1d0d5d87bc fs: fix error in fillGenericAttributes for vss volumes
Extended attributes and security descriptors apparently cannot be
retrieved from a vss volume. Fix the volume check to correctly detect
vss volumes and just completely disable extended attributes for volumes.

03aad742d3 fs: add correct vss support to fixpath
Paths that only contain the volume shadow copy snapshot name require
special treatment. These paths must end with a slash for regular file
operations to work.

8f20d5dcd5 fs: Refactor UtimesNano replacements
Previously, nodeRestoreTimestamps would do something like

	if node.Type == restic.NodeTypeSymlink {
	    return nodeRestoreSymlinkTimestamps(...)
	}
	return syscall.UtimesNano(...)

where nodeRestoreSymlinkTimestamps was either a no-op or a
reimplementation of syscall.UtimesNano that handles symlinks, with some
repeated converting between timestamp types. The Linux implementation
was a bit clumsy, requiring three syscalls to set the timestamps.

In this new setup, there is a function utimesNano that has three
implementations:

* on Linux, it's a modified syscall.UtimesNano that uses
  AT_SYMLINK_NOFOLLOW and AT_FDCWD so it can handle any type in a single
  call;
* on other Unix platforms, it just calls the syscall function after
  skipping symlinks;
* on Windows, it's the modified UtimesNano that was previously called
  nodeRestoreSymlinkTimestamps, except with different arguments.

f967a33ccc fs: Use AT_FDCWD in Linux nodeRestoreSymlinkTimestamps
There's no need to open the containing directory. This is exactly what
syscall.UtimesNano does, except for the AT_SYMLINK_NOFOLLOW flag.

60960d2405 fs/vss: properly create node from vss path
Previously, NodeFromFileInfo used the original file path to create the
node, which also meant that extended metadata was read from there
instead of within the vss snapshot.

2b609d3e77 errors, fs: Replace CombineErrors with stdlib Join
This does not produce exactly the same messages, as it inserts newlines
instead of "; ". But given how long our error messages can be, that
might be a good thing.

f9dbcd2531 backup: convert reject funcs to use FS interface
Depending on parameters the paths in a snapshot do not directly
correspond to real paths on the filesystem. Therefore, reject funcs must

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.
