Log message:
Remove ptr_array from struct pf_ruleset
Each ruleset's rules are stored in a TAILQ called "ptr" with "rcount"
representing the number of rules in the ruleset; "ptr_array" points to an
array of the same length.
"ptr" is backed by pool_get(9) and may change in size as "expired" rules
get removed from the ruleset - see "once" in pf.conf(5).
"ptr_array" is allocated momentarily through mallocarray(9) and gets filled
with the TAILQ entries, so that the sole user pfsync(4) can access the list
of rules by index to pick the n-th rule during state insertion.
Remove "ptr_array" and make pfsync iterate over the TAILQ instead to get the
matching rule's index. This simplifies both code and data structures and
avoids duplicate memory management.
