archive_acl.rs数据结构定义未使用Rust特性，同时枚举类型/宏定义变成魔鬼数字导致无法阅读

### 原生C语言定义
```
static const struct {
	const int perm;
	const char c;
	const wchar_t wc;
} nfsv4_acl_perm_map[] = {
	{ ARCHIVE_ENTRY_ACL_READ_DATA | ARCHIVE_ENTRY_ACL_LIST_DIRECTORY, 'r',
	    L'r' },
	{ ARCHIVE_ENTRY_ACL_WRITE_DATA | ARCHIVE_ENTRY_ACL_ADD_FILE, 'w',
	    L'w' },
	{ ARCHIVE_ENTRY_ACL_EXECUTE, 'x', L'x' },
	{ ARCHIVE_ENTRY_ACL_APPEND_DATA | ARCHIVE_ENTRY_ACL_ADD_SUBDIRECTORY,
	    'p', L'p' },
	{ ARCHIVE_ENTRY_ACL_DELETE, 'd', L'd' },
	{ ARCHIVE_ENTRY_ACL_DELETE_CHILD, 'D', L'D' },
	{ ARCHIVE_ENTRY_ACL_READ_ATTRIBUTES, 'a', L'a' },
	{ ARCHIVE_ENTRY_ACL_WRITE_ATTRIBUTES, 'A', L'A' },
	{ ARCHIVE_ENTRY_ACL_READ_NAMED_ATTRS, 'R', L'R' },
	{ ARCHIVE_ENTRY_ACL_WRITE_NAMED_ATTRS, 'W', L'W' },
	{ ARCHIVE_ENTRY_ACL_READ_ACL, 'c', L'c' },
	{ ARCHIVE_ENTRY_ACL_WRITE_ACL, 'C', L'C' },
	{ ARCHIVE_ENTRY_ACL_WRITE_OWNER, 'o', L'o' },
	{ ARCHIVE_ENTRY_ACL_SYNCHRONIZE, 's', L's' }
};
```

### RUST重构后的定义
```
static mut nfsv4_acl_perm_map: [nfsv4_acl_perm_map_struct; 14] = [
    {
        let mut init = nfsv4_acl_perm_map_struct {
