st/mesa: rework viewport/scissor initialization codegallium-mesa-7.4
This is a hand-pick of some of the new viewport code committed to mesa_7_5_branch. See commit 3f856c6b6b7fa95ef97a8712876de88d7d57932e for reference. This is just the state_tracker part. The core Mesa part came from merging in mesa_7_4_branch.
