Correcting my statement in the previous commit: 

There is defined correspondence between ACL and st_mode in Linux man 5 acl.
It is complicated and libisofs will have to ensure integrity of ACL
manipulations and st_mode manipulations. (It will not check integrity when
loading ACLs and st_mode from filesystems.)

/* Linux man 5 acl says:
The permissions defined by ACLs are a superset of the permissions speci-
fied by the file permission bits. The permissions defined for the file
owner correspond to the permissions of the ACL_USER_OBJ entry. The per-
missions defined for the file group correspond to the permissions of the
ACL_GROUP_OBJ entry, if the ACL has no ACL_MASK entry. If the ACL has an
ACL_MASK entry, then the permissions defined for the file group corre-
spond to the permissions of the ACL_MASK entry. The permissions defined
for the other class correspond to the permissions of the ACL_OTHER_OBJ
entry.
Modification of the file permission bits results in the modification of
the permissions in the associated ACL entries. Modification of the per-
missions in the ACL entries results in the modification of the file per-
mission bits.
