To support incremental backups (where not all chunks are sent to the
server), a new parameter "reuse-csum" is introduced on the
"create_fixed_index" API call. When set and equal to last backups'
checksum, the backup writer clones the data from the last index of this
archive file, and only updates chunks it actually receives.
In incremental mode some checks usually done on closing an index cannot
be made, since they would be inaccurate.

we want to get a string representation of the DirEntryAttribute
like 'f' for file, etc. and since we have such a mapping already
in the CatalogEntryType, use that

mostly copied from BufferedDynamicReadAt from proxmox-backup-client
but the reader is wrapped in an Arc in addition to the Mutex
we will use this for local access to a pxar behind a didx file

implements AsyncRead as well as Stream for an IndexFile and a store
that implements AsyncReadChunk
we can use this to asyncread or stream the content of a FixedIndex or
DynamicIndex

we want to save if a file of a backup is encrypted, so that we can
* show that info on the gui
* can later decide if we need to decrypt the backup

copy_nonoverlapping is basically a memcpy which can also be done
via copy_from_slice which is not unsafe
(copy_from_slice uses copy_nonoverlapping internally)

the last chunk does not have to be as big as the chunk_size,
just use the already available 'chunk_end' function which does the
correct thing
this fixes restoration of images whose sizes are not a multiple of
'chunk_size' as well

This is basically a rewrite of the current logic for navigating the catalog,
but in addition allows to follow symlinks.
Following symlinks introduces the issue that generation of canonical paths
(needed in the actual pxar archive) is more complex, as symlinks have to be
resolved and loops avoided.

'clear-selected' allows to clear all the match patterns from the list of
patterns for a subsequent restore.
