  backup-rename: new module
  
  It is like backupfile, except it avoids some race conditions,
  and it does not output to stderr or exit.
  * MODULES.html.sh: Add backup-rename.
  * lib/backup-find.c, lib/backup-internal.h, lib/backup-rename.c:
  * modules/backup-rename: New files.
  * lib/backupfile.c: Turn this into an internals file, which
  contains code common to backupfile and backup_rename.  Do not
  include argmatch.h or xalloc.h: include xalloc-oversized.h.
  Include renameat2.h and fcntl.h.
  (BACKUP_NOMEM): New constant.
  (numbered_backup): New args BASE_OFFSET and *DIRPP.  Do not exit
  on memory exhaustion; just return BACKUP_NOMEM.  Caller changed.
  (backupfile_internal): Rename from find_backup_file_name.
  Support new arg RENAME.
  (backup_args, backup_types, get_version, xget_version):
  Move to lib/backup-find.c.
  * lib/backupfile.h (backup_file_rename): New decl.
  * modules/backupfile (Files): Add lib/backup-internal.h,
  lib/backup-find.c.
  (Depends-on): Add dirfd, fcntl, renameat2.
  (lib_SOURCES): Add backup-find.c.
