I'm testing this patch over ra_svn and ra_dav support. I'll let you know
how it goes.

Yes, I've prepared the list of other redundant functions. I found such
functions in fs.c, err.c, dag.c, id.c and lock.c belonging to FSFS and
BDB. They are as follows:

List of redundant functions in libsvn_fs_fs/fs.c & libsvn_fs_base/fs.c:
check_already_open(), check_already_open()
svn_fs_fs__canonicalize_abspath(), svn_fs_base__canonicalize_abspath()
fs_version(), base_version()

List of redundant functions in libsvn_fs_fs/dag.c &
svn_fs_fs__dag_make_file(), svn_fs_base__dag_make_file()
svn_fs_fs__dag_make_dir(), svn_fs_base__dag_make_dir()
svn_fs_fs__dag_node_kind(), svn_fs_base__dag_node_kind()
svn_fs_fs__dag_get_id(), svn_fs_fs__dag_get_id()
svn_fs_fs__dag_get_created_path(), svn_fs_base__dag_get_created_path()
svn_fs_fs__dag_get_fs(), svn_fs_base__dag_get_fs()
svn_fs_fs__dag_check_mutable, svn_fs_base__dag_check_mutable()

List of redundant functions in libsvn_fs_fs/err.c &
svn_fs_fs__check_fs(), svn_fs_base__check_fs()
svn_fs_fs__err_not_mutable(), svn_fs_base__err_not_mutable()
svn_fs_fs__err_txn_not_mutable(), svn_fs_base__err_txn_not_mutable()
svn_fs_fs__err_not_directory(), svn_fs_base__err_not_directory()
svn_fs_fs__err_not_file(), svn_fs_base__err_not_file()
svn_fs_fs__err_path_already_locked(), svn_fs_base__err_path_already_locked()
svn_fs_fs__err_no_such_lock(), svn_fs_base__err_no_such_lock()
svn_fs_fs__err_lock_expired(), svn_fs_base__err_lock_expired()
svn_fs_fs__err_no_user(), svn_fs_base__err_no_user()

svn_fs_fs__err_path_already_locked(), svn_fs_base__err_path_already_locked()
svn_fs_fs__err_no_such_lock(), svn_fs_base__err_no_such_lock()

List of redundant functions in libsvn_fs_fs/id.c & libsvn_fs_base/id.c:
svn_fs_fs__id_node_id(), svn_fs_base__id_node_id()
svn_fs_fs__id_copy_id(), svn_fs_base__id_copy_id()

List of redundant functions in libsvn_fs_fs/lock.c &
svn_fs_fs__check_path(), base_check_path()
next_entry_name(), next_entry_name()
make_parent_path(), make_parent_path()
parent_path_path(), parent_path_path()
