2dbb18128c repository: Allow skipping verification for tests
Some tests have to explicitly create pack files with blobs that don't
match their ID. For those blobs the builtin verification of the
repository must be disabled.

c01a0c6da7 backup: verify blobs before upload
This only covers the blobs themselves, the pack header is not verified
so far. Unpacked files are also not covered by the integrity check.

f1f34eb3e5 lock: checkForOtherLocks processes each lock at most once
If a lock could not be loaded, then restic would check all lock files
again. These repeated checks are not useful as the status of a lock file
cannot change unless its ID changes too. Thus, skip already check lock
files on retries.

2c310a526e repository: Replace StreamPack function with LoadBlobsFromPack method
LoadBlobsFromPack is now part of the repository struct. This ensures
that users of that method don't have to deal will internals of the
repository implementation.

The filerestorer tests now also contain far fewer pack file
implementation details.

22d0c3f8dc check: Use PackBlobIterator instead of StreamPack
To only stream the content of a pack file once, check used StreamPack
with a custom pack load function. This combination was always brittle
and complicates using StreamPack everywhere else. Now that StreamPack
internally uses PackBlobIterator use that primitive instead, which is a
much better fit for what the check command requires.

b1a8fd1d03 rest: fix and cleanup closing of http response body
If client.Do returns an error, then there's no body that has to be
closed. For requests for which we are not interested in the response
body, immediately drain and close the body to make sure it isn't
forgotten later on.

This change in particular adds the missing `Close()` call for the
`List()` command.

0b39940fdb walker: Remove ignoreTrees functionality
It was only used in two places:
- stats: apparently as a minor performance optimization, which is
  unlikely to be important
- find: filtered directories would be ignored. However, this
  optimization missed that it is possible that two directories have the
  exact same content. Such directories would be incorrectly ignored too.
  Example:
```
mkdir test test/a test/b
restic backup test
restic find latest test/b
-> incorrectly does not return anything
```

Thus, remove the functionality as it's apparently too complex to use
correctly.

2e8de9edfd rclone: Workaround for incorrect "not found" errors while listing files
rclone returns a "not found" error if an internal error occurs while
listing a folder. Ignoring this error lets restic erroneously think that
there are no files, which can cause `prune` to wipe the whole
repository.

fe5c337ca2 repository: StreamPack delivers blobs at most once
If an error occurred while streaming a pack file, this could result in
passing some of the blobs multiple times to the callback function. This
significantly complicates using StreamPack correctly and is unnecessary.
Retries do not change the content of a blob and thus only deliver the
same result over and over again.

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.

4a33370072 backend: Fix unreliable TestListCancel/Timeout test
The test uses `WithTimeout` to create a context that cancels the List
operation after a given delay. Several backends internally use a derived
child context created using WithCancel.

The cancellation of a context first closes the done channel of the
context (here: the `WithTimeout` context) and _afterwards_ propagates
the cancellation to child contexts (here: the `WithCancel` context).
Therefor if the List implementation uses a child context, then it may
take a moment until that context is also cancelled. Thus give the
context cancellation a moment to propagate.

Add support for extended attributes on symlinks
Linux allows the use of non-`user.` extended attributes on symlinks. One
of the main users of this functionality is SELinux's `security.selinux`
xattr for storing a path's label. By storing symlink xattrs, restic is
now suitable for backing up the root filesystem on Linux distributions
that use SELinux.

This commit adds support for symlink xattrs when backing up data,
restoring data, and mounting snapshots via a fuse mount. All calls to
the xattr library have been updated to the use `L` variants of the
various functions, which always operate on the path given, without
following symlinks.

Fixes: #4375

0372c7ef04 Improve the ETA displayed during backup
The ETA restic displays was based on a rate computed across the entire
backup operation. Often restic can progress at uneven rates. In the worst
case, restic progresses over most of the backup at a very high rate and
then finds new data to back up. The displayed ETA is then unrealistic and
never adapts.

Restic now estimates the transfer rate based on a sliding window, with the
goal of adapting to observed changes in rate. To avoid wild changes in the
estimate, several heuristics are used to keep the sliding window wide
enough to be relatively stable.

f903db492c backend: let ParseConfig return a Config pointer
In order to change the backend initialization in `global.go` to be able
to generically call cfg.ApplyEnvironment() for supported backends, the
`interface{}` returned by `ParseConfig` must contain a pointer to the
configuration.

An alternative would be to use reflection to convert the type from
`interface{}(Config)` to `interface{}(*Config)` (from value to pointer
type). However, this would just complicate the type mess further.

fc05e35a08 index: let indexmap.Each iterate in allocation order
Iterating through the indexmap according to the bucket order has the
problem that all indexEntries are accessed in random order which is
rather cache inefficient.

As we already keep a list of all allocated blocks, just iterate through
it. This allows iterating through a batch of indexEntries without random
memory accesses. In addition, the packID will likely remain similar
across multiple blobs as all blobs of a pack file are added as a single
batch.

fed33295c3 index: store indexEntries in hashed array tree
This data structure reduces the wasted memory to O(sqrt(n)). The
top-layer of the hashed array tree (HAT) also has a size of O(sqrt(n)),
which makes it cache efficient. The top-layer should be small enough to
easily fit into the CPU cache and thus only adds little overhead
compared to directly accessing an index entry via a pointer.

The indexEntry objects are now allocated in a separate array. References

these do not contain pointers and are part of a single large allocation.

This function casts its argument to int32 before passing it to the

This also gets rid of the last import of "unsafe" in the Unix build.
I changed syscall to x/sys/unix while I was at it, to remove one more
import line. The constants and types there are aliases for their syscall

c0627dc80d check: Fix flaky TestCheckerModifiedData
The test had a 4% chance of not modified the data read from the
repository, in which case the test would fail. Change the data
manipulation to just modified each read operation.

1bd1f3008d walker: extend TreeRewriter to support snapshot repairing
This adds support for caching already rewritten trees, handling of load
errors and disabling the check that the serialization doesn't lead to
data loss.

38dac78180 walker: restructure FilterTree into TreeRewriter
The more generic RewriteNode callback replaces the SelectByName and
PrintExclude functions. The main part of this change is a preparation to
allow using the TreeRewriter for the `repair snapshots` command.

1a9705fc95 walker: Simplify change detection in FilterTree
Now the rewritten tree is always serialized which makes sure that we
don't accidentally miss any relevant changes.

306a29980a Print stacktrace in SIGINT handler if RESTIC_DEBUG_STACKTRACE_SIGINT set
The builtin mechanism to capture a stacktrace in Go is to send a SIGQUIT
to the running process. However, this mechanism is not avaiable on
Windows. Thus, tweak the SIGINT handler to dump a stacktrace if the
environment variable `RESTIC_DEBUG_STACKTRACE_SIGINT` is set.
