Because config cannot employ the journaling mechanism, this patchset
adds a new API, atomic_create_and_write() and let the config subsystem
use it for safe update of its data.

v2:
 - move def_fmode and def_dmode to libsheepdog.a
 - don't panic() even if temporal files reamin
 - remove unnecessary access(2) in check_tmp_config()

Hitoshi Mitake (4):
  journal: remove journaling support for config
  util: move def_fmode and def_dmode to libsheepdog.a
  util: add a new API atomic_create_and_write()
  sheep: let config use atomic_create_and_write()
