system: 'init' does not recompute the hash of each store item.
Fixes <https://bugs.gnu.org/44760>.
Previously, the 'register-path' call would re-traverse ITEM to compute
its nar hash, even though that hash is already known in the initial
store. This patch also avoids repeated opening/closing of the
database.
* guix/store/database.scm (call-with-database): Export.
* guix/scripts/system.scm (copy-item): Add 'db' parameter. Call
'sqlite-register' instead of 'register-path'.
(copy-closure): Remove redundant call to 'references*'. Call
'call-with-database' and pass the database to 'copy-item'.
