7890fa6705 Use __chkstk for aarch64 instead of __rust_probestack. (#800)
* Use __chkstk for aarch64 instead of __rust_probestack.

* Demote rustdoc to a regular comment to fix the build.

d81aa203bb Disable rustdoc on the wasmtime cli binary (#834)
Currently the wasmtime binary (src/bin/wasmtime) and the wasmtime API
crate (crates/api) share the same output filename.  This causes the
output files of the wasmtime binary to clobber the output files of the
wasmtime API crate.   So running `cargo doc --all` will often not build
the wasmtime API docs, which is the more useful of the two.

This is a rustdoc bug, and can be worked around by disabling
documentation for the wasmtime binary.

e5afdd2ede Document the wasmtime::Instance APIs (#814)
* Document the `wasmtime::Instance` APIs

This documents oddities like the import list and export list and how to
match them all up. Addtionally this largely just expands all the docs
related to `Instance` to get filled out.

This also moves the `set_signal_handler` functions into
platform-specific modules in order to follow Rust idioms about how to
expose platform-specific information. Additionally the methods are
marked `unsafe` because I figure anything having to do with signal
handling is `unsafe` inherently. I don't actually know what these
functions do, so they're currently still undocumented.

* Fix build of python bindings

* Fix some rebase conflicts

5f1c0eb86b Generate strerror from witx; tweak Display for WasiError (#832)
This commit introduces two small changes:
* it adds `gen_errno_strerror` to `wig` crate which generates a
  `strerror` function for `__wasi_errno_t` directly from `*.witx`,
  similarly to how it's done in the `wasi` crate
* it tweaks `WasiError` type to include the error message generated
  with `strerror` when displaying the error

e474a9e822 [wasi-common] Log string representation of WASI errno at the trace level (#760)
* Log str repr of WASI errno at trace level

This commit refactors `Error` enum, and adds logging of the WASI
errno string representation at the trace level. Now, when tracing
WASI syscalls, we will be greeted with a nicely formatted errno
value after each syscall:

```
path_open(...)
     | *fd=5
     | errno=ESUCCESS
```

This commit gets rid of `errno_from_nix`, `errno_from_win` and
`errno_from_host` helper fns in favour of direct `From` implementations
for the relevant types such as `yanix::Errno` and `winx::winerror::WinError`.
`errno_from_host` is replaced by a trait `FromRawOsError`.

* Back port changes to snapshot0

* Fix indentation in logs

0be3c2983c Remove the Context type from wasmtime (#825)
* Remove the `Context` type from `wasmtime`

This hasn't really ended up being used in all that many places and the
dependencies on it were pretty minimal. This commit removes it in favor
of simplifying its various users a bit and/or leveraging the
`Engine`/`Store` structures where possible.

e7e08f162d Preserve full native stack traces in errors (#823)
* Preserve full native stack traces in errors

This commit builds on #759 by performing a few refactorings:

* The `backtrace` crate is updated to 0.3.42 which incorporates the
  Windows-specific stack-walking code, so that's no longer needed.
* A full `backtrace::Backtrace` type is held in a trap at all times.
* The trap structures in the `wasmtime-*` internal crates were
  refactored a bit to preserve more information and deal with raw
  values rather than converting between various types and strings.
* The `wasmtime::Trap` type has been updated with these various changes.

Eventually I think we'll want to likely render full stack traces (and/or
partial wasm ones) into error messages, but for now that's left as-is
and we can always improve it later. I suspect the most relevant thing we
need to do is to implement function name symbolication for wasm
functions first, and then afterwards we can incorporate native function
names!

* Fix some test suite assertions

1d504ecf6d Correctly count the number of wasm parameters. (#1337)
* Correctly count the number of wasm parameters.

Following up on #1329, this further replaces `num_normal_params` with a function
which calls `is_wasm_parameter` to correctly count the number of wasm
parameters a function has.

* Move is_wasm_parameter's implementation into the trait.

364fa994ed Move the C API to a separate crate (#818)
* Move the C API to a separate crate

This commit moves the C API from `crates/api/src/wasm.rs` to
`crates/capi/src/lib.rs` to be located in a separate crate. There's a
number of reasons for this:

* When a Rust program depends on the `wasmtime` crate, there's no need
  to compile in the C API.
* This should improve compile times of the `wasmtime` crate since it's
  not producing artifacts which aren't always used.
* The development of the C API can be guaranteed to only use the public
  API of the `wasmtime` crate itself.

Some CI pieces are tweaked and this overall shouldn't have much impact
on users, it's intended that it's a cleanup/speedup for developers!

* Disable rustdoc/tests for capi

* Review feedback

* Add back in accidentally deleted comment

* More renamings

* Try to fix dotnet build

3a13f79b66 Try to reduce CI times with a Rust *.wat parser (#1332)
This commit moves the cranelift tests and tools from the `wabt` crate on
crates.io (which compiles the wabt C++ codebase) to the `wat` crate on
crates.io which is a Rust parser for the `*.wat` format. This was
motivated by me noticing that release builds on Windows are ~5 minutes
longer than Linux builds, and local timing graphs showed that `wabt-sys`
was by far the longest build step in the build process.

This commit changes the `clif-util` binary where the `--enable-simd`
flag is no longer respected with the text format as input, since the
`wat` crate has no feature gating. This was already sort of not
respected, though, since `--enable-simd` wasn't consulted for binary
inputs which `clif-util` supports as well. If this isn't ok though then
it should be ok to close this PR!
