4921a411ad backup/datastore: refactor chunk inode sorting to the datastore
so that we can reuse that information

the removal of the adding to the corrupted list is ok, since
'get_chunks_in_order' returns them at the end of the list
and we do the same if the loading fails later in 'verify_index_chunks'
so we still mark them corrupt
(assuming that the load will fail if the stat does)

10351f7075 backup: add AsyncRead/Seek to CachedChunkReader
Implemented as a seperate struct SeekableCachedChunkReader that contains
the original as an Arc, since the read_at future captures the
CachedChunkReader, which would otherwise not work with the lifetimes
required by AsyncRead. This is also the reason we cannot use a shared
read buffer and have to allocate a new one for every read. It also means
that the struct items required for AsyncRead/Seek do not need to be
included in a regular CachedChunkReader.

This is intended as a replacement for AsyncIndexReader, so we have less
code duplication and can utilize the LRU cache there too (even though
actual request concurrency is not supported in these traits).

062cf75cdf proxmox-backup-proxy: fix leftover references on datastore removal
when we remove a datastore via api/cli, the proxy
has sometimes leftover references to that datastore in its
DATASTORE_MAP which includes an open filehandle on the
'.lock' file

this prevents unmounting/exporting the datastore even after removal,
only a reload/restart of the proxy did help

add a command to our command socket, which removes all non
configured datastores from the map, dropping the open filehandle

26af61debc backup verify: re-check if we can skip a chunk in the actual verify loop
Fixes a non-negligible performance regression from commit
7f394c807b

While we skip known-verified chunks in the stat-and-inode-sort loop,
those are only the ones from previous indexes. If there's a repeated
chunk in one index they would get re-verified more often as required.

So, add the check again explicitly to the read+verify loop.

7f394c807b backup/verify: improve speed by sorting chunks by inode
before reading the chunks from disk in the order of the index file,
stat them first and sort them by inode number.

this can have a very positive impact on read speed on spinning disks,
even with the additional stat'ing of the chunks.

memory footprint should be tolerable, for 1_000_000 chunks
we need about ~16MiB of memory (Vec of 64bit position + 64bit inode)
(assuming 4MiB Chunks, such an index would reference 4TiB of data)

two small benchmarks (single spinner, ext4) here showed an improvement from
~430 seconds to ~330 seconds for a 32GiB fixed index
and from
~160 seconds to ~120 seconds for a 10GiB dynamic index

1399c592d1 garbage_collection: only ignore 'missing chunk' errors
with the fix for #2909 (improving handling missing chunks), we
changed from bailing to warning during a garbage collection when
updating the atime of a chunk.

but, updating the atime can not only fail when the chunk is missing,
but also on other occasions, e.g. no permissions or more importantly,
no space left on the device. in that case, the atime of a valid and used
chunk cannot be updated, and the second sweep of the gc will remove that chunk.
[0] is a real world example of that happening.

instead, only warn on really missin chunks, and bail on all other
errors.

6b127e6ea0 fix #3139: add key fingerprint to manifest
if the manifest is signed/the contained archives/blobs are encrypted.
stored in 'unprotected' area, since there is already a strong binding
between key and manifest via the signature, and this avoids breaking
backwards compatibility for a simple usability improvement.

fd19256470 gc: treat .bad files like regular chunks
Simplify the phase 2 code by treating .bad files just like regular
chunks, with the exception of stat logging.

To facilitate, we need to touch .bad files in phase 1. We only do this
under the condition that 1) the original chunk is missing (as before),
and 2) the original chunk is still referenced somewhere (since the code
lives in the error handler for a failed chunk touch, it only gets called
for chunks we expect to be there, i.e. ones that are referenced).

Untouched they will then be cleaned up after 24 hours (or after the last
longer-running task finishes).

Reason 2) is also a fix for .bad files not being cleaned up at all if
the original is no longer referenced anywhere (e.g. a user deleting all
snapshots after seeing some corrupt chunks appear).

cond_touch_path is introduced to touch arbitrary paths in the chunk
store with the same logic as touching chunks.

by listing groups first, then filtering, then listing group snapshots.

this cuts down the number of openat/getdirents calls for users that just

log invalid owners to system log, and continue with next group just as
if permission checks fail for the following operations:
- verify store with limited permissions
- list store groups
- list store snapshots

all other call sites either handle it correctly already (sync/pull), or
operate on a single group/snapshot and can bubble up the error.
