ck_hs: Add ck_hs_move operation.
...
This operation moves ownership from one hash set object
to another and re-assigns callback functions to developer-specified
values. This allows for dynamic configuration of allocation
callbacks and is necessary for use-cases involving executable code
which may be unmapped underneath the hash set.
The developer is responsible for enforcing barriers and enforcing
the visibility of the new hash set.

ck_elide: Adaptive elision semantics.
...
These come in the form of CK_ELIDE_ADAPTIVE_PROTOTYPE,
CK_ELIDE_LOCK_ADAPTIVE and CK_ELIDE_UNLOCK_ADAPTIVE.
Primarily pushing this for the few that are playing with
master.
This is inspired by Andi Kleen's work for adaptive behavior
in the Linux kernel's RTM locks implementation. There are
various differences in the state machine, however. Specifically,
the concept of a retry and a busy-wait has been unified due
to state machine simplification such that any exhausted busy-wait
cycle reverts to a forfeit (a busy-wait is a specialized retry).
Follow-up work will involve allowing for is_locked behavior
to yield what users expect, if called from with-in a transaction
through the wrapper. It is warned that this will come at a performance
penalty.
