* [PATCH] Add recursive CRAN importer

attached is a patch series that gives us a recursive CRAN importer. I still
haven't documented it in the manual, because I'm not sure if the
implementation is acceptable.
Simply put, the procedure that produces a package expression now returns
multiple values. The first is the package expression, the second is a list of
dependencies (with their upstream names). This allows us to go through that
list and check if any unpackaged inputs are among them.
The recursive importer stops when a package cannot be imported (e.g. when a
bioconductor package has unpackaged CRAN dependencies), or when all packages
either already existed at runtime or have been packaged.
To make this work well I had to create a list of packages that should not be
imported (because they are part of the default R installation), and I had to
make sure that R packages always get a predictable Guix package name.
Comments are very welcome!
~~ Ricardo

I have a preference fro ‘string-map’, which I find more readable than
‘regexp-substitute/global’ in simple cases. Thoughts?
Otherwise LGTM!
Thanks,
Ludo’.

Using “string-map” is indeed nicer! I’m not a fan of
“regexp-substitute/global” (and regular expressions in general), but it
didn’t occur to me to use “string-map”. Thanks for the hint.
