Fix prime generation loop in crypto/bn/bn_prime.pl by making

 Changes between 0.9.7c and 0.9.8  [xx XXX xxxx]

  *) Fix prime generation loop in crypto/bn/bn_prime.pl by making

     sure the loop does correctly stop and breaking ("division by zero")

     modulus operations are not performed. The (pre-generated) prime

     table crypto/bn/bn_prime.h was already correct, but it could not be

     re-generated on some platforms because of the "division by zero"

     situation in the script.

  *) Update support for ECC-based TLS ciphersuites according to

     draft-ietf-tls-ecc-03.txt: the KDF1 key derivation function with

     SHA-1 now is only used for "small" curves (where the

	$p+=2;

	$s=int(sqrt($p));

	for ($i=0; $primes[$i]<=$s; $i++)

	for ($i=0; defined($primes[$i]) && $primes[$i]<=$s; $i++)

		{

		next loop if (($p%$primes[$i]) == 0);
