-cli import is sum of WebAssembly/wasi-cli#19 and WebAssembly/wasi-cli#20 * wasi impl: change bindgen arguments and mod paths from cli_base to cli * correct name of wasi-cli deps dir to just `deps/cli/` it turns out this isnt semantically meaningful, since the package name is in the document itself now, but lets be consistient * track whether stdio isatty in ctx, and impl the cli/terminal-* interfaces * rebase fixup * wasi wits: define the reactor adapter's world * component adapter: fixes * test-programs/command-tests: fix renaming cli_base to cli * component adapter: fix manually-defined export and import names * test harness fixes * preview1 component adapter: fill in isatty detection * implement isatty in preview2-to-preview1 host adapter * test-programs: cover both when stdio isatty and not prtest:full * split isatty test for regular file and stdio, detect host stdio is_terminal CI environments vary - let the test runner make sure the host process's stdio is in fact a terminal before asserting that the guest sees it is a terminal. * provide an is-terminal impl for all preview2's stdio types which means making a newtype around Stdout and Stderr instead of using a type alias there. and then use the is-terminal impl to fill in the isatty field in the builder when inheriting. if you need to override it you can always builder.stdin(stdio::stdin(), your_own_idea_of_isatty) * finally, rename IsATTY variants to Yes and No * Fix the reference to IsATTY::No * more forgotten renamings --------- Co-authored-by: Trevor Elliott <[email protected]>

This PR synchronizes the wasi:cli package with the upstream spec definition.
As part of this PR I upstreamed changes from the wasmtime repo:
WebAssembly/wasi-cli#19
WebAssembly/wasi-cli#20
The changes arriving downstream in this change are
terminal-{input, output, stdin, stdout, stderr}functions to the cli implementation, which allows us to implementisatty, bringing preview2's view of stdio to parity with preview 1, where fd_filestat_get could be used to determine whether stdio were ttys. I made some changes in wasi-tests to exercise this functionality to show that it works in all 5 of our WASI implementations. (yes i roll my eyes every time i type all 5 wasi implementations too. because i wrote them. what have i done. what did they do to us)
