736: executor: allow Send-spawning of tasks if their args are Send. r=Dirbaio a=Dirbaio

This allows send-spawning (spawning into an executor in another thread) tasks if their args are Send. Previously this would require the entire future to be Send.

--


When send-spawning a task, we construct the future in this thread, and effectively
"send" it to the executor thread by enqueuing it in its queue. Therefore, in theory,
send-spawning should require the future `F` to be `Send`.

The problem is this is more restrictive than needed. Once the future is executing,
it is never sent to another thread. It is only sent when spawning. It should be
enough for the task's arguments to be Send. (and in practice it's super easy to
accidentally make your futures !Send, for example by holding an `Rc` or a `&RefCell` across an `.await`.)

Luckily, an `async fn` future contains just the args when freshly constructed. So, if the
args are Send, it's OK to send a !Send future, as long as we do it before first polling it.

1599009a4f executor: "send-spawn is OK if the args are Send" only holds for async fn futures.
The normal `spawn()` methods can be called directly by the user, with arbitrary hand-implemented futures.
We can't enforce they're only called with `async fn` futures. Therefore, make these
require `F: Send`, and add a "private" one only for use in the macro, which can enforce it.

734: executor: Add `Spawner::for_current_executor`. r=Dirbaio a=Dirbaio

This is needed to spawn non-Send tasks in an InterruptExecutor, after the fixes in #730 .

b27feb0619 executor: fix unsoundness in InterruptExecutor::start.
The initial closure is not actually called in the interrupt, so this is

716: Implement giant (chunked) DMA transfers r=Dirbaio a=matoushybl

There is a breaking change in the Channel trait in the method `remaining_transfers()`, this method however hasn't been used anywhere in the codebase and the return type changed from u16 to u32, so all of the previous use cases should work.

717: WIP: USB CDC NCM (Ethernet over USB) r=Dirbaio a=Dirbaio

TODO:

- [x] Add support for string handling in `embassy-usb`, remove the MAC addr string hax
- [x] Harden parsing of incoming NTBs to avoid panics.
- [ ] Parse all datagrams in a NDP, not just the first. -- tricky, I've made it tell the host we support only one packet per NTB instead.
- [ ] Add support for all required control transfers. -- WONTFIX, seems no OS cares about those.
- [x] Works on Linux
- [x] Doesn't work on Android, make it work
- [x] Check if it works in Windows (Win10 has some sort of CDC NCM support afaict?) -- works on Win11, CDC-NCM not supported on Win10
- [x] Check if it works in MacOS (I don't know if it's supposed to) - WORKS

I won't add the `embassy-net` driver to `embassy-usb-ncm` for now because `embassy-net` buffer management will likely be refactored soon, so there's not much point to it.

408617266e Update Rust nightly.
Fixes a new opaque type error in the task macro.
Full error is "opaque type's hidden type cannot be another opaque type from the same scope".
This got disallwed by the lazy-TAIT PR: https://github.com/rust-lang/rust/pull/94081

Sadly there's now some weird type inference errors with pre-lazy-TAIT
nightlies, so support for those is dropped.

092c2b7dfe usb: builtin handling of interface alternate settings
The stack reads its own descriptors to figure out which endpoints
are used in which alt settings, and enables/disables them as needed.

The ControlHandler has a callback so it can get notified of alternate
setting changes, which is purely informative (it doesn't have to do anything).
