[PATCH v2 0/6] xv: Fix auto key color fill with reput image & code clean up

[Pauli]

From: Pauli Nieminen <ext-pauli.nieminen at nokia.com>

This set fixes following problems in previous patches:
* If there is expose but clipboxes don't change driver doesn't know to fill 
  the color key
* Crash in PostValidateTree when pLayerWin is NULL
* Prevent infinite recursion when wrapping PostValidateTree

I still need to cook patches to take advantage of the xf86XVGetPortFillArea in
drivers if these patches look good.

Pauli Nieminen (6):
  xf86/xv: Remove copy paste code.
  xf86/xv: Remove unused GC pointers
  xf86/xv: Remove unused variable from XvPortRecPrivate
  xf86/xv: Fill color key on expose
  xf86/xv: Use PostValidateTree to do reput
  xf86/xv: Only register PostValidateTree hook when there is work to do
