Hi all,

This patchset adds support for the VAG container and ADPCM variant used
by some Simon & Schuster Interactive games such as 'Real War',
and 'Real War: Rogue States'.

It has been tested against VAG files from both games.

Some things to note:
* SSI's VAG has no relation to the existing PS2 VAG.
  I've named it 'kvag' (after its tag), but am open to suggestions if this
  is inappropriate (ssi_vag?).
* The ROUNDED_DIV() call causes a (harmless) warning when called with
  unsigned arguments. I'm not sure of the policy for situations like this.

Zane
