dd9acc98eb add ident to zedlet-list creation patch
the last series of cherry-picks from salsa.d.o includes one patch for the
zfs-source, but the patch file does not contain ident-information.
This prevents it from being applied by import-patchqueue.

Fixed by adding ident based on the original patches commit message and
importing and exporting the patchqueue.

4d56f4c5b5 Preserve /etc/zfs/zed.d configuration on upgrade
Of the zedlet scripts shipped by upstream, a subset are enabled by
default, by creating symlinks in /etc/zfs/zed.d.  These symlinks are
shipped in the zfs-zed package.  dpkg, however, does not support
conffile handling of symlinks, and therefore any changes (removals) to
the symlinks are not preserved on package upgrade.

To address this policy violation, we:

 1. During package build, create a list of enabled-by-default zedlets,
    instead of creating symlinks.
 2. On package removal, identify all enabled-by-default zedlets whose
    symlinks do not exist (i.e., were removed by the user). This is done
    by creating "whiteout" links to /dev/null in their place).
 3. On package installation, create links to enabled-by-default zedlets
    UNLESS there is already a file there (i.e., abort if there is a
    whiteout link).
 4. We also clean up broken symlinks to removed zedlets at package
    postinst.
