42b010174e tape: changer: handle invalid descriptor data from library in status page
We get the descriptor length from the library and use that in
'chunks_exact', which panics on length 0. Catch that case
and bail out, since that makes no sense here anyway.

This could prevent a panic, in case a library sends wrong data.

f9aa980c7d tape: changer: correctly consume data in decode_element_status_page
instead of 'blindly' trusting the changer to deliver the fields written
in the specification, trust the length data it returns in the header.

we slice the descriptor data into equal sized chunks of the correct
size, then we do not have care bout the len and empty checks anymore

this also makes the code to read the rest of the page obsolete,
since the next descriptor is on the correct offset anyway

6c053ffc89 tape: changer: sg_pt: make extra scsi request for dvcid
some libraries cannot handle a request with volume tags and DVCID set at
the same time.

So we make 2 separate requests and merge them, since we want to keep
the vendor/model/serial data.

to not overcomplicate the code, add another special type to ElementType

0ed40b19c7 tape: changer: sg_pt: query element types separately
Some changers do not like the DVCID bit when querying non-drives,
this includes when querying 'all' elements.

To circumvent this, we query each type by itself (like mtx does it),
and only add the DVCID bit for drives (Data Transfer Elements).

Reported by a user in the forum:
https://forum.proxmox.com/threads/ibm-3584-ts3500-support.92291/

and limit to 1000 elements per request.
(Because some changers limit that request with the options we set)

instead of checking if the data len was equal to the allocation_len
for getting more data, we count the returned elements and compare
that with the number we requested

71e83e1b1f tape/changer/sg_pt_changer: read whole descriptor size for each entry
Some changer seem to append more data than we expect, but correctly
annotates that size in the subheader.

For each descriptor entry, read as much as the size given in the
subheader (or until the end of the reader), else our position in
the reader is wrong for the next entry, and we will parse
incorrect data.

78593b5b5c tape/drive: improve error and email handling for requesting a tape load
Try once first to load the correct tape before sending an email to
insert the correct one. This way, the admin does not get a mail
if the correct tape is already inserted.

Also include the error we got that prompted the email to insert the
tape. This means that if the admin gets prompted to insert e.g.
"FOO" but inserts "BAR", he'll get an email that the wrong
tape is inserted.
