This makes 'guix environment PACKAGE' significantly faster when
substitutes are enabled. Before that, it would lead to many invocations
of 'guix substitute-binary', one per 'derivation-prerequisites-to-build'
call. Now, all these are replaced by a single invocation.

#:substitutable?. Remove the local 'derivation-output-paths' and
'substitutable?'.

'derivation-prerequisites-to-build'.

'derivation-path->output-path'.

return.
(guix-package): Use 'derivation->output-path'.

the result.

* tests/derivations.scm ("build derivation with 1 source"): Assert that
'derivation-file-name' returns the right thing.
* guix/derivations.scm (derivation, build-expression->derivation):

argument. New `use-substitutes?' keyword argument. Use `fold2' and
adjust to use both return values of
`derivation-prerequisites-to-build'. Display what will/would be
downloaded.

public interface.
* gnu/packages/bootstrap.scm, guix-download.in, guix/derivations.scm,
guix/packages.scm, tests/derivations.scm: Update all callers

Before it would list inputs not built, even if the outputs of the given
derivation were already available.
* guix/derivations.scm (derivation-prerequisites-to-build): Add
`outputs' keyword parameter.

and doesn't work out of the box with the statically-linked
%BOOTSTRAP-GUILE.
* guix/derivations.scm (build-expression->derivation)[source-path]: New
procedure.
[builder]: Pass only sources as references. This fixes a bug whereby

fixed-output input"): New test.
* tests/derivations.scm ("fixed-output derivation"): Add comment that
the reference to BUILDER is optional.
