Allow pf to use dummynet pipes and queues.
We re-use the currently unused IPFW_IS_DUMMYNET flag to allow dummynet
to tell us that a packet is being re-injected after being delayed. This
is needed to avoid endlessly looping the packet between pf and dummynet.

Stop using the *NV version to retrieve states, as its performance is
unacceptably bad.
For 1,000,000 states the nvlist version needed ~100 seconds to retrieve
the states, the new version needs ~3 seconds.

This call is particularly slow due to the large amount of data it
returns. Remove all fields pfctl does not use. There is no functional
impact to pfctl, but it somewhat speeds up the call.
It might affect other (i.e. non-FreeBSD) code that uses the new
interface, but this call is very new, so there's unlikely to be any. No
releases contained the previous version, so we choose to live with the
ABI modification.

When we create an nvlist and insert it into another nvlist we must
remember to destroy it. The nvlist_add_nvlist() function makes a copy,
just like nvlist_add_string() makes a copy of the string.

This allows us to kill states created from a rule with route-to/reply-to
set. This is particularly useful in multi-wan setups, where one of the
WAN links goes down.

When parsing the nvlist for a struct pf_addr_wrap we unconditionally
tried to parse "ifname". This broke for PF_ADDR_TABLE when the table
name was longer than IFNAMSIZ. PF_TABLE_NAME_SIZE is longer than
IFNAMSIZ, so this is a valid configuration.
Only parse (or return) ifname or tblname for the corresponding
pf_addr_wrap type.
This manifested as a failure to set rules such as these, where the pfctl
optimiser generated an automatic table:
pass in proto tcp to 192.168.0.1 port ssh
pass in proto tcp to 192.168.0.2 port ssh
pass in proto tcp to 192.168.0.3 port ssh

pass in proto tcp to 192.168.0.5 port ssh

Allow up to 5 labels to be set on each rule.
This offers more flexibility in using labels. For example, it replaces
the customer 'schedule' keyword used by pfSense to terminate states
according to a schedule.

struct pf_rule had a few counter_u64_t counters. Those couldn't be
usefully comminicated with userspace, so the fields were doubled up in
uint64_t u_* versions.
Now that we use struct pfctl_rule (i.e. a fully userspace version) we
can safely change the structure and remove this wart.
