Some drives will always return the number of bytes given in the
allocation_length field, but correctly report the data len in the mode
sense header. Simply ignore the excess data.

in some configurations, samba stores NTFS-ACLs in this xattr[0], so
we should backup (if we can)
altough the 'security' namespace is special (e.g. in use by
selinux, etc.) this value is normally only used by samba and we
should be able to back it up.
to restore it, the user needs at least 'CAP_SYS_ADMIN' rights, otherwise
it cannot be set

in proxmox-backup-proxy, we log and discard any errors on 'accept',
so that we can continue to server requests
in proxmox-backup-api, we just have the StaticIncoming that accepts,
which will forward any errors from the underlying TcpListener
this patch also logs and discards the errors, like in the proxy.
Otherwise it could happen that if the api-daemon has more files open
than the proxy, it will shut itself down because of a
'too many open files' error if there are many open connections
(the service should also restart on exit i think, but this is
a separate issue)

if a datastore or root is not used directly on the pool dir
(e.g. the installer creates 2 sub datasets ROOT/pbs-1), info in
/proc/self/mountinfo returns not the pool, but the path to the
dataset, which has no iostats itself in /proc/spl/kstat/zfs/
but only the pool itself
so instead of not gathering data at all, gather the info from the
underlying pool instead. if one has multiple datastores on the same
pool those rrd stats will be the same for all those datastores now
(instead of empty) similar to 'normal' directories

by using our DeflateEncoder
for this to work, we have to create wrapper reader that generates the crc32
checksum while reading.
also we need to put the target writer in an Option, so that we can take
it out of self and move it into the DeflateEncoder while writing
compressed
we can drop the internal buffer then, since that is managed by the
deflate encoder now

implements a deflate encoder that can compress anything that implements
AsyncRead + Unpin into a file with the helper 'compress'
if the inner type is a Stream, it implements Stream itself, this way
some streaming data can be streamed compressed

in commit `asyncify pxar create_archive`, we changed from a
separate thread for creating a pxar to using async code, but the
StdChannelWriter used for both pxar and catalog can block, which
may block the tokio runtime for single (and probably dual) core
environments
this patch adds a wrapper struct for any writer that implements
'std::io::Write' and wraps the write calls with 'block_in_place'
so that if called in a tokio runtime, it knows that this code
potentially blocks

of misspelled 'reserved' struct member, which where not used and
cargo build did not complain about the change, soo ...
