note, this bump happened outside the main branch as it wasn't in a
good state and there was need for bumping (log/task rotate stuff).
Cherry picking the actual bump to avoid changelog/versioning
confusion on the next one, that should again happen on the main
branch.

'export_media' can handle if the tape is in either a normal slot of the
library, or in the drive assigned to the current pool writer.
(because we need to lock the drive)
if it is, for some reason, in a different drive, the error message
'media is not online'
could be slightly confusing for a user, since it would appear in the drive list
add the 'or a differen drive' to make it clearer

it's a rather low-level tool mostly useful for debugging and some of
it is rather "dumb" (by design) anyway, e.g., it does not
transparently applies journal but really only operates on the DB
files as is (which can conflict with daemon operations).
In summary, not (yet) a tool meant for end user consumption.
Move it to examples folder to avoid compilation on packaging (we do
not ship it anyway) which allows us to move the rather expensive
proxmox-router (pulls in hyper) to the dev-dependencies section.

Because the types used inside the RRD have other requirements
than the API types:
- other serialization format
- the API may not support all RRD features

Append pending changes in a simple text based format that allows for
lockless appends as long as we stay below 4 KiB data per write.
Apply the journal every 30 minutes and on daemon startup.
Note that we do not ensure that the journal is synced, this is a
perfomance optimization we can make as the kernel defaults to
writeback in-flight data every 30s (sysctl vm/dirty_expire_centisecs)
anyway, so we lose at max half a minute of data on a crash, here one
should have in mind that we normally expose 1 minute as finest
granularity anyway, so not really much lost.
