Cargo dependencies names now include the API version

Cargo dependencies names are now in the format <package_name>-<version>-rs:

• package_name is defined in [package] name = ... section of the Cargo.toml.
• version is the API version deduced from [package] version = ... as follow:
  • x.y.z -> 'x'
  • 0.x.y -> '0.x'
  • 0.0.x -> '0' It allows to make different dependencies for uncompatible versions of the same crate.
• -rs suffix is added to distinguish from regular system dependencies, for example gstreamer-1.0 is a system pkg-config dependency and gstreamer-0.22-rs is a Cargo dependency.

That means the .wrap file should have dependency_names = foo-1-rs in their [provide] section when Cargo.toml has package name foo and version 1.2.

This is a breaking change (Cargo subprojects are still experimental), previous versions were using <package_name>-rs format.
