Instead of explicitly adding the pad bytes to force the structure an exact
multiple of cacheline size, let the PADDED_MEMBERS macro do the job.

cmap implements duplicates as linked lists, which causes removal of
rules to become (O^2) with large number of duplicates. This patch
fixes the problem by introducing a new 'counting' variant of the cmap
(ccmap), which can be efficiently used to keep counts of inserted hash
values provided by the caller. This does not require a node in the
user data structure, so this makes the user implementation a bit more
memory efficient, too.
