[Libguestfs] [PATCH common v2 0/4] Windows BitLocker support.

For links to the original patch series, see: https://bugzilla.redhat.com/show_bug.cgi?id=1808977#c8 The original feedback was that ignoring errors from guestfs_luks_uuid would ignore legitimate errors from non-BitLocker disks, so I have modified this series so that errors are only ignored in the BitLocker case. As noted in the 4th patch there is no actual error in the BitLocker case, cryptsetup luksUUID simply exits without printing anything. Rich.
