Rework malloc. The new default implementation is based on dlmalloc from Doug
Lea. It is about 2x faster than the old malloc-930716, and behave itself much
better -- it will properly release memory back to the system, and it uses a
combination of brk() for small allocations and mmap() for larger allocations.
