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 Change-Id: Ibd6989cc2f2f64630ab08734c9552e15029c5f3f Signed-off-by: Damjan Marion <damarion@cisco.com>
