implement Component Model async ABI (#11127)* implement Component Model async ABIThis commit replaces the stub functions and types in`wasmtime::runtime::component::concurrent` and its submodules with the workingimplementation developed in the `wasip3-prototyping` repo. For ease of review,it does not include any new tests; I'll add those in a follow-up commit.Note that this builds on #11123; only the most recent commit is new.Signed-off-by: Joel Dice * clear params pointer in `call_async` when future is droppedThis ensures that the closure we pass to `prepare_call` will never see a stalepointer.Note that this could potentially be made more efficient; I'm starting with asimple solution, and we can refine from there.Signed-off-by: Joel Dice * Remove unsafety from accessing concurrent async state* Remove a dead variant when async is disabled* Add tests for `tls.rs` unsafe code* Refactor `AbortHandle`* Don't close over the entire future in the `AbortHandle`, instead change it to just the bare minimum state to manage aborts.* Move aborting logic into a helper `AbortHandle::run` function which handles the is-this-aborted-check internally.* Refactor some logic around spawns how `AbortHandle` is managed/created.* Internalize some functions/types* add FIXME comment to `states.rs`Signed-off-by: Joel Dice * reference issue 11190 in `table.rs` TODOSigned-off-by: Joel Dice * switch `use` directives to conventional syntaxSigned-off-by: Joel Dice * remove redundant accessor methodsSigned-off-by: Joel Dice * reference issue 11191 in `yield` TODO commentsSigned-off-by: Joel Dice * replace `dummy_waker` with `Waker::noop`Signed-off-by: Joel Dice * remove obsolete `AsyncState::spawned_tasks` fieldSigned-off-by: Joel Dice * only call post-return automatically for `call_concurrent`This restores the original behavior of requiring explicit post-return calls for`call[_async]` invocations.Signed-off-by: Joel Dice * Favor function arguments before closures* Simplify `watch` a bitMostly move unnecessary state out of the `Arc`.* fix task handle leaks and add test coverageWe weren't always disposing of guest or host task handles once they becameunreachable. This adds a couple of hidden methods which integration tests mayuse to guard against use-after-delete, double-delete, and leak bugs regardingwaitable handles. It also tightens up handle management in `concurrent.rs` toensure those tests pass.Signed-off-by: Joel Dice * Encapsulate type erasure in stream buffersDon't rely on all buffers to handle `TypeId` and assertions and such,instead have a helper type which is the one location of the assertionsand everything else can stay typed.* Remove some methods ending in underscores* Refactor unsafety in `buffers.rs`Mostly move away from raw pointers and instead use utilities like`&[MaybeUninit]`. Also make `WriteBuffer` an `unsafe` trait afterabsorbing the `TakeBuffer` trait. Update all safety-related commentshere and there too.* remove task on drop in `TypedFunc::call_async`This avoids the need for an `Arc`.Signed-off-by: Joel Dice * remove obsolete clause from `FutureReader::read` docsSigned-off-by: Joel Dice * unhide and expand docs for `WriteBuffer` and `ReadBuffer`Signed-off-by: Joel Dice * add optional `component-model-async-bytes` featureThis gates interop with the `bytes` crate, making it optional and non-default.Signed-off-by: Joel Dice ---------Signed-off-by: Joel Dice Co-authored-by: Alex Crichton List of files: /wasmtime-44.0.1/crates/wasmtime/src/runtime/component/concurrent/tls.rs
