import: cran: Add support for git repositories.
* guix/import/cran.scm (vcs-file?): New procedure. (download): Support downloading from git. (fetch-description): Add a clause for the 'git repository type. (files-match-pattern?): New procedure. (tarball-files-match-pattern?): Implement in terms of FILES-MATCH-PATTERN?. (directory-needs-fortran?, directory-needs-zlib?, directory-needs-pkg-config?): New procedures. (needs-fortran?, needs-zlib?, needs-pkg-config?): Rename these procedures... (tarball-needs-fortran?, tarball-needs-zlib?, tarball-needs-pkg-config?): ...to this, and use them. (file-hash): New procedure. (description->package): Handle the 'git repository type. * guix/import/utils.scm (package->definition): Handle package expression inside of a let. * guix/scripts/import.scm (guix-import): Handle let expressions. * doc/guix.texi (Invoking guix import): Document it.
