[PATCH v2 fixed 00/16] Ram blocks with resizable anonymous allocations under POSIX

We already allow resizable ram blocks for anonymous memory, however, they are not actually resized. All memory is mmaped() R/W, including the memory exceeding the used_length, up to the max_length. When resizing, effectively only the boundary is moved. Implement actually resizable anonymous
