bee3231ed4 lock: try refreshing of stale locks 
A stale lock may be refreshed if it continues to exist until after a
replacement lock has been created. This ensures that a repository was
not unlocked in the meantime.

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

b7f03d01b8 Add helper function for Duration parsing

Function parseDuration(...) was moved to testing.go  and renamed to
ParseDurationOrPanic(...).

a7786c67f1 cmd, restic: Refactor and fix snapshot filtering 
This turns snapshotFilterOptions from cmd into a restic.SnapshotFilter
type and makes restic.FindFilteredSnapshot and FindFilteredSnapshots
methods on that type. This fixes #4211 by ensuring that hosts and paths
are named struct fields instead of unnamed function arguments in long
lists of such.

Timestamp limits are also included in the new type. To avoid too much
pointer handling, the convention is that time zero means no limit.
That's January 1st, year 1, 00:00 UTC, which is so unlikely a date that
we can sacrifice it for simpler code.
