Now, if either source or dest were in framebuffer, try to get both
there, but prefer system memory for both otherwise. Required making
exaasync.c go through the try-acceleration path. This significantly
improves window resizing under composite, because previously the
pattern of creating a new pixmap and copying default contents from the
screen caused a fallback every time due to the new destination pixmap
being in system memory.
simplify/clarify it for driver writers who probably don't want to know
what pPixmap->devPrivate.ptr or pPixmap->devKind mean. Converts the sis
driver to use them, and bumps the EXA module minor version.
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>.
