ck_bitmap: more bulk operations, less space, more tests
...
* new bulk rmw: intersection, intersection_negate (with complement),
* new bulk reads: empty, full, count, count_intersect
* ck_bitmap_iterator fixes: avoid out of bounds read on empty bitmaps,
and ck_bitmap_next is marginally faster on sparse bitmaps .
* less space: the bitmap itself is an array of unsigned int, which
eliminates alignment padding between the n_bit field and the bitmap.
* more unit tests.

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.
