Subject: Cleanup handling of packed attribute.

- Add a configure test for the attribute, during xine build process.
- Define the attribute as supported when using GCC 2.95 or later
  outside xine build process.
- Use the new XINE_PACKED define instead of the attribute directly.
- Check for SUPPORT_ATTRIBUTE_PACKED rather than doing strange
  subdefines.
