Move record utilities to (guix records).
* guix/utils.scm (define-record-type*): Move to... * guix/records.scm: ... here. New file. * guix/build-system.scm, guix/packages.scm: Use it. * guix/gnu-maintenance.scm: Likewise. (official-gnu-packages)[alist->record]: Remove. * guix/scripts/substitute-binary.scm: Likewise. (alist->record, object->fields): Remove. * tests/utils.scm ("define-record-type*", "define-record-type* with letrec* behavior", "define-record-type* & inherit", "define-record-type* & inherit & letrec* behavior", "define-record-type* & thunked", "define-record-type* & thunked & default", "define-record-type* & thunked & inherited"): Move to... * tests/records.scm: ... here. New file.
