  This is just the patches to implement the infrastructure of the
timer_shutdown_sync() and timer_shutdown(). I'll leave the scripting for the
second stage if this is approved.

Changes since the v5a: https://lore.kernel.org/all/20221106054535.709068702@goodmis.org/

- Broke up the implementation patch into three patches:

  1. The code taken from Thomas and tweaked to compile and added comments,
     as well as changing the name to timer_shutdown_sync():
     https://lore.kernel.org/all/20221106054535.709068702@goodmis.org/

  2. Addition of timer_shutdown() that is like del_timer() but uses the same
     logic as timer_shutdown_sync() to disable the timer after it is called.

  3. Update the documentation to reflect the new APIs.

      timers: Add timer_shutdown_sync() to be called before freeing timers
      timers: Add timer_shutdown() to be called before freeing timers
      timers: Update the documentation to reflect on the new timer_shutdown() API
