Add the following ACL editing functions:
acl_add_perm, acl_clear_perms, acl_copy_entry, acl_create_entry,
acl_delete_perm, acl_get_permset, acl_get_qualifier, acl_get_tag_type,
acl_set_permset, acl_set_qualifier, acl_set_tag_type
This brings us within 4 functions of a full ACL editing library.

Add NFSv4 ACL support to libc.
This adds the following functions to the acl(3) API: acl_add_flag_np,
acl_clear_flags_np, acl_create_entry_np, acl_delete_entry_np,
acl_delete_flag_np, acl_get_extended_np, acl_get_flag_np, acl_get_flagset_np,
acl_set_extended_np, acl_set_flagset_np, acl_to_text_np, acl_is_trivial_np,
acl_strip_np, acl_get_brand_np. Most of them are similar to what Darwin
does. There are no backward-incompatible changes.
