store-copy: 'populate-store' can optionally deduplicate files.
Until now deduplication was performed as an additional pass after copying files, which involve re-traversing all the files that had just been copied. * guix/store/deduplication.scm (copy-file/deduplicate): New procedure. * tests/store-deduplication.scm ("copy-file/deduplicate"): New test. * guix/build/store-copy.scm (populate-store): Add #:deduplicate? parameter and honor it. * tests/gexp.scm ("gexp->derivation, store copy"): Pass #:deduplicate? #f to 'populate-store'. * gnu/build/image.scm (initialize-root-partition): Pass #:deduplicate? to 'populate-store'. Pass #:deduplicate? #f to 'register-closure'. * gnu/build/vm.scm (root-partition-initializer): Likewise. * gnu/build/install.scm (populate-single-profile-directory): Pass #:deduplicate? #f to 'populate-store'. * gnu/build/linux-initrd.scm (build-initrd): Likewise. * guix/scripts/pack.scm (self-contained-tarball)[import-module?]: New procedure. [build]: Pass it as an argument to 'source-module-closure'. * guix/scripts/pack.scm (squashfs-image)[build]: Wrap in 'with-extensions'. * gnu/system/linux-initrd.scm (expression->initrd)[import-module?]: New procedure. [builder]: Pass it to 'source-module-closure'. * gnu/system/install.scm (cow-store-service-type)[import-module?]: New procedure. Pass it to 'source-module-closure'.
