Do not use XAAGetCopyROP outside of XAA-specific code
The DRI code attempts to use XAAGetCopyROP without checking whether XAA or EXA is in effect. This results in the server crashing with an undefined-symbol error when enabling EXA, then starting glxgears under GNOME/Metacity and attempting to drag the glxgears window.
The EXA code happens to have a functional duplicate of the required code under the name SavageGetCopyROP(). This patch moves the code to savage_accel.c where it is now shared between EXA and the DRI code.
It is disturbing that this has not been caught before.
