rust: pin-init: change examples to the user-space version Replace the examples in the documentation by the ones from the user-space version and introduce the standalone examples from the user-space version such as the `CMutex<T>` type. The `CMutex<T>` example from the pinned-init repository [1] is used in several documentation examples in the user-space version instead of the kernel `Mutex<T>` type (as it's not available). In order to split off the pin-init crate, all examples need to be free of kernel-specific types.

rust: pin-init: examples: mark as `#[inline]` all `From::from()`s for `Error` There was a recent request in kernel [1] to mark as `#[inline]` the simple `From::from()` functions implemented for `Error`. Thus mark all of the existing impl From<...> for Error { fn from(err: ...) -> Self { ... } } functions as `#[inline]`. While in pin-init crate the relevant code is just examples, it nevertheless does not hurt to use good practice for them.

rust: pin-init: examples: error: use `Error` in `fn main()` When running this example with no cargo features enabled, the compiler warns on 1.89: error: struct `Error` is never constructed --> examples/error.rs:11:12 \| 11 \| pub struct Error; \| ^^^^^ \| = note: `-D dead-code` implied by `-D warnings` = help: to override `-D warnings` add `#[allow(dead_code)]` Thus use the error in the main function to avoid this warning.
