restic: Use stable sorting in snapshot policy 
sort.Sort is not guaranteed to be stable. Go 1.19 has changed the
sorting algorithm which resulted in changes of the sort order. When
comparing snapshots with identical timestamp but different paths and
tags lists, there is not meaningful order among them. So just keep their
order stable.

Michael Eischer caa17988a3 fuse: Redesign snapshot dirstruct 
Cleanly separate the directory presentation and the snapshot directory
structure. SnapshotsDir now translates the dirStruct into a format
usable by the fuse library and contains only minimal special case rules.
All decisions have moved into SnapshotsDirStructure which now creates a
fully preassembled tree data structure.

Michael Eischer 7266f07c87 repository: StreamPack in parts if there are too large gaps 
For large pack sizes we might be only interested in the first and last
blob of a pack file. Thus stream a pack file in multiple parts if the
gaps between requested blobs grow too large.

greatroar ad6ac680af internal/restic: Handle EINVAL for xattr on Solaris 
Also make the errors a bit less verbose by not prepending the operation,
since pkg/xattr already does that. Old errors looked like

    Listxattr: xattr.list /myfiles/.zfs/snapshot: invalid argument

Michael Eischer 623770eebb repository: try to recover from invalid blob while repacking 
If a blob that should be kept is invalid, Repack will now try to request
the blob using LoadBlob. Only return an error if that fails.

Michael Eischer d0590b7841 prune: Add internal integrity check 
After repacking every blob that should be kept must have been repacked.
We have seen a few cases in which a single blob went missing, which
could have been caused by a bitflip somewhere. This sanity check might
help catch some of these cases.

greatroar 2bdc40e612 Speed up restic init over slow SFTP links 
pkg/sftp.Client.MkdirAll(d) does a Stat to determine if d exists and is
a directory, then a recursive call to create the parent, so the calls
for data/?? each take three round trips. Doing a Mkdir first should
eliminate two round trips for 255/256 data directories as well as all
but one of the top-level directories.

Also, we can do all of the calls concurrently. This may reintroduce some
of the Stat calls when multiple goroutines try to create the same
parent, but at the default number of connections, that should not be
much of a problem.
