Casting return to (void) was used to tell lint that you intended

Casting the third argument to (char *) was used as the most generic

Add a static mask of prime id and allocate them at screen time,

This adds the initial prime support for dri2 offload. The main thing is
when we get a connection from a prime client, we stored the information
and mark all drawables from that client as prime. We then create all
buffers for that drawable on the prime device dri2screen.
Then DRI2UpdatePrime is provided which drivers can call to get a shared
pixmap which they can use as the front buffer. The driver is then
responsible for doing the back->front copy to the shared buffer.
prime requires a compositing manager be run, but it handles the case where
a window get un-redirected by allocating a new pixmap and pointing the crtc
at it while the client is in that state.
Currently prime can't handle pageflipping, so always does straight copy swap,
v1.1: renumber on top of master.
v1.2: fix auth on top of master.

For DRI2 in some offload cases we need to set a new pixmap on the crtc,
this hook allows dri2 to call into randr to do the necessary work to set
a pixmap as the scanout pixmap for the crtc the drawable is currently on.
This is really only to be used for unredirected full screen apps in composited

When randr notices a crtc configuration request for a slave device,
it checks if the slave allocated pixmap exists and is suitable,
if not it allocates a new shared pixmap from the master, shares
it to the slave, and starts the master tracking damage to it,
to keep it updated from the current front pixmap.
If the resize means the crtc is no longer used it will destroy
the slave pixmap.
This adds the concept of a scanout_pixmap to the randr_crtc object,
and also adds a master pixmap pointer to the pixmap object, along
with defining some pixmap helper functions for getting pixmap box/regions.
