Søren Sandmann Pedersen 788ccb9a8b Move miTrapezoids() into fb as fbTrapezoids()
The main consumer of trapezoids, cairo, is using the Trapezoids
request, which is currently implemented in the miTrapezoids()
function. That function splits the request into smaller bits and calls
lower level functions such as AddTrap.

By moving the implementation of the whole request into fb, we can
instead call pixman_composite_trapezoids() to do the whole request in
one step.

There are no callers of miTrapezoids in any of the open source
drivers, although exa and uxa have their own copies of the function.
