Willy Tarreau e81248c0c8 BUG/MINOR: pool: always align pool_heads to 64 bytes 
This is the pool equivalent of commit 97ea9c49f ("BUG/MEDIUM: fd: always
align fdtab[] to 64 bytes"). After a careful code review, it happens that
the pool heads are the other structures allocated with malloc/calloc that
claim to be aligned to a size larger than what the allocator can offer.
While no issue was reported on them, no memset() is performed and no type
is large, this is a problem waiting to happen, so better fix it. In
addition, it's relatively easy to do by storing the allocation address
inside the pool_head itself and use it at free() time. Finally, threads
might benefit from the fact that the caches will really be aligned and
that there will be no false sharing.

This should be backported to all versions where it applies easily.
