LibC: Don't memset 0 mmap'd callocs
...
There is no reason to page everything in and the kernel already
guarantees that the memory is zeroed in mmap

LibC: Rewrite malloc
...
The old linked list allocator with power of two pool sizes was kinda
weird. Now we use 1MiB bitmap allocators for allocations <64KiB and
directly call mmap for larger allocations. This allows userspace to
actually free unused memory on `free` :)
