vppinfra: add heap header in front of dlmalloc space
This patch adds smal header in front of dlmalloc space, and it stores
some additional information about the heap.
Immediate benefit of this patch is that we know the underlying page size
si we can display heap page statistics / real memory usage.
Type: improvement
