Switch to Guile-Gcrypt.
This removes (guix hash) and (guix pk-crypto), which now live as part of Guile-Gcrypt (version 0.1.0.) * guix/gcrypt.scm, guix/hash.scm, guix/pk-crypto.scm, tests/hash.scm, tests/pk-crypto.scm: Remove. * configure.ac: Test for Guile-Gcrypt. Remove LIBGCRYPT and LIBGCRYPT_LIBDIR assignments. * m4/guix.m4 (GUIX_ASSERT_LIBGCRYPT_USABLE): Remove. * README: Add Guile-Gcrypt to the dependencies; move libgcrypt as "required unless --disable-daemon". * doc/guix.texi (Requirements): Likewise. * gnu/packages/bash.scm, guix/derivations.scm, guix/docker.scm, guix/git.scm, guix/http-client.scm, guix/import/cpan.scm, guix/import/cran.scm, guix/import/crate.scm, guix/import/elpa.scm, guix/import/gnu.scm, guix/import/hackage.scm, guix/import/texlive.scm, guix/import/utils.scm, guix/nar.scm, guix/pki.scm, guix/scripts/archive.scm, guix/scripts/authenticate.scm, guix/scripts/download.scm, guix/scripts/hash.scm, guix/scripts/pack.scm, guix/scripts/publish.scm, guix/scripts/refresh.scm, guix/scripts/substitute.scm, guix/store.scm, guix/store/deduplication.scm, guix/tests.scm, tests/base32.scm, tests/builders.scm, tests/challenge.scm, tests/cpan.scm, tests/crate.scm, tests/derivations.scm, tests/gem.scm, tests/nar.scm, tests/opam.scm, tests/pki.scm, tests/publish.scm, tests/pypi.scm, tests/store-deduplication.scm, tests/store.scm, tests/substitute.scm: Adjust imports. * gnu/system/vm.scm: Likewise. (guile-sqlite3&co): Rename to... (gcrypt-sqlite3&co): ... this. Add GUILE-GCRYPT. (expression->derivation-in-linux-vm)[config]: Remove. (iso9660-image)[config]: Remove. (qemu-image)[config]: Remove. (system-docker-image)[config]: Remove. * guix/scripts/pack.scm: Adjust imports. (guile-sqlite3&co): Rename to... (gcrypt-sqlite3&co): ... this. Add GUILE-GCRYPT. (self-contained-tarball)[build]: Call 'make-config.scm' without #:libgcrypt argument. (squashfs-image)[libgcrypt]: Remove. [build]: Call 'make-config.scm' without #:libgcrypt. (docker-image)[config, json]: Remove. [build]: Add GUILE-GCRYPT to the extensions Remove (guix config) from the imported modules. * guix/self.scm (specification->package): Remove "libgcrypt", add "guile-gcrypt". (compiled-guix): Remove #:libgcrypt. [guile-gcrypt]: New variable. [dependencies]: Add it. [*core-modules*]: Remove #:libgcrypt from 'make-config.scm' call. Add #:extensions. [*config*]: Remove #:libgcrypt from 'make-config.scm' call. (%dependency-variables): Remove %libgcrypt. (make-config.scm): Remove #:libgcrypt. * build-aux/build-self.scm (guile-gcrypt): New variable. (make-config.scm): Remove #:libgcrypt. (build-program)[fake-gcrypt-hash]: New variable. Add (gcrypt hash) to the imported modules. Adjust load path assignments. * gnu/packages/package-management.scm (guix)[propagated-inputs]: Add GUILE-GCRYPT. [arguments]: In 'wrap-program' phase, add GUILE-GCRYPT to the search path.
