8c475e0ba6 evictions: Limit the number of minor eviction surfaces to fit in RAM 
We allocate more surfaces than used in a single pass in order to stress
the eviction code between batches. The intent here is not to exercise
swapping, and we fail to check that there is enough swap+memory to hold
all our surfaces. So limit the number of surfaces we allocate to fit
into RAM, and then require that the number of surfaces we need for
testing is less than the number of surfaces we can allocate.

In preparation for userptr test we move the eviction logic
into a common file so it can be used from both test cases.
