gexp: Preserve source location for #~ and #$ read extensions.
Read hash extensions preserve source location info as source properties
on their result.  However, in Guile 3.0.8, that location would be
dismissed, leading 'local-file' to fail to resolve file names relative
to the source directory.

Fixes <https://issues.guix.gnu.org/54003>.
Reported by Aleksandr Vityazev <avityazev@posteo.org>.

* guix/gexp.scm <eval-when> [read-syntax-redefined?, read-procedure]

[read-ungexp]: Adjust to expect either sexps or syntax objects.
[read-gexp]: Call 'read-procedure'.

gexp: 'computed-file' always uses a native Guile.
Fixes a regression whereby, when cross-compiling, 'computed-file' would
use a cross-compiled Guile as its builder, which would fail to run.

Regression introduced in af57d1bf6c (the
problem had always been there but was hidden before behind the (not guile)
condition.)

* guix/gexp.scm (computed-file-compiler): For 'guile', pass #:target #f.
* tests/gexp.scm ("lower-object, computed-file, #:target"): New test.

gexp: Leave grafting as is when lowering allowed/disallowed references.
Fixes <https://issues.guix.gnu.org/50676>.
Reported by Mathieu Othacehe <othacehe@gnu.org>.

Commit a779363b6a was partially incorrect:
references passed to #:allowed-references or #:references-graphs *can*
be lowered as references to grafted elements.  This is for example the
case when doing:

  (computed-file "partition.img" exp
                  #:options `(#:references-graphs ,inputs))

Here INPUTS must be lowered as a reference to suitably grafted elements.
Failing to do that, the reference graph will not match the actual
INPUTS.

However, when building a package, those references must indeed refer
only to ungrafted packages.  This commit preserves that by having build
systems pass #:graft? #f.

* guix/gexp.scm (lower-reference-graphs, lower-references): Remove uses
of 'without-grafting'.  This reverts
a779363b6a.

gexp: #:references-graphs refers to non-native derivations.
Fixes a regression introduced in
c6d6aee6659acb293eb33f498fdac3b47a19a48, where #:reference-graphs would

This would notably break the compilation of systems using a childhurd,
because they would attempt to build the 'hurd' package natively.

gexp: 'imported-files' no longer creates a derivation by default.
* guix/gexp.scm (gexp->derivation): Add #:import-creates-derivation?.
Pass #:derivation? to 'imported-modules' and 'compiled-modules'.  In -L
argument, check whether MODULES is a derivation.
(%not-slash): New variable.
(file-mapping->tree): New procedure.
(imported-files): Rename to...
(imported-files/derivation): ... this.
(imported-files): New procedure.  Rewrite in terms of
'interned-file-tree' when possible; add #:derivation? parameter.
(imported-modules, compiled-modules): Add #:derivation? parameter and
pass it to 'imported-files'.
* guix/packages.scm (patch-and-repack): Pass
 #:import-creates-derivation? to 'gexp->derivation'.
* tests/gexp.scm ("imported-files"): Adjust to no longer expect a
derivation.

store-copy: 'read-reference-graph' returns a list of records.
The previous implementation of 'read-reference-graph' was good enough
for many use cases, but it discarded the graph structure, which is
useful information in some cases.

* guix/build/store-copy.scm (<store-info>): New record type.
(read-reference-graph): Rewrite to return a list of <store-info>.
(closure-size, populate-store): Adjust accordingly.
* gnu/services/base.scm (references-file): Adjust accordingly.
* gnu/system/vm.scm (system-docker-image): Likewise.
* guix/scripts/pack.scm (squashfs-image, docker-image): Likewise.
* tests/gexp.scm ("gexp->derivation #:references-graphs"): Likewise.
