Fix host and network routes for new interfaces when net.add_addr_allfibs=0

sys/net/route.c
	In rtinit1, use the interface fib instead of the process fib.  The
	latter wasn't very useful because ifconfig(8) is usually invoked
	with the default process fib.  Changing ifconfig(8) to use setfib(2)
	would be redundant, because it already sets the interface fib.

tests/sys/netinet/fibs_test.sh
	Clear the expected ATF failure

sys/net/if.c
	Pass the interface fib in calls to rtrequest1_fib and rtalloc1_fib

sys/netinet/in.c
sys/net/if_var.h
	Add a fibnum argument to ifa_switch_loopback_route, a subroutine of
	in_scrubprefix.  Pass it the interface fib.

The PR reported that the old NFS server did not set uio_td == NULL
for the VOP_READ() call. This patch fixes both the old and new

Correct min/max cluster counts for FAT12/16/32

FAT12      1..4084

FAT32  65525..

This is required for interoperability with other FAT implementations,

Always define LIBLDNS. We don't need to only define it when it is
enabled.
LIBMILTER can be defined always. No need to restrict to only when
we're building sendmail.
Don't need to make these conditional on MK_LIBCPLUSPLUS. They can be
defined all the time without ill effect.
LIBUNBOUND can be unconditionally set.

    Teach the FreeBSD/beri boot to "auto-detect" whether argument 4 (a3) is a
    memory size of pointer to a struct bootinfo * by looking at its value and
    seeing whether it is pointer-like.  If a pointer, assume it's a bootinfo
    and extract memsize from it instead; otherwise, use it as memsize directly.
    This allows kernels to support bootinfo being passed by loader (and boot2)
    while still supporting older Miniboot setups.

    When the module metadata pointer is available from loader, use it in the

    In the BERI kernel boot code, extract 'boothowto' (which includes boot flags
    such as '-s') and 'envp' from passed module data.  Booting to single-user
    mode using boot flags now works.

Fix subnet and default routes on different FIBs on the same subnet.

These two bugs are closely related.  The root cause is that ifa_ifwithnet
does not consider FIBs when searching for an interface address.

sys/net/if_var.h
sys/net/if.c
	Add a fib argument to ifa_ifwithnet and ifa_ifwithdstadddr.  Those
	functions will only return an address whose interface fib equals the
	argument.

sys/net/route.c
	Update calls to ifa_ifwithnet and ifa_ifwithdstaddr with fib
	arguments.

sys/netinet/in.c
	Update in_addprefix to consider the interface fib when adding
	prefixes.  This will prevent it from not adding a subnet route when
	one already exists on a different fib.

sys/net/rtsock.c
sys/netinet/in_pcb.c
sys/netinet/ip_output.c
sys/netinet/ip_options.c
sys/netinet6/nd6.c
	Add RT_DEFAULT_FIB arguments to ifa_ifwithdstaddr and ifa_ifwithnet.
	In some cases it there wasn't a clear specific fib number to use.
	In others, I was unable to test those functions so I chose
	RT_DEFAULT_FIB to minimize divergence from current behavior.  I will
	fix some of the latter changes along with PR kern/187553.

tests/sys/netinet/fibs_test.sh
tests/sys/netinet/udp_dontroute.c
tests/sys/netinet/Makefile
	Revert r263738.  The udp_dontroute test was right all along.
	However, bugs kern/187550 and kern/187553 cancelled each other out
	when it came to this test.  Because of kern/187553, ifa_ifwithnet
	searched the default fib instead of the requested one, but because
	of kern/187550, there was an applicable subnet route on the default
	fib.  The new test added in r263738 doesn't work right, however.  I
	can verify with dtrace that ifa_ifwithnet returned the wrong address
	before I applied this commit, but route(8) miraculously found the
	correct interface to use anyway.  I don't know how.

	Clear expected failure messages for kern/187550 and kern/187552.

Add a SLEEP->SCAN transition.  Without this a disassociate or scan
request during SLEEP results in a hang.

Whilst I'm here, add in some disabled code that will transition to RUN
if there's multicast traffic.  It's not needed for Atheros hardware but
it may be for other hardware.
