For proxmox packages it works the same way as PVE, by retrieving the
changelog URL and issuing a HTTP GET to it, forwarding the output to the
client. As this is only supposed to be a workaround removed in the
future, a simple block_on is used to avoid async.
For debian packages we can simply call 'apt-get changelog' and forward
it's output.

As always, libapt is mocking us with complexity, but we can get the
approximate result we want by retrieving dependencies of all
to-be-updated packages and then seeing if they are missing.
If they are, we assume they will be installed.
For this, query_detailed_info is extended to allow reading details for
non-installed packages, and this is also exposed in
list_installed_apt_packages via 'all_versions_for'. This is necessary so
we can retrieve changelogs for such packages.
Note that we cannot retrieve all that information all the time, as
querying details for packages that aren't installed takes a rather long
time.

To cater to the paranoid, a new datastore-wide setting "verify-new" is
introduced. When set, a verify job will be spawned right after a new

Avoid races when updating manifest data by flocking a lock file.
update_manifest is used to ensure updates always happen with the lock
held.
Snapshot deletion also acquires the lock, so it cannot interfere with an
outstanding manifest write.

Also makes further changes to the method simpler.

A removal can fail if the snapshot is already gone (this is fine, our
job is done either way) or we couldn't get a lock (also fine, it can't
be removed then, just warn the user so he knows what happened and why it
wasn't removed) - keep going either way.

To untangle the server code from the actual backup
implementation.
It would be ideal if the whole backup/ dir could become its
own crate with minimal dependencies, certainly without
depending on the actual api server. That would then also be
used more easily to create forensic tools for all the data
file types we have in the backup repositories.

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.

Previously only Datastore.Modify was required for creating a new
datastore.
But, that endpoint allows one to pass an arbitrary path, of which all
parent directories will be created, this can allow any user with the
"Datastore Admin" role on "/datastores" to do some damage to the
system. Further, it is effectively a side channel for revealing the
systems directory structure through educated guessing and error
handling.
Add a new privilege "Datastore.Allocate" which, for now, is used
specifically for the create datastore API endpoint.
Add it only to the "Admin" role.

This can slow things down by a lot on setups with (relatively) high
seek time, in the order of doubling the backup times if cache isn't
populated with the last backups chunk inode info.
Effectively there's nothing known this protects us from in the
codebase. The only thing which was theorized about was the case
where a really long running backup job (over 24 hours) is still
running and writing new chunks, not indexed yet anywhere, then an
update (or manual action) triggers a reload of the proxy. There was
some theory that then a GC in the new daemon would not know about the
oldest writer in the old one, and thus use a less strict atime limit
for chunk sweeping - opening up a window for deleting chunks from the
long running backup.
But, this simply cannot happen as we have a per datastore process
wide flock, which is acquired shared by backup jobs and exclusive by
GC. In the same process GC and backup can both get it, as it has a
process locking granularity. If there's an old daemon with a writer,
that also has the lock open shared, and so no GC in the new process
can get exclusive access to it.
So, with that confirmed we have no need for a "half-assed"
verification in the backup finish step. Rather, we plan to add an
opt-in "full verify each backup on finish" option (see #2988)
