Bug description:  Missing algorithm type in openssl_verify().

Description:
------------
Can't change algorythm type in  openssl_verify(). So, if data signs by
MD5, openssl_verify() always returns FALSE.

It is caused by openssl_verify() always using the SHA1 algorythm, so I
think it can be improved by adding the 4th parameter (algorythm to use) to
this function, for example, like this: openssl_verify($data, $signature,
$pubkeyid, [, int signature_alg]);

Reproduce code:
---------------
openssl_sign($data, $signature, $priv_key_id, OPENSSL_ALGO_MD5);
$ok = openssl_verify($data, $signature, $pub_key_id);
if ($ok == 1) {
   echo "good";
} elseif ($ok == 0) {
   echo "bad";
}

This returns always "bad".

Expected result:
----------------
"ok", but it's impossible :(
