Erik Eckstein e7b5843b33 runtime: add a StackAllocator utility ...

A StackAllocator performs fast allocation and deallocation of memory by implementing a bump-pointer allocation strategy.
In contrast to a pure bump-pointer allocator, it's possible to free memory.
Allocations and deallocations must follow a strict stack discipline.

In general, slabs which become unused are _not_ freed, but reused for subsequent allocations.
The first slab can be placed into pre-allocated memory.
