39e57e3e9a Migrate back to std:: stylistically (#554)
* Migrate back to `std::` stylistically

This commit moves away from idioms such as `alloc::` and `core::` as
imports of standard data structures and types. Instead it migrates all
crates to uniformly use `std::` for importing standard data structures
and types. This also removes the `std` and `core` features from all
crates to and removes any conditional checking for `feature = "std"`

All of this support was previously added in #407 in an effort to make
wasmtime/cranelift "`no_std` compatible". Unfortunately though this
change comes at a cost:

* The usage of `alloc` and `core` isn't idiomatic. Especially trying to
  dual between types like `HashMap` from `std` as well as from
  `hashbrown` causes imports to be surprising in some cases.
* Unfortunately there was no CI check that crates were `no_std`, so none
  of them actually were. Many crates still imported from `std` or
  depended on crates that used `std`.

It's important to note, however, that **this does not mean that wasmtime
will not run in embedded environments**. The style of the code today and
idioms aren't ready in Rust to support this degree of multiplexing and
makes it somewhat difficult to keep up with the style of `wasmtime`.
Instead it's intended that embedded runtime support will be added as
necessary. Currently only `std` is necessary to build `wasmtime`, and
platforms that natively need to execute `wasmtime` will need to use a
Rust target that supports `std`. Note though that not all of `std` needs
to be supported, but instead much of it could be configured off to
return errors, and `wasmtime` would be configured to gracefully handle
errors.

The goal of this PR is to move `wasmtime` back to idiomatic usage of
features/`std`/imports/etc and help development in the short-term.
Long-term when platform concerns arise (if any) they can be addressed by
moving back to `no_std` crates (but fixing the issues mentioned above)
or ensuring that the target in Rust has `std` available.

* Start filling out platform support doc

9182971697 Add missing import to wasmtime-rust macro (#589)
This commit does two things: 1) it fixes `wasmtime_rust::wasmtime` proc macro by
adding the missing import to the `__rt` module, and fixing the scoping inside
the macro itself; and 2) it augments the `wasmtime_rust::wasmtime` proc macro with
custom error messages in case the implementor forgets the `self` argument in the
trait methods.

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.

fb60a21930 Reduce number of crates needed for Config usage
This commit is an attempt to reduce the number of crates necessary to
link to when using `wasmtime::Config` in "default mode" or with only one
or two tweaks. The change moves to a builder-style pattern for `Config`
to only require importing crates as necessary if you configure a
particular setting. This then also propagates that change to `Context`
as well by taking a `Config` instead of requiring that all arguments are
passed alone.

8b0cfd9245 Squash improper_ctypes warnings on nightly
Lots more warnings are showing up on nightly compilers due to a recent
change. I've opened rust-lang/rust#66373 on the compiler side for this
as well.

cd8cc4d375 Enable multi-value in the Python extension (#541)
This commit enables the multi-value features in the Python extension
to be usable by-default with interface types. Additionally this removes
some code which panics on multi-value but doesn't end up getting used
today.

d9edb95218 Allow using WASI APIs in the Python extension (#533)
* Allow using WASI APIs in the Python extension

This commit adds support to the Python extension to load the WASI
implementation when a WASI module is seen allowing Python to load
WebAssembly modules that use WASI. This is pretty primitive right now
because there's no way to configure the environment/args/preopens/etc,
but it's hoped to be at least a start!

* rustfmt

* Refactor checks for the wasi module name

* Move the check into `wasmtime-wasi` itself
* Make it conservative for now and match anything that says `wasi*`
* Leave a `FIXME` for improving this later on

* Enable missing feature of winapi for `winx`

a2b4148a91 General Cargo.toml cleanup. (#529)
* General Cargo.toml cleanup.

 - Remove travis-ci attributes.
 - Remove "experimental" badges from actively-developed crates.
 - Reflow some long lines.
 - Use dependency features consistently.
 - Add readme attributes

* Update WASI to the latest trunk.

This notably adds a .gitignore file for the WASI directory.
