ck_hp_fifo: Fix race condition on dequeue.
...
I accidentally swapped head/tail load in ck_hp_fifo (not in
ck_fifo, however). We must acquire head snapshot before tail snapshot.
An example execution history which could cause an incorrect update to occur
is below.
- tail <- fifo.tail / fifo.head != fifo.tail
- dequeue to empty (until final CAS which renders fifo.head = fifo.tail)
- head <- fifo.head / (head != tail)
- next <- fifo.head->next / next = NULL
- As head != tail, update to next pointer (where next is NULL).
However, if
- head <- fifo.head / (fifo.head != fifo.tail)
- dequeue to empty (until final CAS which renders fifo.head = fifo.tail)
- tail <- fifo.tail / fifo.head != fifo.tail
- next <- fifo.head->next / next = NULL
If we caught tail in final transition, the by the time we read next pointer,
head would have also changed forcing us to re-read. Thanks to Hendrik Donner
for reporting this.

ck_ht: Add support for per-hash-table allocator.
...
Documentation and regressions tests have been updated to reflect this.
This functionality allows for individual hash tables use to different
allocation functions. Thanks to Wez Furlong for pointing out the necessary
documentation update for ck_ht.
