1f4c9d2806 cache: correctly ignore files whose filename is no ID
this can for example be the case for temporary files created by the
backend implementation.

ac5bc7c2f9 fs: fix error handling for retried get/set of security descriptor
The retry code path did not filter `ERROR_NOT_SUPPORTED`. Just call the
original function a second time to correctly follow the low privilege
code path.

3e4c1ea196 fs: fix race condition in get/set security descriptor
Calling `Load()` twice for an atomic variable can return different
values each time. This resulted in trying to read the security
descriptor with high privileges, but then not entering the code path to
switch to low privileges when another thread has already done so
concurrently.

8828c76f92 rest: improve handling of HTTP2 goaway
The HTTP client can only retry HTTP2 requests after receiving a GOAWAY
response if it can rewind the body. As we use a custom data type,
explicitly provide an implementation of `GetBody`.

6eece31dc3 lock: introduce short delay between failed locking retries
Failed locking attempts were immediately retried up to three times
without any delay between the retries. If a lock file is not found while
checking for other locks, with the reworked backend retries there is no
delay between those retries. This is a problem if a backend requires a
few seconds to reflect file deletions in the file listings. To work
around this problem, introduce a short exponentially increasing delay
between the retries. The number of retries is now increased to 4. This
results in delays of 5, 10 and 20 seconds between the retries.

8206cd19c8 backend/retry: don't trip circuit breaker if context is canceled
When the context used for a load operation is canceled, then the result
is always an error independent of whether the file could be retrieved
from the backend. Do not false positively trip the circuit breaker in
this case.

The old behavior was problematic when trying to lock a repository. When
`Lock.checkForOtherLocks` listed multiple lock files in parallel and one
of them fails to load, then all other loads were canceled. This
cancelation was remembered by the circuit breaker, such that locking
retries would fail.

61aaddac28 restic: restore timestamps after extended attributes
restoring the xattr containing resource forks on macOS apparently
modifies the file modification timestamps. Thus, restore the timestamp
after xattrs.

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.

88f59fc2d6 json: switch backup and restore errors from string to struct types
This keeps backwards compatibility with the previous empty structs.
And maybe we'd want to put other fields into the inner struct later,
rather than the outer message.

ad2585af67 backup: show actual error strings in --json mode
Previously, an error JSON fragment would look like:
{"message_type": "error", "error": {}}

This is because encoding/json cannot marshal an error interface.
Instead, we now call .Error() to get the string value.

6a97833337 restore: clean up error handling when restoring metadata
- Fix a logic error that instead of reporting the *first*
  metadata-setting error that appears, we were instead reporting the
  *last* error (and only if the lchown call failed!).
- Don't show any errors when setting metadata for files in non-root
  mode (things like timestamps, attributes). Previously, only lchown
  errors were skipped. But other kinds of attribute errors make sense
  to skip as well. The code path happened to work correctly before
  because of the above logic error. But once that was fixed, this
  change needed to happen too.
