503e241db1 rust: Improve code formatting
Do some formatting that are in experimental stage but improve the code
readability.

Use rustfmt with a nightly toolchain and enable:

format_code_in_doc_comments = true
reorder_impl_items = true
comment_width = 100
wrap_comments = true
normalize_comments = true

(see .rustfmt.toml)

4d57ff046d rust: Prepare Cargo.toml for crates.io
Renames pv crate to s390_pv and pv_core to s390_pv_core. pv was already
taken on crates.io.

Bump the versions of all crates to 0.10.0. From now on we follow Semver
compatibility rules when it comes to updates. patch-level updates will
not introduce any backwards incompatible changes. For now all crates in
this directory will have the same version number. A version update may,
therefore, not add any new things.

Library users in this repository still use the non prefixed names and
rename the crate in the Cargo.toml. Doc-tests have to use the new name
however.

Add some Cargo metadata to the Cargo.toml.

4a76efe6d5 rust: Use AsRef<Path> and PathBuf in libraries
Use `AsRef<Path>` instead of `&Path`, &str, .... to be more versatile
and accept more input types. In addition, use `PathBuf` and `Path` for
paths instead of `String` and `str`.

87d43c7a32 rust/pv_*: Add more deny lints to pv and pv_core
Denies compiling if one of the following lints find something in pv or
pv_core:
    missing_docs,
    missing_debug_implementations,
    trivial_numeric_casts,
    unstable_features,
    unused_import_braces,
    unused_qualifications

Those lint force developers to avoid unnecessary code and providing
debuggability & documentation for each public symbol.

Fix the compile time error introduced with those lints.

381fecfc44 rust: Refactoring and reduce API surface
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

9eab43994b rust/pv: Remove internal BinGuestSecret struct
The BinGuestSecret type provides no benefits. The public GuestSecret
struct can handle everything. Therefore, move the two functions from bin
to the non-bin variant. While at it, use a struct to define the binary
structure instead of copy numbers to some positions in a Vec. This
simplifies the addition of further secret types.

Unsigned, Signed(EcSECP521R1, Rsa(2048, 3072))

As the user-data enum was not marked as non-exaustive this might be a
breaking change for users. (Not for any crate in this repo though).

The addition of such user-data is provided by following patches.

9b51b8b882 rust/pv: Refactor pv crate
Big refactoring patch of the pv crate. The main reason behind this
refactoring is to simplify testing and maintaining the pv crate while
keeping OpenSSL/libcurl dependencies optional. Using crate features
increases the number of targets that have to be tested. This refactoring
eliminates the use of features by splitting the functionality of pv into
a use OpenSSL and no-use-OpenSSL crate.

Split off some code from the pv crate into a pv_core crate. pv requires
pv_core and reexports all symbols. pv_base contains all code from former
pv that does not use OpenSSL or libcurl functionalities. The refactored
pv crate contains functionalities to generate requests and validate host
key documents. All features from pv are dropped as they are not needed
anymore and to streamline the codebase for easier use and testing. While
at it fix some documentation issues.

Users (pvsecret & pvapconfig) have next to no code change, besides the
different import of the crate.
