grafts: Move '%graft?' and related bindings to (guix store).
The goal is to allow (guix grafts) to use (guix gexp) without
introducing a cycle between these two modules.

* guix/grafts.scm (%graft?, call-without-grafting, without-grafting)
(set-grafting, grafting?): Move to...
* guix/store.scm: ... here.

Merge branch 'master' into core-updates
Note: this merge actually changes the 'curl' and 'python-attrs' derivations,
as part of solving caf4a7a277 and
12964df69a respectively.

4604d43c0e (gnu: gnutls@3.6.16: Fix cross-compilation.) was ignored because it
cannot currently be tested.

grafts: Cache the derivation/graft mapping for the whole session.
Partly fixes <https://bugs.gnu.org/41702>.
Reported by Lars-Dominik Braun <ldb@leibniz-psychology.org>.

Previously, 'graft-derivation' would start anew at every call.  When
creating a profile with lots of packages, it would potentially do the
same work multiple times.  The per-session cache addresses this.  It
increases the derivation-graft-cache hit rate from 77.9% to 80.1% on:

  GUIX_PROFILING="derivation-graft-cache" ./pre-inst-env \
    guix environment --ad-hoc libreoffice inkscape krita darktable -n

The effect is more visible on the pathological case below, where cache
hit rate goes from 75% to 87% and wall-clock time from 5.0s to 3.5s:

  GUIX_PROFILING="derivation-graft-cache" ./pre-inst-env \
    guix environment --ad-hoc r-learnr --search-paths

* guix/grafts.scm (%graft-cache): New variable.
(graft-derivation): Add calls to 'store-connection-cache' and
'set-store-connection-cache!'.

needlessly allocate closures.

grafts: Improve performance for derivations with many inputs.
Partly fixes <https://bugs.gnu.org/41702>.
Reported by Lars-Dominik Braun <ldb@leibniz-psychology.org>.

Previously we'd potentially traverse the same sub-graph of DEPS several
times.

With this patch, command:

  guix environment --ad-hoc r-learnr --search-paths

goes from 11.3s to 4.6s.

* guix/grafts.scm (reference-origin): Rename to...
(reference-origins): ... this.  Change 'item' parameter to 'items'.
[lookup-derivers]: New procedure.
(cumulative-grafts)[dependency-grafts]: Change 'item' to 'items' and use
'reference-origins'.
Remove 'mapm' around 'dependency-grafts' call.

grafts: Simplify access to store item references.
This is a followup to 710854304b.

This also slightly reduces the number of 'query-references' RPCs, for
instance from 176 to 166 from "guix build emacs -d".

* guix/grafts.scm (references-oracle): Remove.
(non-self-references): Remove 'references' parameter and add 'store'.
Add 'references*' procedure and use it instead of 'references'.  Adjust

grafts: Don't rely on substitute info for missing store items.
Fixes <https://bugs.gnu.org/22990>.

* guix/grafts.scm (references-oracle)[references*]: Remove call to
'substitution-oracle' and to 'references/substitutes'.  Use
'references/cached' and 'build-derivations' right away instead.

grafts: 'references-oracle' now takes a derivation input.
That way, if we end up calling 'build-derivations', we'll only build the
outputs that we really need.

* guix/grafts.scm (references-oracle): Rename 'drv' to 'input'.
[output-paths]: Remove.
Adjust accordingly.
(graft-derivation): Adjust call to 'references-oracle'.

aad086d871
grafts: Avoid 'query-valid-derivers' RPC.
Previously we'd make 502 'query-valid-derivers' RPCs for
"guix build vim -d", and after this patch, we don't do any.

Furthermore, the previous strategy was "stateful" in the sense that
'item->deriver' could return a derivation that is not the one that was
actually computed by this process, but an "equivalent" one (due to
fixed-output derivations); which one is chosen would depend on the state
of the store.

This in turn means that we'd have to call 'read-derivation-from-file' to
actually read .drv files (as opposed to getting them from
%DERIVATION-CACHE).  This is costly and doesn't work with
GUIX_DAEMON_SOCKET=ssh://….

* guix/grafts.scm (item->deriver): Remove.
(reference-origin): New procedure.
(cumulative-grafts): Use it instead of 'item->deriver'.

derivations: Introduce 'read-derivation-from-file'.
This avoids the open/fstat/close syscalls upon a cache hit that we had
with the previous idiom:

grafts: Do not pull derivation outputs not depended on.
Fixes <http://bugs.gnu.org/24886>.

Previously, the grafting derivation of, say, brdf-explorer would pull in
qt:doc even though brdf-explorer depends only on qt:out, not qt:doc.

instead of 'vhash-assq' and 'vhash-consq'.

OUTPUTS instead of (derivation-output-names drv).

'cumulative-grafts', which isn't great performance-wise.
