Since v0.23 release of Wasmtime, if we want to iterate a directory Y then directory Y needed to have been granted `fd_readdir` right. However, it is now also required for directory X to carry `fd_readdir` right, and so on, up-chain all the way until we reach the preopen (which possesses all rights by default). This caused problems for us since our libstd implementation is more fine-grained and allowed for parent dirs not to carry the right while allow for iterating on its children. My proposal here is to always grant `fd_readdir` right as part of `std.fs.Dir.OpenDirOptions.access_sub_paths`. This seems to be the approach taken by Rust also, plus we should be justified to take this approach since WASI is experimental and snapshot1 will be discontinued eventually and replaced with a new approach to access management that will require a complete rewrite of our libstd anyhow.

The ultimate goal of the Zig project is to serve users. As a first-order effect, this means users of the compiler, helping programmers to write better software. Even more important, however, are the end-users.
Zig is intended to be used to help end-users accomplish their goals. Zig should be used to empower end-users, never to exploit them financially, or to limit their freedom to interact with hardware or software in any way.
However, such problems are best solved with social norms, not with software licenses. Any attempt to complicate the software license of Zig would risk compromising the value Zig provides.
Therefore, Zig is available under the MIT (Expat) License, and comes with a humble request: use it to make software better serve the needs of end-users.
This project redistributes code from other projects, some of which have other licenses besides MIT. Such licenses are generally similar to the MIT license for practical purposes. See the subdirectories and files inside lib/ for more details.
