BackupOSErrora�
Wrapper for OSError raised while accessing backup files.
Borg does different kinds of IO, and IO failures have different consequences.
This wrapper represents failures of input file or extraction IO.
These are non-critical and are only reported (exit code = 1, warning).
Any unwrapped IO error is critical and aborts execution (for example repository IO failure).

this checks for some race conditions between the first filename-based stat()
we did before dispatching to the (hopefully correct) file type backup handler
and the (hopefully) fd-based fstat() we did in the handler.
if there is a problematic difference (e.g. file type changed), we rather
skip the file than being tricked into a security problem.
such races should only happen if:
- we are backing up a live filesystem (no snapshot, not inactive)
- if files change due to normal fs activity at an unfortunate time
- if somebody is doing an attack against us

Return iterator of items.
*ids* is a chunk ID list of an item stream. *filter* is a callable
to decide whether an item will be yielded. *preload* preloads the data chunks of every yielded item.
Warning: if *preload* is True then all data chunks of every yielded item have to be retrieved,
otherwise preloaded chunks will accumulate in RemoteRepository and create a memory leak.
