Use the READ and WRITE macros to wrap memory accesses that could be in video
memory. Add MEMCPY_WRAPPED and MEMSET_WRAPPED macros to wrap memcpy and
memset, respectively.
Create fbPrepareAccess macros to call into the driver to set up the
wfbReadMemory and wfbWriteWemory pointers. Call these from fbGetDrawable and
fbGetStipDrawable.
Add the READ and WRITE macros, which expand to simple memory accesses for fb,
and calls through the function pointers for wfb.
Add fbFinishAccess macro to give the driver an opportunity to clean up. Add
calls to this in the appropriate places.
Get rid of almost all uses of these definitions. They're still defined for
delinquent out-of-tree drivers, and also for the Mesa build. As well as
for miinitext.c. But largely gone.
Add XSERV_t, TRANS_SERVER, TRANS_REOPEN to quash warnings.
Add #include <dix-config.h> or <xorg-config.h>, as appropriate, to all
source files in the xserver/xorg tree, predicated on defines of
HAVE_{DIX,XORG}_CONFIG_H. Change all Xfont includes to
<X11/fonts/foo.h>.
