classify packets without a flowid into bucket 0, not a random bucket.

putting packets into random buckets means packets in a flow/connection
will be reorderd. pf assigns a flowid if it's enabled, and you need
pf to configure code, so it's reasonable to assume that most packets
will have a flowid. using bucket 0 like this is what we do in most
other places that bin packets with the flowid.

Provide pf queue manager API

Discussed with and OK henning@ at d2k17 as a part of a larger diff.

Fail with EINVAL when asked to create a non-root queue instead of panicking

Prompted by a bug report from semarie@, thanks!

clang warns on unused static const variables. Remove one such unused
variable so the kernel will build on arm64 again.

Export delay statistics instead of bucket information

Remove a leftover from the ifq_mfreeml conversion

Fix stage transition from the initial one to DROPPING

When the initial state is set to DROPPING, the code immediately
jumps to a CONTROL state bypassing DROPPING. To fix this we start
with an explicit INITIAL state so that we do an INITIAL->DROPPING
transition right off the bat in the beginning of the loop and
then perform a DROPPING->CONTROL and either CONTROL->DROPPING and
restart the loop or CONTROL->RECOVERY/ACCEPTING and terminate.
