If MPIC happens to be a slave interrupt controller (as on Armada38x),
it should be attached after primary interrupt controller.
Thus BUS_PASS_ORDER_LATE was added to default BUS_PASS_INTERRUPT.
This change doesn't affect the cases when MPIC is standalone IC.

r290383 has changed how mbufs sent by divert socket are handled.
Previously they are always handled by slow path processing in ip_input().
Now ip_tryforward() is invoked from ip_input() before in_broadcast() check.
Since diverted packet lost all mbuf flags, it passes the broadcast check
in ip_tryforward() due to missing M_BCAST flag. In the result the broadcast
packet is forwarded to the wire instead of be consumed by network stack.
Add in_broadcast() check to the div_output() function. And restore the
M_BCAST flag if destination address is broadcast for the given network
interface.

This patch improves the boundary checks in busdma to allow more cases
using the regular page based kernel memory allocator. Especially in
the case of having a non-zero boundary in the parent DMA tag. For
example AMD64 based platforms set the PCI DMA tag boundary to
PCI_DMA_BOUNDARY, 4GB, which before this patch caused contiguous
memory allocations to be preferred when allocating more than PAGE_SIZE
bytes. Even if the required alignment was less than PAGE_SIZE bytes.
This patch also fixes the nsegments check for using kmem_alloc_attr()
when the maximum segment size is less than PAGE_SIZE bytes.
Updated some comments describing the code in question.

-c, -e, and -f flags; the -f testcase is largely stubbed out, pending
additional work to determine a good, deterministic descriptor.
Core file test support is coming soon--it requires a bit more effort
due to the fact that:
- coredumps can be disabled (kern.coredump=0).
- corefiles can be put in different directories than the current
directory, or be named something other than `<prog>.core`
(`kern.corefile`).

The zone_fini parameter also goes away. Previously no protocols (except
divert) supplied zone_fini function, so inpcb locks were leaked with slabs.
This was okay while zones were allocated with UMA_ZONE_NOFREE flag, but now
this is a leak. Fix that by suppling inpcb_fini() function as fini method

Bring in some bits from NetBSD and lift the restriction in uniq(1) that
-c cannot be used with the -d and -u options. This restriction seems
unnecessary and is supported at least by GNU, OpenBSD, and NetBSD. Lift
the restriction and simplify the show() logic a little bit to maintain
functionality when -c is provided with -d/-u.
Also with this change, -d and -u are now actually a mutually exclusive,
albeit valid, combination. Given that they both indicate opposite
behavior, uniq(1) will no longer output anything if both -d and -u are
supplied. This is in line with NetBSD as well as GNU.
Adjust the man page and usage() to reflect that -c is its own standalone
option.
