decrementing rt_refcnt just after rtrequest1(9).
While here reduce the differences with rt_ifa_add(9). There's still
an ambiguity about rtrequest1(9)'s return value, but bluhm@ will
address that in a different diff.

might return a negative number; the return value of match_error()
which returns (-1). This was technically a bug, and it exists in 5.8,
but there is no impact because the error is correctly catched with the
returned non-NULL error string.

This does require perl 5.22 which is not yet in base, but it also doesn't need
to be run except when new unicode versions are released which shouldn't happen
until after perl is updated.

ST-506 support. Remove redundant 'precomp' variables/fields and rename
remaining few to 'features' to be consistant with the rest of the code.
Consensus that no ST-506 disks (requiring ISA cards, <120MB, usually
rife with bad sectors that can't be worked around) are still running
OpenBSD.

is freed when we no longer need it.
In this case both code paths are executed in process context and thus
serialized by the KERNEL_LOCK. Since we are adding a route entry to
the table in both cases, rtfree(9) will not actually free the entry
because it is still RT_VALID.

This will simplify upcoming conversions of rt_refcnt-- to rtfree(9).
Such conversions are needed for proper MP refcounting.

this was originally implemented by jmatthew@ last year, and updated
by us both during s2k15.
there are four data structures that need to be looked after.
the first is the bpf interface itself. it is allocated and freed
at the same time as an actual interface, so if you're able to send
or receive packets, you're able to run bpf on an interface too.
dont need to do any work there.
the second are bpf descriptors. these represent userland attaching
to a bpf interface, so you can have many of them on a single bpf
interface. they were arranged in a singly linked list before. now
the head and next pointers are replaced with SRP pointers and
followed by srp_enter. the list updates are serialised by the kernel
lock.
the third are the bpf filters. there is an inbound and outbound
filter on each bpf descriptor, ann a process can replace them at
any time. the pointers from the descriptor to those is also changed
to be accessed via srp_enter. updates are serialised by the kernel
lock.
the fourth thing is the ring that bpf writes to for userland to
read. there's one of these per descriptor. because these are only
updated when a filter matches (which is hopefully a relatively rare
event), we take the kernel lock to serialise the writes to the ring.
all this together means you can run bpf against a packet without
taking the kernel lock unless you actually caught a packet and need
to send it to userland. even better, you can run bpf in parallel,
so if we ever support multiple rings on a single interface, we can
run bpf on each ring on different cpus safely.
ive hit this pretty hard in production at work (yay dhcrelay) on
myx (which does rx outside the biglock).

load ifp->if_bpf into a local variable, test that, and pass it to bpf.
this is instead of instead of assuming ifp->if_bpf wont change between
checking it and passing it to bpf.

honour this setting and consider them level-triggered instead of `polarity
decided by the first driver to use it'.
Add explicit code to turn registration of edge-triggered interrupts 3 and 4
into level-triggered, if they were set up a level-triggered by the SRM.
Based upon a NetBSD diff which eventually got reverted in NetBSD. However,
it turns out this is necessary for the kernel to correctly run with serial
console on my Multia.

to the cast to unsigned, it fails the error test and returns a bogus partial
read to the caller, which is painful to debug.
