949: (embassy-rp): Implement RealTimeClock r=lulf a=MathiasKoch
Basically a 1:1 port of the great implementation effort made by `rp-hal`
Co-authored-by: Mathias <mk@blackbird.online>
957: Take into account size of revert index r=lulf a=lulf
Fixes a bug in the partition assertions that ensures that the state page(s) have enough space for 2x active partition range.
Add unit test to verify that panic is observed.

956: Remove BootFlash borrow r=lulf a=lulf
Compiler will infer a different lifetime for BootFlash than for the borrowed flash, which makes it require more type annotations than if it was just owning the type. Since it doesn't really matter if it owns or borrows in practical use, change it to own so that it simplifies usage.

950: Add .into_inner() and .get_mut() to Mutex r=Dirbaio a=hulthe
Similar to the methods on std Mutex, these methods allow accessing the underlying data without locking the mutex when you have exclusive access to it.

948: (embassy-stm32): make `State::new()` const, consistent with others r=Dirbaio a=FrozenDroid

946: sync/signal: wake old waker on overflow instead of panicking. r=Dirbaio a=Dirbaio
This makes behavior consistent with `WakerRegistration`. It allows canceling `wait` in one task and then calling `wait` in another. If two tasks are `wait`ing concurrently the signal will be received by only one of them, randomly.

This commit add two constants and updates the comment about ALP.
It was not easy to find the definition of ALP but after searching I
found what I believe is the correct definition in section 3.3 "Clocks"
in the referenced document below.
Active Low Power (ALP):
Supplied by an internal or external oscillator. This clock is
requested by cores when accessing backplane registers in other cores
or when performing minor computations. When an external crystal is
used to provide reference clock, ALP clock frequency is determined by
the frequency of the external oscillator. A 37.4 MHz reference clock
is recommended.

This commit uses wrapping_sub for subtraction in update_credit.
The motivation for this is that currently the rpi-pico-w example panics
(at least for me) with the following error:

error: could not compile `embassy-exploration` due to previous error
```
I ran into this when updating an [example project](https://github.com/danbev/learning-rust/tree/master/embassy) I have to use `embassy-executor`.
----
### Reproduce
Create a new project:
```console
$ cargo new --bin embassy-standalone
$ cd embassy-standalone
```
Update `Cargo.toml`:
```toml
[package]
name = "embassy-standalone"
version = "0.1.0"
edition = "2021"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
[dependencies]
embassy-executor = { version = "0.1.0", features = ["std", "integrated-timers", "nightly"] }
embassy-time = { version = "0.1.0", features = ["defmt", "defmt-timestamp-uptime", "std", "nightly"] }
log = "0.4.14"
env_logger = "0.9.0"
#critical-section = { version = "1.1", features = [ "std" ] }
[patch.crates-io]
embassy-executor = { git = "https://github.com/embassy-rs/embassy", branch = "master" }
embassy-time = { git = "https://github.com/embassy-rs/embassy", branch = "master" }
```
Notice the commented out `critical-section` dependency which will produces the link error.
Update `src/main.rs` with the code from [embassy.dev/dev/examples.html](https://embassy.dev/dev/examples.html):
```rust
#![feature(type_alias_impl_trait)]
use embassy_executor::Spawner;
use embassy_time::{Duration, Timer};
use log::*;
#[embassy_executor::task]
async fn run() {
loop {
info!("tick");
Timer::after(Duration::from_secs(1)).await;
}
}
#[embassy_executor::main]
async fn main(spawner: Spawner) {
env_logger::builder()
.filter_level(log::LevelFilter::Debug)
.format_timestamp_nanos()
.init();
spawner.spawn(run()).unwrap();
}
```
Running the example:
```console
$ cargo r
```
