upstream: Replace 'input-changes' field by 'inputs'.

Returning the expected list of inputs rather than changes relative to
the current package definition is less ambiguous and offers more
possibilities for further processing.

* guix/upstream.scm (<upstream-source>)[input-changes]: Remove.
[inputs]: New field.
(<upstream-input>): New record type.
* guix/upstream.scm (upstream-input-type-predicate)
(input-type-filter, upstream-source-regular-inputs)
(upstream-source-native-inputs, upstream-source-propagated-inputs): New
procedures.
(changed-inputs): Expect an <upstream-source> as its second argument.
Adjust accordingly.
* guix/import/pypi.scm (distribution-sha256): New procedure.
(maybe-inputs): Expect a list of <upstream-input>.
(compute-inputs): Rewrite to return a list of <upstream-input>.
(pypi-package-inputs, pypi-package->upstream-source): New procedures.
(make-pypi-sexp): Use it.
* guix/import/stackage.scm (latest-lts-release): Define 'cabal'.
Replace 'input-changes' field by 'inputs'.
* guix/scripts/refresh.scm (update-package): Use 'changed-inputs'
instead of 'upstream-source-input-changes'.
* tests/cran.scm ("description->package"): Adjust order of inputs.
* tests/pypi.scm (default-sha256, default-sha256/base32): New variables.
(foo-json): Add 'digests' entry.
("pypi->guix-package, no wheel"): Check HASH against DEFAULT-SHA256/BASE32.
("pypi->guix-package, wheels"): Likewise.
("pypi->guix-package, no usable requirement file."): Likewise.
("pypi->guix-package, package name contains \"-\" followed by digits"):
Likewise.
("package-latest-release"): New test.
* tests/upstream.scm (test-package-sexp): Remove.
("changed-inputs returns no changes"): Rewrite to use <upstream-source>.
(test-new-package-sexp): Remove.
("changed-inputs returns changes to plain input list"): Rewrite.
("changed-inputs returns changes to all plain input lists"): Likewise.
("changed-inputs returns changes to labelled input list")
("changed-inputs returns changes to all labelled input lists"): Remove.
* guix/import/cran.scm (maybe-inputs): Expect PACKAGE-INPUTS to be a
list of <upstream-input>.
(source-dir->dependencies): Return a list of <upstream-input>.
(vignette-builders): Likewise.
(uri-helper, cran-package-source-url)
(cran-package-propagated-inputs, cran-package-inputs): New procedures.
(description->package): Use them instead of local definitions.
(latest-cran-release): Replace 'input-changes' field by 'inputs'.
(latest-bioconductor-release): Likewise.
(format-inputs): Remove.
* guix/import/hackage.scm (cabal-package-inputs): New procedure.
(hackage-module->sexp): Use it.
[maybe-inputs]: Expect a list of <upstream-input>.
