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.
