The old version of rrCreateSharedPixmap(), in addition to actually creating
a shared pixmap with scanout, also set up pixmap tracking on the source
driver.
I will be needing to create multiple shared pixmaps for PRIME double
buffering, so factor the part that does shared pixmap creation into its own
function, the new rrCreateSharedPixmap(). Rename the old
rrCreateSharedPixmap() to rrSetupPixmapSharing(), a function that
replicates the old functionality of rrCreateSharedPixmap() using the new
rrCreateSharedPixmap().
