maint: update-guix-package: Prevent accidentally breaking guix pull.
Fixes <https://issues.guix.gnu.org/43893>.

This changes the 'update-guix-package' tool so that it:

1. Always uses a clean checkout to compute the hash of the updated 'guix'
package.
2. Ensures the commit used in the updated 'guix' package definition has already
been pushed upstream.

* build-aux/update-guix-package.scm (%savannah-guix-git-repo-push-url): New
variable.
(with-input-pipe-to-string, with-temporary-git-worktree): New syntaxes.
(find-origin-remote, git-add-worktree): New procedures.
(commit-already-pushed?): New predicate.
(main): Check the commit used has already been pushed upstream and compute the
hash from a clean checkout.
* doc/contributing.texi (Updating the Guix Package): Document it.
* .dir-locals.el (scheme-mode): Fix indentation of with-temporary-git-worktree.

deduplication: pass store directory to replace-with-link.
This causes with-writable-file to take into consideration the actual store
being used, as passed to 'deduplicate', rather than
whatever (%store-directory) may return.

* guix/store/deduplication.scm (replace-with-link): new keyword argument
  'store'.  Pass to with-writable-file.
  (with-writable-file, call-with-writable-file): new store argument.
  (deduplicate): pass store to replace-with-link.

database: separate transaction-handling and retry-handling.
Previously call-with-transaction would both retry when SQLITE_BUSY errors were
thrown and do what its name suggested (start and rollback/commit a
transaction).  This changes it to do only what its name implies, which
simplifies its implementation.  Retrying is provided by the new
call-with-SQLITE_BUSY-retrying procedure.

* guix/store/database.scm (call-with-transaction): no longer restarts, new
  #:restartable? argument controls whether "begin" or "begin immediate" is
  used.
  (call-with-SQLITE_BUSY-retrying, call-with-retrying-transaction,
  call-with-retrying-savepoint): new procedures.
  (register-items): use call-with-retrying-transaction to preserve old
  behavior.

* .dir-locals.el (call-with-retrying-transaction,
  call-with-retrying-savepoint): add indentation information.

database: ensure update-or-insert is run within a transaction
update-or-insert can break if an insert occurs between when it decides whether
to update or insert and when it actually performs that operation.  Putting the
check and the update/insert operation in the same transaction ensures that the
update/insert will only succeed if no other write has occurred in the middle.

* guix/store/database.scm (call-with-savepoint): new procedure.
  (update-or-insert): use call-with-savepoint to ensure the read and the
  insert/update occur within the same transaction.

database: rewrite query procedures in terms of with-statement.
Most of our queries would fail to finalize their statements properly if sqlite
returned an error during their execution.  This resolves that, and also makes
them somewhat more concise as a side-effect.

This also makes some small changes to improve certain queries where behavior
was strange or overly verbose.

* guix/store/database.scm (call-with-statement): new procedure.
  (with-statement): new macro.
  (last-insert-row-id, path-id, update-or-insert, add-references): rewrite to
  use with-statement.
  (update-or-insert): factor last-insert-row-id out of the end of both
  branches.
  (add-references): remove pointless last-insert-row-id call.

* .dir-locals.el (with-statement): add indenting information.
