959: Generic, executor-agnostic queue implementation r=ivmarkov a=ivmarkov

Hopefully relatively well documented.

Implementation relies on a fixed-size `SortedLinkedList` from `heapless`. (By default, for up to 128 timer schedules, but we can lower this number to - say - 64.)

As discussed earlier, on queue overflow, the `WakerRegistration` approach is utilized, whereas the waker that is ordered first in the queue is awoken to make room for the incoming one (which might be the waker that would be awoken after all!). Wakers are compared with `Waker::will_wake`, so the queue should actually not fill up that easily, if at all.

I've left provisions for the user to manually instantiate the queue using a dedicated macro - `generic_queue!` so that users willing to adjust the queue size, or users (like me) who have to use the queue in a complex "on-top-of-RTOS-but-the-timer-driver-calling-back-from-ISR" scenario can customize the mutex that protects the queue.

The one thing I'm not completely happy with is the need to call `{ embassy_time::queue::initialize() }` early on before any futures using embassy-time are polled, which is currently on the shoulders of the user. I'm open to any ideas where we can get rid of this and do it on the first call to `_embassy_time_schedule_wake`, without introducing very complex combinations of critical sections, atomics and whatnot.

855: PDM microphone support for nrf r=Dirbaio a=pbert519

PDM microphones have a long startup phase, therefore the driver samples continuously and only switches the target buffer if the user requests sampling.

e1faf88607 Removes some of the code duplication for UarteWithIdle
This commit removes some of the code duplication for UarteWithIdle at the expense of requiring a split. As the example illustrates though, this expense seems worth the benefit in terms of maintenance, and the avoidance of copying over methods. My main motivation for this commit was actually due to the `event_endtx` method not having been copied across.

958: Implement proper `Drop` for `BufferedUarte` r=lulf a=ZoeyR

The drop method in `BufferedUarte` was prone to hanging indefinitely and also didn't actually disable the peripheral. I mostly copied over the drop method from `Uarte` with some modifications since `BufferedUarte` could have a transmit lasting indefinitely.

810: Takes care of power for nRF USB devices r=Dirbaio a=huntc

Modifies the usb-serial example to illustrate how to setup USB for situations where the USB power can be detected and removed.

Gaps:

~~* No support for the nrf-softdevices as yet, although this should be possible via another constructor.~~
* No support for the nrf5340, although this should be possible via USBREG.

The change is tested and appears to work. Some notes:

* There's an existing field named self_powered as a UsbDevice field. It doesn't ever appear to get set. I'm wondering if this field is intended to signal that a device has the nRF VBUS power situation or not. I'm not presently using it.
* The new PowerDetected event is generated on the bus initially in situations where just new is used i.e. without power management, including on STM. We can therefore rely on this event always being generated.

Old description:

~~EnabledUsbDevice is a wrapper around the `UsbDevice` where its enablement is also subject to external events, such as `POWER` events for nRF. It is introduced generically to support other platforms should they also require external signaling for enablement.~~

The field is "sort of" deprecated, it was made optional recently:

Due the the reasons listed there I believe removing it is better than
setting it to generic fluff like "The Embassy contributors".

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).

640: Skip EasyDMA slice location check for empty slices and copy data if necessary r=Dirbaio a=TilBlechschmidt

As discussed, this PR makes the following changes:
- Ignore pointer location of zero-length slices (fixes #631)
- Change default functions so they copy the tx buffer if it does not reside in RAM
- Introduce new variants for `write`, `transfer`, and their blocking versions which fails instead of copying
- Add documentation about the motivation behind all these variants
<img width="984" alt="image" src="https://user-images.githubusercontent.com/5037967/155415788-c2cd1055-9289-4004-959d-be3b1934a439.png">


Remaining TODOs:

- [x] Change copying behaviour for other peripherals
    - [x] TWI
    - [x] UART
- [x] Add module-level documentation regarding EasyDMA and `_from_ram` method variants

`@Dirbaio` it probably makes sense for you to review it now before I "copy" over the changes to the other two peripherals.

98bdac51fe Improve nRF Saadc sampling
Starting the sampling task prior to starting the SAADC peripheral can lead to unexpected buffer behaviour with multiple channels. We now provide an init callback at the point where the SAADC has started for the first time. This callback can be used to kick off sampling via PPI.

We also need to trigger the SAADC to start sampling the next buffer when the previous one is ended so that we do not drop samples - the major benefit of double buffering.

As a bonus we provide a calibrate method as it is recommended to use before starting up the sampling.

The example has been updated to illustrate these new features.

613: Rust stable support r=Dirbaio a=Dirbaio

This PR adds (limited) stable Rust support!

The drawbacks are: 

- No `#[embassy::task]`, `#[embassy::main]`. (requires `type_alias_impl_trait`). You have to manually allocate the tasks somewhere they'll live forever. See [example](https://github.com/embassy-rs/embassy/blob/master/examples/nrf/src/bin/raw_spawn.rs)
- No async trait impls (requires GATs). Note that the full API surface of HALs is still available through inherent methods: #552 #581 
- Some stuff is not constructible in const (requires `const_fn_trait_bound`), although there's an (ugly) workaround for the generic `Mutex`.

So it's not that bad in the end, it's fully usable for shipping production-ready firmwares. We'll still recommend nightly as the default, until GATs and `type_alias_impl_trait` are stable.

591: PWM WS2812B example and flexible sequence config r=Dirbaio a=huntc

I've permitted the PWM sequences to be mutated on stopping the PWM by associating them with a new  `SingleSequencer` structure. This is so that we can perform effects on the LEDs (and other use-cases, I'm sure!). The example has been updated to illustrate the use of this by flashing a WS2812B LED.

There's also a `Sequencer` structure for more sophisticated PWM interactions, along with a `pwm_double_sequence`  example to illustrate.

These changes should make it possible to attain all of the nRF PWM functionality available.

c54303be75 Makes the uarte endtx event available
This commit allows event_endtx to be used outside of the Uarte itself. As a consequence, PPI can be used to drive tasks given the end of transmission on the Uarte. This is particularly useful for situations like RS485 where a GPIO must be set to high when transmitting then cleared when done. A non-ppi approach can cause a delay in the clearing of this GPIO as other Embassy tasks might become scheduled.
