I would have preferred static inlines for bitmap_get_value8(),
bitmap_set_value8() and find_next_clump8() to make this as fast
as possible in the callers because I've personally worked with
an industrial application where the GPIO pins of a 74x164 are
written every 250 usec.

But apart from that I like this series a lot, thanks for working on it.
