the original C implementation was derived directly from cloudabi-utils.
that implementation is no longer in tree.
acfoltzer's initial Rust implementation included a path_open function
that was ported from cloudabi-utils. this rewrite of wasi-common has
completely delegated all path lookup functionality to cap-std (in the
cap-std-sync impls), and cap-std itself has a completely re-designed
method of path resolution.
* Publishing fixes.
* Make WASI a symlink.
* More fixes.
* Cargo doesn't allow dev-dependencies to have optional features.
* Remove the symlink.
* Add WASI as another git submodule.
* Fix feature-gating of test-programs
This commit fixes bugs in enabling feature-gating of `test-programs`
which was introduced in #600. It turns out, #600 accidentally
disabled `test-programs` from ever running, and this commit fixes
that.
* Fix the CI
