database: Make 'register-items' transactional.
* guix/store/database.scm (SQLITE_BUSY, register-output-sql): New variables.
(add-references): Don't try finalizing after each use, only after all the
uses (otherwise a finalized statement would be used if #:cache? was #f).
(call-with-transaction): New procedure.
(register-items): Use call-with-transaction to prevent broken intermediate
states from being visible.

* .dir-locals.el (call-with-transaction): indent it.

Ludovic Courtès bdf860c2e9
database: Use "write-ahead log" mode and set a long "busy timeout".
This should avoid "database is locked" errors when there's a lot of
concurrency, for instance when offloading simultaneously a lot of
builds.

* guix/store/database.scm (call-with-database): Add two 'sqlite-exec'
calls to set 'journal_mode' and 'busy_timeout'.

database: Register each store item only once.
Fixes <https://bugs.gnu.org/32600>.
Reported by Leo Famulari.

* guix/store/database.scm (register-items): Check whether TO-REGISTER is
in DB by calling 'path-id',  and skip the reset-timestamps,
registration, and deduplication phases when it is.

database: 'register-items' shows a progress bar.

Ludovic Courtès e475211869
database: Reset timestamps to one second after the Epoch.
Previously, store items registered in the database by this code (for
instance, store items retrieved by 'guix offload' and passed to
'restore-file-set') would have an mtime of 0 instead of 1.

This would cause problems for things like .go files: Guile would
consider them to be older than the corresponding .scm file, and
consequently it would ignore them and possibly use another (incorrect)
.go file.

Reported by Ricardo Wurmus.

* guix/store/database.scm (reset-timestamps): Pass 1, not 0, to
'utime'.
* tests/store-database.scm ("register-path"): Check the mtime of FILE
and REF.
