ck_rwlock: Migrate to 32-bit primitives and add a write_latch operation.
...
write_latch allows writers to prevent incoming read acquisitions from
succeeding while permitting write_lock operations to complete. This is
useful if multiple writers are cooperating in linearizing a non-blocking
data structure and allows for lock state to be copied by the write lock
holder safely.
In collaboration with Paul Khuong and Jaidev Sridhar.

The _mpmc suffix is not useful. I see little benefit to specializing

ck_bytelock: Fix deadlock for unslotted reader workloads.

ck_rhs: Add a read mostly mode.
...
Add a read-mostly mode, in which entries won't share cache lines with
associated datas (probes, probe_bound, etc).
This makes write operations slower, but make get faster.
