On the fsfs-format7 branch:  update callers of the deprecated
svn_io_file_create to svn_io_file_create2.  Use the default (0)
length value everywhere, except for those few places where the
actual length is obvious and unlikely to change

* subversion/libsvn_client/patch.c
  (install_patched_prop_targets): call with defaults

* subversion/libsvn_fs_fs/fs.c
  (fs_open_for_recovery): ditto

* subversion/libsvn_fs_fs/fs_fs.c
  (write_config,
   create_file_ignore_eexist,
   write_revision_zero): same here
  (upgrade_body): call with specific length
  (svn_fs_fs__create): do both

* subversion/libsvn_fs_fs/hotcopy.c
  (hotcopy_create_empty_dest): same here

* subversion/libsvn_fs_fs/transaction.c
  (get_lock_on_filesystem): call with defaults
  (svn_fs_fs__create_txn): call with specific length

* subversion/libsvn_repos/repos.c
  (create_db_logs_lock,
   create_db_lock,
   create_conf): call with defaults

* subversion/libsvn_wc/adm_files.c
  (init_adm): call with defaults
