Revision 345

Improvements to Net::SSLeay::read to make it easier to use with non-blocking IO:
      contributed by James Marshall:  It modifies
      Net::SSLeay::read() to return the result from SSL_read() as the second
      return value, if Net::SSLeay::read() is called in list context.  Its
      behavior should be unchanged if called in scalar or void context.  This
      result code seems to be required for full support of non-blocking I/O,
      since users need to handle SSL_ERR_WANT_READ, SSL_ERROR_WANT_WRITE, etc.
