[bug#67960] [PATCH 0/4] Improve the crate importer.

[David Elsing <david.elsing@posteo.net>]

This patch series contains improvements to the crate importer.

The first patch fixes the memoization in crate-recursive-import.

The second patch allows for including the cargo-development-inputs also in
recursively imported crates by specifying --recursive-dev-dependencies, such
that the tests of all imported crates can be run.

The third patch removes the dependency of a test in tests/crate.scm on an
existing crate in gnu/packages/crates.io.

Sometimes, it can happen that a crate requires a dependency for which only a
yanked version exists, which is addressed in the fourth patch. Instead of
simply failing, I changed the behavior to also import yanked versions if no
non-yanked version exists. Then, they can be used anyway or be manually
patched out from the dependent packages. Their packages obtain a different
package name (including the full version) and a package property marking them
as yanked. The logic to decide which version to use naturally became more
complicated as a result.

David Elsing (4):
  gnu: import: Fix memoization in crate-recursive-import.
  import: crate: Optionally import dev-dependencies recursively.
  tests: Mock find-packages-by-name in crate importer test.
  guix: import: Optionally import necessary yanked crates.
