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.

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.

add a helper to perform some basic checks on password prompts.
- verification (asks for a 2nd time)
- check length
also use the new helper where password input in tty is taken to reduce
duplicate code.
this helper should be used when creating keys, changing passphrases etc.
note: this helper can be extended later on to provide better checks for
password strength.

readdirplus returns the entries together with their `EntryParam`, so subsequent
lookups for each of the entries are avoided.
In order to reduce code duplication, the code for filling the reply buffer is
moved into a macro.

Limit the total number of entries and therefore the approximate memory
consumption instead of doing this on a per directory basis as it was previously.
This makes more sense as it limits not only the width but also the depth of the
directory tree.
Further, instead of hardcoding this value, allow to pass this information as
additional optional parameter 'entires-max'.
By this, creation of the archive with directories containing a large number of
entries is possible.

If during creation of the archive, files/dirs with lacking read permissions are
encountered, the user is displayed a warning and the archive is created without
including the file/dir.
Previously this resulted in an error and the archive creation failed.
In order to implement this also for the .pxarexclude files, the Error type of
MatchPattern::from_file() and MatchPattern::from_line() was adopted accordingly.

If nodes are excluded by feature flags, they must not appear in the goodbye table.
This is fixed by continuing with the next entry in the for loop.
Further the relative path buffer is now poped in order to correctly display the path.
