last_successful_backup: Returns the time of the last successful backup
group_path: Returns the absolute path for a backup_group
snapshot_path: Returns the absolute path for a backup_dir
It's a bit dangerous as it points to all the saved backups, so they
would be seemingly lost after updating the path.
Follow our logic from other products, e.g. in PVE we do not allow to
update the backing path/location of a storage either for similar
reasons.

Implements a cache with least recently used cache replacement policy.
Internally the state is tracked by a HashMap (for fast access) and a doubly
linked list (for the access order).

The -sys, -tools and -api crate have now been merged into
the proxmx crate directly. Only macro crates are separate
(but still reexported by the proxmox crate in their
designated locations).
When we need to depend on "parts" of the crate later on
we'll just have to use features.
The reason is mostly that these modules had
inter-dependencies which really make them not independent
enough to be their own crates.

This allows to read the target path of a symbolic link in the
Decoder::read_directory_entry() function and stores it in the DirectoryEntry.
By this the Decoder::read_link() function becomes obsolete and is therefore
removed.

By ambiguously using the Decoder::read_directory_entry() the code is simplified
and reading of the DirectoryEntry is concentrated into Context::run_in_context().

Previously it was disciminated based on the entry mode.
For directories, the inode was the offset of the corresponding
goodbye tail mark while for all others it was the offset of the filename.
By simply using the start offset as calculated from the corresponding
goodbye table entry (which yields the archive offset of the filename),
the code is simplified and the more ambiguous read_directory_entry()
function can be used.
The disatvantage of this approach is the need to keep track of the
start and end offsets for each entry, as the end offset is needed in
order to access the goodbye table of directory entries.
The root node still has to be treated special, as it's inode is 1 as per fuse
definition and it has no filename as per the pxar file format definition.

Use Decoder::read_directory_entry() instead of Decoder::attributes() as this
already returns the needed DirectoryEntry.

By not implementing readdir but only readdirplus, the FUSE_CAP_READDIRPLUS flag
is set while the FUSE_CAP_READDIRPLUS_AUTO flag is not set.
Thereby the kernel will issue only readdirplus calls.
Documentation at:
https://libfuse.github.io/doxygen/fuse-3_88_80_2include_2fuse__common_8h.html#a9b90333ad08d0e1c2ed0134d9305ee87
As the expensive part for accessing and reading the attributes is seeking and
decoding each directory entry, it is usefull to force readdirplus calls.
By this a struct `EntryParam` is returned for each entry, therebye avoiding a
subsequent lookup call.
