guix build: Support '--with-source=PACKAGE@VERSION=URI'.
* guix/scripts/build.scm (numeric-extension?, tarball-base-name): New procedures, formerly in 'package-with-source'. (transform-package-source)[new-sources]: Look for '=' in URI. Each element of the list of now a (PKG VERSION SOURCE) tuple. Pass VERSION to 'package-with-source'. (package-with-source): Add 'version' parameter and honor it. * tests/scripts-build.scm ("options->transformation, with-source, PKG=URI") ("options->transformation, with-source, PKG@VER=URI"): New tests. * doc/guix.texi (Package Transformation Options): Document the new forms.
