函数名称：sure stacks with components like* :ns:A//&B* have :ns: applied to both 'A' and 'B' by making the lookup relative* to the base if the lookup specifies an ns, else making the stacked lookup* relative to the last embedded ns in the string.

函数原型：static struct aa_profile *fqlookupn_profile(struct aa_label *base, struct aa_label *currentbase, const char *str, size_t n)

返回类型：struct aa_profile

参数：

1837  first等于skipn_spaces - Removes leading whitespace from @str.*@str: The string to be stripped.* Returns a pointer to the first non-whitespace character in @str.* if all whitespace will return NULL
1839  如果first且first恒等于':'则返回:aa_fqlookupn_profile(base, str, n)
