4df2e33568 archiver: properly create node for vss backups
Previously, NodeFromFileInfo used the original file path to create the
node, which also meant that extended metadata was read from there
instead of within the vss snapshot.

This change is a temporary solution for restic 0.17.2 and will be
replaced with a clean fix in restic 0.18.0.

fc1fc00aa4 backup: exclude irregular files from backup
restic cannot backup irregular files as those don't behave like normal
files. Thus skip them with an error.

73c9780321 backup: store but warn if extended metadata for item is incomplete
Files were not included in the backup if the extended metadata for the
file could not be read. This is rather drastic. Instead settle on
returning a warning but still including the file in the backup.

bf054c09d2 backup: Ignore xattr.list permission error for parent directories
On FreeBSD, limited users may not be able to even list xattrs for the
parent directories above the snapshot source paths. As this can cause
the backup to fail, just ignore those errors.

2ba21fe72b archiver: only store deviceID for hardlinks
The deviceID can change e.g. when backing up from filesystem snapshot.
It is only used for hardlink detection. Thus there it is not necessary
to store it for everything else.

6b79834cc8 archiver: improve error message for irregular files
Since Go 1.21, most reparse points are considered as irregular files.
Depending on the underlying driver these can exhibit nearly arbitrary
behavior. When encountering such a file, restic returned an
indecipherable error message: `error: invalid node type ""`.

Add the filepath to the error message and state that the file type is
not supported.

c0f34af9db backup: hide files from status which are read completely but not saved
As the FileSaver is asynchronously waiting for all blobs of a file to be
stored, the number of active files is higher than the number of files
from which restic is reading concurrently. Thus to not confuse users,
only display files in the status from which restic is currently reading.

2b88cd6eab archiver: Restructure SaveTree to work like SaveDir
SaveTree did not use the TreeSaver but rather managed the tree
collection and upload itself. This prevents using the parallelism
offered by the TreeSaver and duplicates all related code. Using the
TreeSaver can provide some speed-ups as all steps within the backup tree
now rely on FutureNodes. This can be especially relevant for backups
with large amounts of explicitly specified files.

The main difference between SaveTree and SaveDir is, that only the
former can save tree blobs in which nodes have a different name than the
actual file on disk. This is the result of resolving name conflicts
between multiple files with the same name. The filename that must be
used within the snapshot is now passed directly to
restic.NodeFromFileInfo. This ensures that a FutureNode already contains
the correct filename.

4a10ebed15 archiver: reduce memory usage for large files
FutureBlob now uses a Take() method as a more memory-efficient way to
retrieve the futures result. In addition, futures are now collected
while saving the file. As only a limited number of blobs can be queued
for uploading, for a large file nearly all FutureBlobs already have
their result ready, such that the FutureBlob object just consumes
memory.

c206a101a3 archiver: unify FutureTree/File into futureNode
There is no real difference between the FutureTree and FutureFile
structs. However, differentiating both increases the size of the
FutureNode struct.

The FutureNode struct is now only 16 bytes large on 64bit platforms.
That way is has a very low overhead if the corresponding file/directory
was not processed yet.

There is a special case for nodes that were reused from the parent
snapshot, as a go channel seems to have 96 bytes overhead which would
result in a memory usage regression.

bba1e81719 archiver: Limit blob saver count to GOMAXPROCS
Now with the asynchronous uploaders there's no more benefit from using
more blob savers than we have CPUs. Thus use just one blob saver for
each CPU we are allowed to use.

120ccc8754 repository: Rework blob saving to use an async pack uploader
Previously, SaveAndEncrypt would assemble blobs into packs and either
return immediately if the pack is not yet full or upload the pack file
otherwise. The upload will block the current goroutine until it
finishes.

Now, the upload is done using separate goroutines. This requires changes
to the error handling. As uploads are no longer tied to a SaveAndEncrypt
call, failed uploads are signaled using an errgroup.

To count the uploaded amount of data, the pack header overhead is no
longer returned by `packer.Finalize` but rather by
`packer.HeaderOverhead`. This helper method is necessary to continue
returning the pack header overhead directly to the responsible call to
`repository.SaveBlob`. Without the method this would not be possible,
as packs are finalized asynchronously.
