c1a3de4a6e Refactor max-unused calculation, add unlimited option
Add a callback to the PruneOptions struct which calculates the number of
bytes allowed to be unused after prune is done. This way, the logic is
closer to the option parsing code.

Also, add an explicit option `unlimited` for the use case when storage
does not matter but bandwidth and time do. Internally, this sets the
maximum number of unused bytes to MaxUint64.

Rework the documentation slightly so that no more "packs" are
mentioned and it talks about "files" instead.

Make it clear in the documentation that the percentage given to
`--max-unused` is relative to the whole repository size after pruning is
done. If specified, it must be below 100%, otherwise the repository
would contain 100% of unused data, which is pointless.

I had a hard time coming up with the correct formula to calculate the
maximum number of unused bytes based on the number of used bytes. For a
fraction `p` (0 ≤ p < 1), a repo with `u` bytes used, and the number of
unused bytes `x` the following holds:

      x ≤ p * (u+x)
    ⇔ x ≤ p*u + p*x
    ⇔ x - p*x ≤ p*u
    ⇔ x * (1-p) ≤ p*u
    ⇔ x ≤ p/(1-p) * u

5695f9ebd2 vss: Implement VSS support for Windows
The VSS support works for 32 and 64-bit windows, this includes a check that
the restic version matches the OS architecture as required by VSS. The backup
operation will fail the user has not sufficient permissions to use VSS.

Snapshotting volumes also covers mountpoints but skips UNC paths.

e638b46a13 Embed context into ReaderAt
The io.Reader interface does not support contexts, such that it is
necessary to embed the context into the backendReaderAt struct. This has
the problem that a reader might suddenly stop working when it's
contained context is canceled. However, this is now problem here as the
reader instances never escape the calling function.

bcc3bddcf4 filter: only check whether a child path could match when necessary
When checking excludes there is no need to test whether a child path
could also match the pattern, as it is by definition excluded.
Previously childMayMatch was calculated but then discarded. For simple
absolute paths this can account for half the time spent for checking
pattern matches.

c4e2203e45 Check error in archiver before calling Select
The archiver first called the Select function for a path before checking
whether the Lstat on that path actually worked. The RejectFuncs in
exclude.go worked around this by checking whether they received a nil
os.FileInfo. Checking first is more obvious and requires less code.

Don't require self-update --output placeholder file
This removes the requirement on `restic self-update --output` to point
to a path of an existing file, to overwrite. In case the specified
path does exist we still want to verify that it's a regular file,
rather than a directory or a device, which gets overwritten.

We also want to verify that a path to a new file exists within an
existing directory. The alternative being running into that issue
after the actual download, etc has completed.

While at it I also replace `errors.Errorf` with the more appropriately
verbose `errors.Fatalf`.

f5c448aa65 diff: Optimize diff calculation for shared subtrees
When the diff calculation compares two trees with identical id then no
differences between them can ever show up. Optimize for that case by
simply traversing the tree only once to collect all referenced blobs for
a proper calculation of added and removed blobs.

Just skipping the common subtrees is not possible as this would skew the
results if the added or removed blobs are shared with one of the
subtrees.

There was an issue that prevented the dump command from working
correctly when either:

* `/` contained multiple nodes (e.g. `restic backup /`)
* dumping a file in the first sublevel was attempted (e.g. `/foo`)

d5f86effa1 ls: Explicitly enforce that the user specifies a snapshot ID
The help messages suggested that the `ls` command work without
explicitly passing a snapshot ID. However, this was never the case:
without a snapshot ID the command just failed with the error
`Ignoring "", it is not a snapshot id`.

Fixes #2299

ec9a53b7e8 copy: Mark and skip previously copied snapshots
Use the `Original` field of the copied snapshot to store a persistent
snapshot ID. This can either be the ID of the source snapshot if
`Original` was not yet set or the previous value stored in the
`Original` field. In order to still copy snapshots modified using the
tags command the source snapshot is compared to all snapshots in the
destination repository which have the same persistent ID. Snapshots are
only considered equal if all fields except `Original` and `Parent`
match. That way modified snapshots are still copied while avoiding
duplicate copies at the same time.
