This patchset improves the user experience around memory onlining,
specifically the state it is onlined in - movable vs non-movable. It
also adds an option to make the memory non-movable when onlining.

Patches 1-3 perform some preparatory and clean up steps.
Patches 4-6 add a way to determine and display the 'movable' vs
'non-movable' state of memory.
Patches 7-8 attempt to detect a race with memory onlining, and add a
Documentation clarification
Patches 9-10 Add the new --no-movable option to commands that may
online memory.

  libdaxctl: refactor path construction in op_for_one_memblock()
  libdaxctl: refactor memblock_is_online() checks

  libdaxctl: add an API to determine if memory is movable
  libdaxctl: allow memblock_in_dev() to return an error
  daxctl: show a 'movable' attribute in device listings
  daxctl: detect races when onlining memory blocks
  Documentation: clarify memory movablity for reconfigure-device
