stats: memory heap counters
- Add counters for the main-heap
- Add additional counters per heap:
STAT_MEM_TOTAL
STAT_MEM_USED,
STAT_MEM_FREE,
STAT_MEM_USED_MMAP,
STAT_MEM_TOTAL_ALLOC,
STAT_MEM_FREE_CHUNKS,
STAT_MEM_RELEASABLE,
The per-heap counters are organised as a two dimensional vector.
total, used and free are directly available via symlinks.
