- use lockd_lv lock probes for pvmove holder availability in shared VGs

- add cluster lock lifecycle for pvmove LV in shared VGs, and support
  for pvmove in a shared VG

  pvmove; handle active pvmove during vgchange -an with force flags

  deactivation cascade during active pvmove
- support inactive LVs in pvmove with metadata-only mirror insertion;
  kill orphaned polling process on pvmove --abort

Refreshed 002-const-stdio.patch and 003-no-mallinfo.patch against the
new upstream source (make package/lvm2/refresh; hunk offsets only, no
content change) and gave both a proper git-am header block (From/Date/
Subject/Signed-off-by), crediting their original authorship (Daniel
Golle, 2015) with an accurate subject/body; they previously had none,
which the CI formality bot flagged. The header block was drafted via
git format-patch against a scratch commit of the pristine source, then
the whole patch re-refreshed through quilt so the diff body matches
what make package/lvm2/refresh actually produces byte for byte -
format-patch output alone does not survive OpenWrt's own refresh
(diff --git/index lines and full @@ context get stripped, the
trailing signature dropped), which is what the CI patch-format check
was rejecting before this.
