our patches got applied upstream, and a release was cut, so we no longer
need to depend on a manually patched version here.

with the fix for #2909 (improving handling missing chunks), we
changed from bailing to warning during a garbage collection when
updating the atime of a chunk.
but, updating the atime can not only fail when the chunk is missing,
but also on other occasions, e.g. no permissions or more importantly,
no space left on the device. in that case, the atime of a valid and used
chunk cannot be updated, and the second sweep of the gc will remove that chunk.
[0] is a real world example of that happening.
instead, only warn on really missin chunks, and bail on all other
errors.

when executing this code as non-root, we use sg-tape-cmd (a setuid binary)
to execute various ioctls on the tape device
we give the command the open tape device fd as stdin, but did not
dup it, so the std::process:Stdio handle closed it on drop,
which let subsequent operation on that file fail (since it was closed)
fix it by dup'ing it before giving it to the command, and also refactor
the calling code, so that we do not forget to do this

we did this for 'mtx', but missed it for the sg_pt_changer code
refactor it into the MtxStatus strut, and call it from both
code paths

mostly typical CRUD interface for managing drives, with an
additional actioncolumn containing some useful actions, e.g.
* reading the label
* show volume-statistics
* show the status
* label the inserted tape

this lets the users manage changers and lets them view the status of one
by having an overview of:
* slots for tapes
* import/export slots
* drives
lets the user:
* barcode-label all the tapes in the library
* move tapes between slots, into/out of drives
* show some basic info when a tape is loaded into a drive
* show the status of a drive
* clean a drive
