80ed863aab repository: remove redundant cleanup code 
The temp files used by the packer manager are either delete after
creation (unix) or marked as delete on close (windows). Thus, no
explicit cleanup is necessary.

9c70794886 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.

6fbfccc2d3 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.

2296fdf668 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.

e24dd5a162 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.

36c4475ad9 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`.

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.

Previously, an error JSON fragment would look like:

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.

5d6ce59a8d restorer: also truncate files if their content is already uptodate 
Files for which no blobs have to be restored, still have to be truncated
to the correct size. Take a file with content "foobar" that should be
replaced by restore with content "foo". The first three bytes are
already uptodate, such that no data has to be written. As file
truncation normally happens when writing data, a special case is
necessary.

This no blobs written special case is unified with the empty file
special case.
