via HTTP2/backup reader protocol. they already could do so via the plain
HTTP download-file/.. API calls that the GUI uses, but the reader
environment required READ permission on the whole datastore instead of
just BACKUP on the backup group itself.

a reader connection should not be allowed to read arbitrary chunks in
the datastore, but only those that were previously registered by opening
the corresponding index files.
this mechanism is needed to allow unprivileged users (that don't have
full READ permissions on the whole datastore) access to their own
backups via a reader environment.

filtered by those they are privileged enough to read individually. this
allows such users to configure prune/GC schedules via the GUI (the API
already allowed it previously).
permission-wise, a user with this privilege can already:
- list all stores they have access to (returns just name/comment)
- read the config of each store they have access to individually
(returns full config of that datastore + digest of whole config)
but combines them to
- read configs of all datastores they have access to (returns full
config of those datastores + digest of whole config)
user that have AUDIT on just /datastore without propagate can now no
longer read all configurations (but this could be added it back, it just
seems to make little sense to me).

for encrypted chunks this is currently not possible, as we need the key

Signed-off-by: Fabian Grünbichler <f.gruenbichler@proxmox.com>
regular chunks are only decoded when their contents are accessed, in
which case we need to have the key anyway and want to verify the digest.
for blobs we need to verify beforehand, since their checksums are always
calculated based on their raw content, and stored in the manifest.
manifests are also stored as blobs, but don't have a digest in the
traditional sense (they might have a signature covering parts of their
contents, but that is verified already when loading the manifest).
this commit does not cover pull/sync code which copies blobs and chunks
as-is without decoding them.
