tests: Avoid 'delete-paths' calls for 'derivation-prerequisites-to-build'.
* tests/derivations.scm ("derivation-prerequisites-to-build when outputs
already present"): Insert random text in BUILDER, and remove two calls
to 'delete-paths'.  Use 'derivation->output-path' for INPUT-PATH instead
of an old idiom.

import: hackage: Handle Hackage revisions.
Hackage packages can have metadata revisions (Cabal file only) that are
not reflected in the source archive.  The Haskell build system has
support for this, but until now the Hackage importer would create a
package based on the revised Cabal file which would then build using the
old Cabal file.

Fixes <https://bugs.gnu.org/35750>.

* guix/import/cabal.scm (<cabal-package>): Add 'revision' field.
(eval-cabal): Parse 'x-revision:' property.
* guix/import/hackage.scm (read-cabal-and-hash): New procedure.
(hackage-fetch-and-hash): New procedure.
(hackage-fetch): Rewrite using 'hackage-fetch-and-hash'.
(hackage-module->sexp): Add 'cabal-hash' argument and use it to populate
the '#:cabal-revision' argument.
(hackage->guix-package): Use the new '-and-hash' functions to get the
hash of the Cabal file and pass it to 'hackage-module->sexp'.
* guix/tests/hackage.scm: Test import of Cabal file revision.

discovery: 'all-modules' returns modules in path order.
A particular effect of this is that if there are ambiguous
packages in a directory specified with `-L module_dir` and the

or `guix package -i`.)

guix build: '--with-commit' makes recursive checkouts.
This was an omission from commit
024a6bfba9.

* guix/scripts/build.scm (transform-package-source-commit): Add
'recursive?' field to SOURCE.
* tests/scripts-build.scm ("options->transformation, with-branch")
("options->transformation, with-commit"): New tests.

guix build: Transformation options match packages by spec.
This allows us to combine several transformations on a given package, in
particular '--with-git-url' and '--with-branch'.

Previously transformations would ignore each other since they would all
take (specification->package SOURCE) as their replacement source,
compare it by identity, which doesn't work if a previous transformation
has already changed SOURCE.

* guix/scripts/build.scm (evaluate-replacement-specs): Adjust to produce
an alist as expected by 'package-input-rewriting/spec', with a package
spec as the first element of each pair.
(evaluate-git-replacement-specs): Likewise.
(transform-package-inputs):  Adjust accordingly and use
'package-input-rewriting/spec'.
(transform-package-inputs/graft): Likewise.
(transform-package-source-branch, transform-package-source-commit): Use
'package-input-rewriting/spec'.
(transform-package-source-git-url): Likewise, and adjust the
REPLACEMENTS alist accordingly.
(options->transformation): Iterate over OPTS instead of over
%TRANSFORMATIONS.  Invoke transformations one by one.
* tests/scripts-build.scm ("options->transformation, with-input"):
Adjust test to compare packages by name rather than by identity.
("options->transformation, with-git-url + with-branch"): New test.
