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.
