There was a problem hiding this comment.
This sets deadline before trace logging, while the other one sets deadline after trace logging and directly before the function call.
Let's be consistent and set in just before the function call in both places.
Always uses prefixed wasmtime-c-api-impl, otherwise the prefixed implementation bitrots. Prefixes the headers in the repo rule to allow for globbing, which is not possible in a genrule. The crates_vendor-provided wasmtime-c-api-impl provided build allows us to upgrade wasmtime solely by changing the version number in the Cargo.toml file (and the corresponding repo in bazel/repositories.bzl for the C headers).

Updating wasmtime updated a dependency used by wasmsign to an incompatible version. They're not used as part of the same build, so separate their dependency graphs by giving wasmsign its own repo name. Signed-off-by: Matt Leon <mattleon@google.com>

Hides many of the implementation details of the wasm-c-api.
Note: adds `wat` feature to wasmtime c headers to fix the following build error, but note that `wat` support is not enabled in the wasmtime build, this just adds the headers to allow the cpp api to compile.
```
