a7188b3a75 tape: fix FORMAT for LTO-4 drives 
FORMAT requires LTO-5 or newer, so we do a rewind/erase if FORMAT fails.

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.

c6f55139f8 tape: impl. MediaCatalog::parse_catalog_header 
This is just an optimization, avoiding to read the catalog into memory.

We also expose create_temporary_database_file() now (will be
used for catalog restore).
