This helpers are used to construct the extended attributes values from
the ACLs stored in the pxar archive.

They are not only needed by the pxar::sequential_decoder but also for the fuse
xattr impl, so it makes more sense to have them there.

The goodbye table of directory entries is cached in a LRU cache to speed up
subsequent accesses.
This is especially important for directories with many entries, as then the
readdirplus callback is called repeatedly because of the limited reply buffer
size.
`DirectoryEntry`s are cached for subsequent access in their own LRU cache,
independent of the goodbye tables.
In order to avoid borrow conflicts, the `Context` provides a fn as_mut_refs
as well as a fn run_with_context_refs.

By passing `&DirectoryEntry` to stat, the function interface is simplified.

This will return a mutable reference just like get_mut, but on a cache miss
it will get and insert the missing value via the fetch method provided via the
Cacher trait.

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.
