21e0a99884 Delete the wasmtime-wasi-c crate (#844)
This commit deletes the old C implementation of the original
`wasi_unstable` module, instead only leaving around our single
`wasmtime-wasi` crate as the implementation for both
`wasi_snapshot_preview1` and `wasi_unstable`.

This hasn't been discussed (AFAIK) up until now, so this is also a
proposal! Some thoughts in favor of this deletion I would have are:

* This has been off-by-default for ages
* We don't build or test any of this on CI
* Published binaries with `wasmtime` do not have this possibility
  enabled
* Future refactorings to the `wasmtime-wasi` crate will either need to
  work around how the C implementation is different or bring it up to
  speed.

This is motivated by the last bullet point where I was working on
getting `wasmtime-wasi` working purely as an implementation detail on
top of the `wasmtime` crate itself, but quickly ran into a case where
the CLI would need to multiplex all sorts of wasi implementations. In
any case I'm curious what others think, is this too soon? Is there
something remaining blocking this? (etc)

9a88d3d894 Replace the global-exports mechanism with a caller-vmctx mechanism. (#789)
* Replace the global-exports mechanism with a caller-vmctx mechanism.

This eliminates the global exports mechanism, and instead adds a
caller-vmctx argument to wasm functions so that WASI can obtain the
memory and other things from the caller rather than looking them up in a
global registry.

This replaces #390.

* Fixup some merge conflicts

* Rustfmt

* Ensure VMContext is aligned to 16 bytes

With the removal of `global_exports` it "just so happens" that this
isn't happening naturally any more.

* Fixup some bugs with double vmctx in wasmtime crate

* Trampoline stub needed adjusting
* Use pointer type instead of always using I64 for caller vmctx
* Don't store `ir::Signature` in `Func` since we don't know the pointer
  size at creation time.
* Skip the first 2 arguments in IR signatures since that's the two vmctx
  parameters.

* Update cranelift to 0.56.0

* Handle more merge conflicts

* Rustfmt

ef2177ed3a Update to the latest spec_testsuite and dependencies. (#803)
* Update to the latest spec_testsuite and dependencies.

Update to target-lexicon 0.10, cranelift 0.54, wast 0.6, faerie 0.14,
and the latest spec_testsuite.

For wast and cranelift-wasm, update the code for API changes.

* Factor out the code for matching f32, f64, and v128.

This takes the idea from #802 to split out `f32_matches`, `f64_matches`,
and `v128_matches` functions, which better factor out the matching
functionality between scalar and vector.

068c249439 Add code to publish-all.sh for bumping path dependency versions. (#792)
In a multi-crate repo, path dependencies still need to specify versions
when publishing on crates.io. This adds a very simple way to keep all
these versions in sync.

c5f998add2 Update the crates.io publishing scripts (#580)
* Fix fuzz target compilation.

* Bump version to 0.7.0

* Temporarily disable fuzz tests

Temporarily disable fuzz tests until https://github.com/bytecodealliance/cranelift/issues/1216 is resolved.

* Fix publish-all.sh to not modify the witx crate.

* Remove the "publish = false" attribute from Lightbeam.

* Add a README.md for wasmtime-interface-types.

* Remove the "rust" category.

This fixes the following warning:

warning: the following are not valid category slugs and were ignored: rust. Please see https://crates.io/category_slugs for the list of all category slugs.

* Mark wasmtime-cli as "publish = false".

* Sort the publishing rules in topological order.

Also, publish nightly-only crates with cargo +nightly.
