Let's define two helpers strdupa_safe() + strndupa_safe() which do the same as their non-safe counterparts, except that they abort if called with allocations larger than ALLOCA_MAX. This should ensure that all our alloca() based allocations are subject to this limit. afaics glibc offers three alloca() based APIs: alloca() itself, strndupa() + strdupa(). With this we have now replacements for all of them, that take the limit into account.
