to avoid the problematic open fresh datastore with fresh chunkstore
with, and that's the actual problematic part, fresh process locker.
As the latter uses posix record locks which are pretty dangreous as
they operate on a path level (not FD level) and thus closing any file
opened (even if it wasn't opened for locking at all) drops all active
locks on the same file on completely unrelated file descriptors -.-
Also, no operation wasn't exactly correct for this thing in the first
place, but we cannot use Operation::Lookup either, as we're currently
indeed using a rather stupid-simple way and *are* reading.
So until we optimize this to allow querying the AclTree if there's
any priv XYZ below a path, use the Operation::Read.

This endpoint only lists all accessible namespace, and one doesn't
necessarily needs to have permissions on the parent itself just to
have OK ACLs on deeper down NS.
So, drop the upfront check on parent but explicitly avoid leaking if
a NS exists or not, i.e., only do so if they got access on the parent
NS.

I.e., for those that only got permissions on a sub namespace and
those that onlöy got BACKUP_READ, as both they could just list and
count themselves too after all, so not exactly secret info.
The UI needs some adaptions to cope with gc-stats and usage being
optional, will be done in a next commit.

instead move the acl_path helper to BackupNamespace, and introduce a new
helper for printing a store+ns when logging/generating error messages.

these all contain the path in the error message already, so no (new)
potential for leakage..

it includes the path, which might be helpful when users are switching to
using namespaces. datastore and namespace lookup happens after, so this
doesn't leak anything.

instead of doing a manual lookup and check - this changes the returned
error slightly since check_privs will include the checked ACL path, but
that is okay here, checks are before we even lookup the namespace/store,
so no chance to leak anything.

where appropriate. these should never leak anything sensitive, as we
check privs before checking existence or existence is already known at
that point via other privileges.

syncing to a namespace only requires privileges on the namespace (and
potentially its children during execution).

the namespace is optional, but should be captured to allow ACL checks
for unprivileged non-job-owners.
also add FIXME for other job types and workers that (might) need

use the relatively new variant of ListAccessibleBackupGroups to also
allow pruning the groups that one doesn't own but has the respective
privileges on their namespace level.
This was previously handled by the API endpoint itself, which was ok
as long as only one level was looked at.

The "owner override" privs will skip the owner check completely if
the authid has a permission for any of the bitwise OR'd privs
requested on the namespace level.
The "owner and privs" are for the case where being the owner is not
enough, e.g., pruning, if set they need to match all, not just any,
on the namespace, otherwise we don't even look at the groups from the
current NS level.

This reverts commit 7a1a5d206d.
We could already cause the behavior by simply setting ignore-verified
to false, aas that flag is basically an on/off switch for even
considering outdated-after or not.
So avoid the extra logic and just make the gui use the previously
existing way.

properly encode the namespace as separate field both for manual prunes
and the job. fix the access checks as well now that the job doesn't use
the jobid as workerid anymore.
