Fix memory leak of @template_raw. The documentation of CString::into_raw
reads:
"Consumes the CString and transfers ownership of the string to a C
caller.
...
Failure to call CString::from_raw will lead to a memory leak." [1]
Let's fix the memory leak by always calling `CString::from_raw` and
therefore reclaim the ownership.

Rename the previous "default" `new` constructor [1] to `with_prefix` and
add a new default `new` constructor that takes no argument is therefore
easier to use.
In addition, improve the overall documentation, add more tests, and
examples to the code.

Prepare pv & pv_core crates to be released on crates.io:
* Remove any unused API to stay flexible
* Remove utils dependency
* Move cli, tmpfile and version utilities to local utils crate
* Use the new utilities in the pv tools
* Rename Secret into Confidential to avoid confusion of Secret (now
Confidential) and AddSecret requests.
* Move the uvsecret module out of the request module and change the name
to secret.
* Cleanup dependencies
* Precise and correct minimal dependency versions
* Inline `Aes256Key::from_digest`
The cleanup ensures that the code also compiles with the dependencies
resolved to their minimal versions using:
$ cargo +nightly -Z minimal-versions update
$ cargo build
