589: Fine grained concurrency on thumbv6m (no BASEPRI). r=korken89 a=perlindgren
This is an experimental implementation of SRP based scheduling on the M0/M0+ (thumbv6m) architecture.
The aim is a (sub)-zero abstraction to the resource protection (locking mechanism).
Please try, but not merge yet, since its an early POC.

Looking at the Clippy [wildcard-imports rule](https://rust-lang.github.io/rust-clippy/master/#wildcard_imports)
the exception is for wildcards on modules named prelude. Thus, `prelude::*` is OK.
Current state: `use rtic-core::prelude as mutex_prelude` almost fits the bill, but `mutex_prelude != prelude`.
As this was part of user facing API I don’t think we can remove the current setup,
so rtic-core `Mutex`, `Exclusive` and multi-lock `TupleExt0X` retained in
old location to be backwards compatible.

610: GHA: Print current crate version too r=perlindgren a=AfoHT
613: Docs: fix link r=perlindgren a=AfoHT
Co-authored-by: Henrik Tjäder <henrik@grepit.se>
606: GHA: Automatic merge to release/vX r=perlindgren a=AfoHT
- Require clippy for deploy
- GHA: Automatic merge to release/vX
- Link dev-book to stable if they are describe the same release
- Update CHANGELOG
Development work is done in the master branch
Older versions previously were found in v0.5.x, v0.4.x branches.
Now with v1 released, and any breaking change forcing a v2,
a need to streamline documentation building arose.
The different docs:
- rtic.rs
- latest stable (v1)
- API documentation
- RTIC book
- old stable (v0.5)
- API documentation
- RTIC book
- oldold stable (v0.4)
- API documentation
- RTIC book
- docs.rs
- all previous crates.io releases
- API documentation
With this PR, when a pull request gets merged to master
with CI passing the current master branch gets merged
to `release/v$VERSION` where `$VERSION` is parsed from
cargo metadata of cortex-m-rtic.
The deployment of docs GHA job is dependent on this merge job,
and therefore the docs published to rtic.rs will contain the latest
content from the merged PR.
Assuming the current situation where `v1` is the latest stable,
a PR should trigger a merge to `release/v1` and then docs gets pushed
to `gh-pages` branch (rtic.rs).
For the future, when the latest stable is still `v1`, but the current
dev version in `master` branch is `v2` the GHA job will push to `release/v2` (dev branch).
For the future we might decide if this push of the dev branch is desirable.
If the current stable version and dev version share the same major version,
the dev book redirection on rtic.rs will point to the stable book instead.

593: RTIC macro expansion: Try to find target-dir r=korken89 a=AfoHT
Seems over-engineered, but for projects where
```
[build]
target-dir = "target"
```
is set to anything other than default `target` RTIC did simply not produce any `rtic-expansion.rs`.
This changes the approach to not giving up if not finding `target/` by looking at `OUT_DIR` and traversing back until `TARGET` is found.
As the `TARGET` target-triple variable is not available, approximate the `TARGET` folder (found in `target-dir`) with `s.starts_with("thumbv")`.
`target-dir` as set in `.cargo/config` will now be the parent directory of the `Path` ending with `TARGET`
## Example running with default target:
```
cortex-m-rtic on expansionoutdir [$!?] is 📦 v1.0.0 via R v1.58.0 took 4s
❯ cargo build --example spawn --target thumbv7em-none-eabihf
OUT_DIR
"/home/henrik/rust/rtic/cortex-m-rtic/target/thumbv7em-none-eabihf/debug/build/cortex-m-rtic-5bd81e8412a790d5/out"
target/ exists
Write file:
target/rtic-expansion.rs
Finished dev [unoptimized + debuginfo] target(s) in 7.20s
```
## Contrived example
With `.cargo/config` containing:
```
[build]
target-dir = "/tmp/cargothingy/../rust/./target/cargo"`
```
```
cortex-m-rtic on expansionoutdir [$!?] is 📦 v1.0.0 via R v1.58.0 took 3s
❯ cargo build --example spawn --target thumbv7em-none-eabihf
OUT_DIR
"/tmp/cargothingy/../rust/./target/cargo/thumbv7em-none-eabihf/debug/build/cortex-m-rtic-5bd81e8412a790d5/out"
"/tmp/cargothingy/../rust/./target/cargo"
Write file:
/tmp/cargothingy/../rust/./target/cargo/rtic-expansion.rs
Finished dev [unoptimized + debuginfo] target(s) in 6.42s
```
## Less extreme with relative paths
```
[build]
target-dir = "../../cargothingy/target/buildfiles/and-stuff"
```
```
OUT_DIR
"/home/henrik/rust/rtic/cortex-m-rtic/../../cargothingy/target/buildfiles/and-stuff/thumbv7em-none-eabihf/debug/build/cortex-m-rtic-5bd81e8412a790d5/out"
"/home/henrik/rust/rtic/cortex-m-rtic/../../cargothingy/target/buildfiles/and-stuff"
Write file:
/home/henrik/rust/rtic/cortex-m-rtic/../../cargothingy/target/buildfiles/and-stuff/rtic-expansion.rs
Finished dev [unoptimized + debuginfo] target(s) in 6.78s
```
Note: If the user creates a folder named target in the same directory where `Cargo.toml`/crate root is, that will be used for storing the expansion.
```

595: Update tips_monotonic_impl.md r=AfoHT a=jordens
* There is no RTIC 0.6, only several RCs.
* Timers without interrupts (like the DWT cycle counter alone) will not be useful for `Monotonic` impls.
* Clarified some of the descriptions of the various implementations.
