[PATCH v7 00/21] error: prepare for auto propagated local_err

[Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>]

Hi all!

This is the first part of the bit series, which contains mostly simple
cleanups.

v6 was sent in separate (I'm sorry for inconvenience)

v7: by Markus review (and with his prepared fixups, thanks a lot!):
  - don't rename Error** paramters
  - switch to Error *const * where appropriate
  last patch is new and replaces
   "nbd: well form nbd_iter_channel_error errp handler"

  hw/core/loader-fit: fix freeing errp in fit_load_fdt
