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

shows all tapes with the relevant info
* which pool it belongs to
* what backups are on it
* which media-set
* location
* etc.
This is very rough, and maybe not the best way to display this information.
It may make sense to reverse the tree, i.e. having pools at top-level,
then media-sets, then tapes, then snapshots..

* Drives
* Changers
* Media Pools
* Labeling Media
* Making new Tape Backups

this check is not perfect since there are often multiple device
nodes per drive/changer, but from the scan api we should return always
the same, so for an api user this should be enough

so that an api user can get the drives belonging to a changer
without having to parse the config listing themselves

similar to the changers, create a listing at /tape/drive and put
the specific api calls below that
move the scan api call up one level
remove the status info from the config listing

so that an api user can see which drive belongs to which drivenum of a changer
for ones with multiple drives
