8074676d2d EXA: Optimize the eviction scanning loop in exaOffscreenAlloc. 
Reduce the cost of the inner loop, by keeping a set of pointers to the
first and the last areas in the series, subtracting the cost of the first
area from the score, and adding the cost of the last area while walking
the list.  This commit also moves the scanning loop from exaOffscreenAlloc
into a separate function.

Idea by Michel Dänzer.

93d876891d EXA: Improve the algorithm used for tracking offscreen pixmap use. 
Replace the current score keeping algorithm with a rolling counter that's
incremented in ExaOffscreenMarkUsed, with the previous value being stored
in the area.  exaOffscreenAlloc uses the difference between the counter
value and the value in the area when deciding which area to evict.
It now also takes the size of the areas into account, and favors evicting
smaller areas.

The credit for these ideas goes to Michel Dänzer.

f2e310132f Add CreatePixmap allocation hints. 
These hints allow an acceleration architecture to optimize allocation of certain
types of pixmaps, such as pixmaps that will serve as backing pixmaps for
redirected windows.

3549a12823 EXA: Disable 1x1 pixmap fill optimization for drivers that handle pixmaps. 
This reverts commit 1365aeff54.

It defeated the optimization for drivers that don't provide a CreatePixmap
hook. The optimization makes no sense for drivers that do anyway, so disable
it for them completely.

ffb58f4fa8 exa: add hooks for drivers to take over pixmap allocation 
This adds hooks for the driver to access Create/DestroyPixmap and ModifyPixmapHe
ader.

It allocates a 0 sized pixmap using fb and calls the driver routine to do
work of allocating the actual memory.

ModifyPixmapHeader is mainly required for hooking the screen pixmap which
isn't create by normal methods
