parameters. Pass them on.

test.
We were already relying on the new version in `set-build-options', so
this patch fixes that.

server when it's recent enough.

(EXTRA_DIST): New variable.
* guix/packages.scm, distro/base.scm, tests/packages.scm: New files.
* guix/http.scm (http-fetch): Make `name' an optional argument, to match
the expectations of `package-source-derivation'.
* guix/derivations.scm (build-expression->derivation)[module-form?]: New
procedure.
[prologue]: Add any form of EXP that matches MODULE-FORM?.
[builder]: Remove any MODULE-FORM? from EXP.
* guix/build/gnu-build-system.scm (set-paths, build, check, install):
New procedures.
(unpack): Make `source' a keyword arg; add `#:allow-other-keys'.
(configure): Likewise.
(%standard-phases): New variable.
(gnu-build): Make `source', `outputs', and `inputs' keyword arguments;
add `phases' keyword argument; #:allow-other-keys; add rest arguments
`args'. Invoke each of PHASES in order within `every'.

keyword arguments. Update builder's `gnu-build' call to match the new
convention.
* guix/derivations.scm (build-expression->derivation)[builder]: Pass the
result of EXP to `exit'.
* tests/derivations.scm ("build-expression->derivation with expression
returning #f"): New test.
* guix/store.scm (current-build-output-port): New variable.
(process-stderr): Add docstring. Always return #f, except upon
%STDERR-LAST. Upon %STDERR-NEXT, write to
`current-build-output-port', not `current-error-port'.
(set-build-options): Loop until `process-stderr' returns true.
(define-operation): Likewise.
(build-derivations): Update docstring to mention that it's
synchronous.
* guix/derivations.scm (build-expression->derivation): Change to expect
INPUTS to have the form (NAME DRV-PATH SUB-DRV) or (NAME DRV-PATH),
