ck_bitmap: Drop _mpmc suffix and add union operation.

The _mpmc suffix is not useful. I see little benefit to specializing
the bitmap to begin with.

ck_bytelock: Fix deadlock for unslotted reader workloads.
...
There is an off-by-one for slot ID sizeof(bytelock->readers) + 1.
This patch fixes the handling of this slot ID. Based off a patch
submitted by Albi Kavo <albi.kavo@gma....>.

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.

ck_rhs: Add.
...
Introduce ck_rhs, a variant of ck_hs that uses the robin hood algorithm for
insertion, and backward shift delete for deletion.

ck_hs: Add improved support for delete-heavy workloads.

This borrows from a technique described by Purcell and Harris
in "Non-blocking hashtables with open addressing" technical report.
Essentially, every slot will have an associated local probe maxim,
including tombstones. Highly aggressive workloads may still require
occassional garbage collection.
