Backport of commit 0bd9c87010
When re-opening a datastore due to the cached entry being stale
(only on verify-new config change). On datastore open the chunk store
was also re-opened, which in turn creates a new ProcessLocker,
loosing any existing shared lock which can cause conflicts between
long running (24h+) backups and GC.
To fix this, reuse the existing ChunkStore, and thus its
ProcessLocker, when creating a up-to-date datastore instance on
lookup, since only the datastore config should be reloaded. This is
fine as the ChunkStore path is not updatable over our API.
Note that this is a precaution backport, the underlying issue this
fixes is relatively unlikely to cause any trouble in the 1.x branch
due to not often re-opening the datastore.

this fixes the leaked memory for the cache, as we had only pointers
in the map/list which were freed, not the underlying chunks
moves the 'clear' implementation out of the trait bounds so that
Drop can reuse it
this is used e.g. for file download from a pxar

send_command serializes everything so it cannot be used to send a
raw, optimized command. Normally that means we get an error like
> 'unable to parse parameters (expected json object)'
when used that way.
Switch over to send_raw_command which does not re-serializes the
command.

This lock is held during VM startup, so that multiple calls will not
start VMs twice. But this means that the timeout needs to incorporate
the time it might take a VM to boot, so increase it quite a bit.
This could previously lead to "interrupted system call" errors when
accessing backups with many disks.

During startup most of the stuff is happening in milliseconds (or
less), so the timestamp granularity of seconds made it hard to tell
if the previous command required 990ms or 1ms, which is quite the
difference in the restore daemon context.
Using micros seems not to bring too much additional information, a
millisecond is already an ok lower time resolution for logging, so
switch only to millis for now.

fixes file restore again.
The new Memcom tracking file lives in `/run/proxmox-backup` and is
always created on REST interaction, as CachedUserInfo uses it to
efficiently track config changes, and such a cache is used in each
REST handle_request.
Further, the Memcom infra expects the base run PBS dir to exists
already, which is an OK assumption to have, but in the file-restore
daemon we have a significantly more minimal environment, and the run
dir was simply not required there, even /run isn't a tmpfs yet.

We send it already to the user via the response body, but the
log_response does not has, nor wants to have FWIW, access to the
async body stream, so pass it through the ErrorMessageExtension
mechanism like we do else where.
Note that this is not only useful for PBS API proxy/daemon but also
the REST server of the file-restore daemon running inside the restore
VM, and it really is *very* helpful to debug things there..

According to crypt(3):
"crypt places its result in a static storage area, which will be
overwritten by subsequent calls to crypt. It is not safe to call crypt
from multiple threads simultaneously."
This means that multiple login calls as a PBS-realm user can collide and
produce intermittent authentication failures. A visible case is for
file-restore, where VMs with many disks lead to just as many auth-calls
at the same time, as the GUI tries to expand each tree element on load.
Instead, use the thread-safe variant 'crypt_r', which places the result
into a pre-allocated buffer of type 'crypt_data'. The C struct is laid
out according to 'lib/crypt.h.in' and the man page mentioned above.
Use the opportunity and make both arguments to the rust 'crypt' function
take a &[u8].

we try to load the correct media in a loop until we find the correct tape.
when encountering an error or wrong tape, we want to log that (and send
an email if one is set) that requests the correct tape.
while trying to avoid printing the same errors more than once in a row,
we had at least one case (starting with an empty tape in the drive)
which would not print/send any tape request.
reworking that code to use a custom 'TapeRequest' enum, which contains
the state + error message, and a helper that prints and sends an email
when the state changes
this reduces the change check/log to a single variable, instead of 4
(tried, last_media_uuid, last_error, failure_reason)

we have a static list of filesystems and their capabilities regarding
file attributes and fs features (e.g. sockets/fifos/etc) which also
includes xattrs,acls and fcaps
if we did not know a filesystem by its magic number (for example cephfs),
we did not even attempt to read xattrs, etc.
this patch adds those flags by default to unknown filesystems, and
removes them when we encounter EOPNOTSUPP (to remove the number
of syscalls)
with this, we should be able to catch xattrs/acls/fcaps on all
(unknown) fs types that support them

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).
