414c23facb fix #3060:: improve get_owner error handling
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.

e1c1533790 fix #3039: use the same ID regex for info and api
in the api we use PROXMOX_SAFE_ID_REGEX for backup ids, but here
(where we use it to list them) we use a local regex

since the first is a superset of the one used here, simply extend
the local one

5499bd3dee fix #2998: encode mtime as i64 instead of u64
saves files mtime as i64 instead of u64 which enables backup of
files with negative mtime

the catalog_decode_i64 is compatible to encoded u64 values (if < 2^63)
but not reverse, so all "old" catalogs can be read with the new
decoder, but catalogs that contain negative mtimes will decode wrongly
on older clients

also remove the arbitrary maximum value of 2^63 - 1 for
encode_u64 (we just use up to 10 bytes now) and correctly
decode them and update the comments accordingly

adds also test for i64 encode/decode and for compatibility between
u64 encode and i64 decode

b4b14dc16e do_verification_job: fix "never-reverify" and refactor/comment
commit a4915dfc2b made a wrong fix, as
it did not observed that the last expressions was done under the
invariant that we had a last verification result, because if none
could be loaded we already returned true (include).

It thus broke the case for "never re-verify", which is important when
using multiple schedules, a more high frequent one for new,
unverified snapshots, and a low frequency to re-verify older snapshots,
e.g., monthly.

Fix this case again, rework the code to avoid this easy to oversee
invariant. Use a nested match to better express the implication of
each setting, and add some comments.

Snapshot deletion also acquires the lock, so it cannot interfere with an

f6b1d1cc66 don't require WorkerTask in backup/
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.

fe0efb25e8 backup: index readers: drop useless shared lock
This is only acquired in those two methods, both as shared. So it has
no use.

It seems, that it was planned in the past that the index deletion
should take the exclusive, while read and write takes the shared
flock on the index, as one can guess from the lock comments in commit
0465218953

But then later, in commit c8ec450e37)
the documented semantics where changed to use a temp file and do an
atomic rename instead for atomicity.

The reader shared flock on the index file was done inbetween,
probably as preparatory step, but was not removed again when strategy
was changed to using the file rename instead.

Do so now, to avoid confusion of readers and a useless flock.
