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).

30316192b3 tape: improve locking (lock media-sets)
- new helper: lock_media_set()

- MediaPool: lock media set

- Expose Inventory::new() to avoid double loading

- do not lock pool on restore (only lock media-set)

- change pool lock name to ".pool-{name}"

237314ad0d tape: improve catalog consistency checks
Try to check if we read the correct catalog by verifying uuid, media_set_uuid
and seq_nr.

Note: this changes the catalog format again.

Deduplication is now per datastore (not per media set).
