("add-to-store, recursive"): New test.
tests: Don't hard-code the system type.
* tests/derivations.scm (%current-system): New variable. Replace
occurrences of "x86_64-linux" by %CURRENT-SYSTEM.
Add multiple-output support to `build-expression->derivation'.
* guix/derivations.scm (build-expression->derivation): Add `outputs'
keyword parameter; pass it to `derivation'. Define `%outputs' in the
prologue.
* tests/derivations.scm ("build-expression->derivation with two
outputs"): New test.
Add `derivation' test for multiple-output derivations.
* tests/derivations.scm ("multiple-output derivation"): New test.
Sort environment variables alphabetically in `derivation'.
* guix/derivations.scm (derivation)[env-vars-with-empty-outputs]: Sort
the result alphabetically.
* tests/derivations.scm ("build derivation with 1 source"): Add
environment variables.
Add support for fixed-output derivations in `build-expression->derivation'.
* guix/derivations.scm (build-expression->derivation): Pass HASH and
HASH-ALGO to `derivation'.
* tests/derivations.scm ("build-expression->derivation for fixed-output
derivation"): New test.
Add support for fixed-output derivations.
* guix/derivations.scm (read-derivation)[outputs->alist]: For
fixed-outputs, convert HASH with `base16-string->bytevector'.
(write-derivation): Likewise, convert HASH-ALGO to a string and HASH
to a base16 string.
(derivation-hash): Expect HASH to be a bytevector, not a string;
convert HASH with `bytevector->base16-string'.
* tests/derivations.scm ("fixed-output derivation"): New test.
Add `base16-string->bytevector'.
* guix/utils.scm (base16-string->bytevector): New procedure.

bytevector-quintet-set-right!, base32-string-unfold,
base32-string-unfold-right, make-base32-string->bytevector,
base32-string->bytevector, nix-base32-string->bytevector): New
procedures.

(build-expression->derivation): New procedure.

"build-expression->derivation with one input"): New tests.
Allow derivations with input derivations.
* guix/derivations.scm (derivation-path->output-path): New procedure.
(derivation-hash): Call `memoize'. In the fixed-output case, convert
HASH-ALGO to a string. In the other case, sort inputs in the
alphabetical order of their hex hash. For inputs with no sub-drvs,
add "out" as the sub-drv.
* guix/utils.scm (%nixpkgs-directory): New parameter.
(nixpkgs-derivation, memoize): New procedures.
* tests/derivations.scm ("build derivation with 1 source"): Remove
useless shebang.
(%coreutils): New variable.
("build derivation with coreutils"): New test.
Fix the order of environment variables in `derivation'.
* guix/derivations.scm (derivation)[env-vars-with-empty-outputs]:
Prepend new environment variables (as expected by Nix), and add them
to E.
SRFI-64: Remove use of (ice-9 syntax-case).
* srfi/srfi-64.upstream.scm [guile]: Remove use of (ice-9 syntax-case).
tests: Look up `test.drv' using `search-path'.
* tests/derivations.scm ("parse & export"): Use `search-path' to find
`test.drv'.
Test the `build-derivations' operation.
* guix/derivations.scm (derivation): Return DRV as a second value.

Fix `bytevector->nix-base32-string'.
* guix/utils.scm (bytevector-quintet-ref-right,
bytevector-quintet-fold): New procedures.
(bytevector-quintet-fold-right): Add `quintet-fold' parameter; use it
instead of `bytevector-quintet-fold'.
