8335484870 Update wasm32.rs to name the union fields. 
The upstream wasi/core.h header switched from anonymous unions to unions
named `u`. This patch updates wasm32.rs to reflect this, as was done in
wasmtime 5b77f952.

5c14d1eb6f Add link to Rust version of the WASI tutorial 
I thought it might be useful for future WASI users to have the WASI tutorial written not only in C but also in Rust.

I'm also happy to keep the tutorial up to date with the current state of WASI target in Rust.

In more detail, this commit:
* makes fd_prestat_get safe

b0eab7398d Don't decode the incoming events to poll_oneoff. (#113) 
The events array is an output-only array, so we don't need to decode its
contents.

049c926e08 Handle set-size rights correctly when truncating a file. 
If a path_open call is requesting __WASI_RIGHT_FD_FILESTAT_SET_SIZE,
interpret that as a request for write privleges. If it is requesting
O_TRUNC, require __WASI_RIGHT_PATH_FILESTAT_SET_SIZE, since this is
a path operation rather than a FD operation.

29c2616484 Update the documentation about C/C++ toolchain limitations. 
Document that `setjmp`/`longjmp` and C++ exceptions are unsupported, and
update the documentation about the function signature mismatch bug to
reflect that it's now just a warning rather than a fatal error.

f10cd2f4b1 Don't allow a preopened file descriptor to be renamed over. 
This is consistent with fd_close's behavior, and is likely temporary
until other options are designed.

4262178cf5 Document the git clone --recurse-submodules requirement. 
Currently, it's necessary to do this in order to obtain a lightbeam
checkout, in order to build wasmtime.

I'm very interested in learning about better ways to solve this problem.
