guix: import: Optionally import necessary yanked crates.

Browse source 
* doc/guix.texi (Invoking guix import): Mention '--allow-yanked'.
* guix/import/crate.scm (make-crate-sexp): Add yanked? argument. For
yanked packages, use the full version suffixed by "-yanked" for
generated variable names and add a comment and package property.
(crate->guix-package): Add allow-yanked? argument and if it is set to #t,
allow importing yanked crates if no other version matching the
requirements exists.
[find-package-version]: Packages previously marked as yanked are only
included if allow-yanked? is #t and then take the lowest priority.
[find-crate-version]: If allow-yanked? is #t, also consider yanked
versions with the lowest priority.
[dependency-name+version]: Rename to ...
[dependency-name+version+yanked] ...this. Honor allow-yanked? and choose
between an existing package and an upstream package.  Exit with an error
message if no version fulfilling the requirement is found.
[version*]: Exit with an error message if the crate version is not found.
(cargo-recursive-import): Add allow-yanked? argument.
* guix/read-print.scm: Export <comment>.
* guix/scripts/import/crate.scm: Add "--allow-yanked".
* tests/crate.scm: Add test 'crate-recursive-import-only-yanked-available'.
[sort-map-dependencies]: Adjust accordingly.
[remove-yanked-info]: New variable.
Adjust test 'crate-recursive-import-honors-existing-packages'.
(test-bar-dependencies): Add yanked dev-dependencies.
(test-leaf-bob-crate): Add yanked versions.
(rust-leaf-bob-3.0.2-yanked): New variable.

If @option{--recursive-dev-dependencies} is specified, also the recursively
imported packages contain their development dependencies, which are recursively
imported as well.
@item --allow-yanked
If no non-yanked version of a crate is available, use the latest yanked
version instead instead of aborting.
