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.

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.

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.
