heap buffer is used as output of GP and input of PP for Mali Utgard GPU. Size of heap buffer depends on the task so is a runtime variable. Previously we just create a large enough buffer as heap buffer. Now we add a heap buffer type to be able to increase the backup memory dynamically when GP fail due to lack of heap memory.
