derivations: 'derivation' and related procedures return a single value. * guix/derivations.scm (derivation->output-path, derivation->output-paths): New procedures. (derivation-path->output-path): Use 'derivation->output-path'. (derivation-path->output-paths): Use 'derivation->output-paths'. (derivation): Accept 'derivation?' objects as inputs. Return a single value. (build-derivations): New procedure. (compiled-modules): Use 'derivation->output-paths'. (build-expression->derivation)[source-path]: Add case for when the input matches 'derivation?'. [prologue]: Accept 'derivation?' objects in INPUTS. [mod-dir, go-dir]: Use 'derivation->output-path'. * guix/download.scm (url-fetch): Adjust to the single-value return. * guix/packages.scm (package-output): Use 'derivation->output-path'. * guix/scripts/build.scm (guix-build): When the argument is 'derivation-path?', pass it through 'read-derivation'. Use 'derivation-file-name' to print out the .drv file names, and to register them. Use 'derivation->output-path' instead of 'derivation-path->output-path'. * guix/scripts/package.scm (roll-back): Adjust to the single-value return. (guix-package): Use 'derivation->output-path'. * guix/ui.scm (show-what-to-build): Adjust to deal with 'derivation?' objects instead of .drv file names. * gnu/system/grub.scm (grub-configuration-file): Use 'derivation->output-path' instead of 'derivation-path->output-path'. * gnu/system/vm.scm (qemu-image, system-qemu-image): Likewise. * tests/builders.scm, tests/derivations.scm, tests/packages.scm, tests/store.scm, tests/union.scm: Adjust to the new calling convention. * doc/guix.texi (Defining Packages, The Store, Derivations): Adjust accordingly.
