5c0a5a6627 mm/mempool: support memalign about mempool and mulitple mempool
The memalign is special to multiple mempool because multiple mempool
doesn't support split and shrink chunk operate. So When you alloc a
memory block and find an aligned address in this block, you need to
occupy 8 bytes before the address to save the address of the padding
size and pool to ensure correct use in realloc and free operations.
So we will use bit1 in the previous address of the address to represent
that it is applied by memalign.

e5394be881 mempool/multiple_mempool: add private member delta in multiple-mempool
This delta describes the relationship between the block size of each
mempool in multiple mempool by user initialized. It is automatically
detected by the mempool_multiple_init function. If the delta is not
equal to 0, the block size of the pool in the multiple mempool is an
arithmetic progressions, otherwise it is an increasing progressions.
