Description:
The function 'SSL_get_cipher_list' in yaSSL returns all avalible ciphers in one call to
the function. This is not compatibel with the openSSL implementation that only one cipher
is returned for each call, and eventually NULL when there is no cipher with the given
pritority.

How to repeat:
Function is used in 'show_ssl_get_cipher_list'.

static int show_ssl_get_cipher_list(THD *thd, SHOW_VAR *var, char *buff)
{
  var->type= SHOW_CHAR;
  var->value= buff;
  if (thd->net.vio->ssl_arg)
  {
    int i;
    const char *p;
    char *end= buff + SHOW_VAR_FUNC_BUFF_SIZE;
    for (i=0; (p= SSL_get_cipher_list((SSL*) thd->net.vio->ssl_arg,i)) &&
               buff < end; i++)
    {
      buff= strnmov(buff, p, end-buff-1);
      *buff++= ':';
    }
    if (i)
      buff--;
  }
  *buff=0;
  return 0;
}

Suggested fix:
Make only one cipher be returned for each priotity level.

Commited to upstream yaSSL to be inlcuded in MySQL soon

Updated our yaSSL dsitribbution from upstreame im 5.0.21 and thus fixed thie problem.

Noted in 5.0.21 changelog.
