    xtables: use strspn() to check if string needs to be quoted
    
    Problem: the call xtables_save_string("'") prints just a single quote,
    not enclosed in double quoted and not escaped.
    
    Steps to reproduce:
    
     $ iptables -A foo -m comment --comment "'" -j ACCEPT
     $ iptables-multi save|grep foo
     -A foo -m comment --comment ' -j ACCEPT
    
    The cause was the use of strcspn() to locate the first character which
    justified quoting the string in double quotes.  That however was
    wrong, because the way strcspn() was called, it returned a pointer to
    the first character that was not to be escaped, which did the right
    thing most of the time, but not for strings consisting only of quote
    characters.  This patch changes strcspn() to strspn().
