I am going to need an ifdef anyway, once for < PHP 7 and once for >= PHP
7...

I think it makes perfect sense to have two styles. Keep the current zpp
that we have, and only optimise it with the much less readable versions
for functions (think strlen()) that are called a lot.

Both of them very much suck as API compared to:
if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "ZZZ|lZ", ®ex,
&replace, &subject, &limit, &zcount) == FAILURE) {
As I mentioned before, keep the current zpp working, and add a special
one for the functions where a faster one really matters.
