Attach the payload data archive as input stream to the decoder
and accessor instances for split archives.
Allows to restore contents from split archives via the
`proxmox-file-restore extract` command, by passing the metadata
archive name.

Factor out the logic to get the pxar reader into a dedicated function
so it can be reused to get the payload data archive reader instance.

... and adapt to the new reader/writer variant for encoder or
decoder/accessor to attach a dedicated payload input/output for split
pxar archives.
In preparation for look-ahead caching, where a passing around of
per-directory level encoder instances with internal references is
not feasible.
Previously, for each directory level a new encoder instance has been
generated, restricting possible implementation errors. These encoder
instances have been internally linked by references to keep track of
the state changes in a parent child relationship.
This is however not feasible when the encoder has to be passed by
mutable reference, as required by the look-ahead cache
implementation. The encoder has therefore been adapted to use a
single instance implementation with an internal stack keeping track
of the state.
Depends on the bumped pxar library version, including the patches to
attach the corresponding variant for the pxar reader/writer
instantiation.

during some tests recently I wondered why a debug log-message was not
printed, despite running with PBS_QEMU_DEBUG.
This patch sets the loglevel for the cli logger to debug if the
variable is present and not-empty (see qemu_helper.rs for the other
usage).

zfs_arc_min was raised to 32M (for linux) in zfs-commit
121b3cae742a0670d902a51bc61d49dc4a3e4445
while the current logic would still set the min_size to 32M (it's
max(32M, allmem/32), which results to 32M for memory sizes up to
1024M), setting it explicitly to the minimum makes it clear, and will
still be kept should the restore vm have more than 1G of memory at
some point.

Currently the values set for zfs_arc_min and zfs_arc_max are ignored
by the kernel:
```
Unknown kernel command line parameters... will be passed to user space
```
module parameters provided on the commandline usually need to be
prefixed with the modulename (e.g. zfs.zfs_arc_min, see [0] for a bit
on related information (the issue itself is not related)).
Paradoxically currently ZFS will print spurious warnings about
settings being ignored when they are actually set - see [1].
Booting the debug image and connecting the shell on the serial console
confirmed that the values did not seem to be set:
`grep '^c_' /proc/spl/kstat/zfs/arcstats` showed half of the memory
for c_max.

besides harmonizing versions, the only global change is that the tokio-io

pbs-buildcfg is the only one that needs to inherit the version as well, since
it stores it in the compiled crate.

Capsule it in a small QMPSock struct impl, make the usage nicer as
the caller should not have to care & keep track of the initial socket
state+details.
A send_raw and send Value method should cover most needs.

this is on top of the normal memory, and over 1.3 GB required is just
huge, sadly the commit adding this has zero details about what setups
fail and what work again with the change, so hard to tell, but any
setup that needs that much sounds like a bug in ZFS or remaining code
here.

by adding 'dynamic-memory' parameter that controls if we automatically

when a backup contains a drive with zfs on it, the default memory
size (up to 384 MiB) is often not enough to hold the zfs metadata
to improve that situation, add memory dynamically (1GiB) when a path is
requested that is on zfs. Note that the image must be started with a
kernel capable of memory hotplug.
to achieve that, we also have to add a qmp socket to the vm, so that
we can later connect and add the memory backend and dimm

if the target ist stdout, we can now specify the exact format by making use of
the new 'format' parameter of the restore daemons 'extract' api
note that extracting a pxar from a source pxar (container/host backups)
won't work currently since we would have to reencode as pxar first
