Don't set IFEF_MPSAFE unless NET_MPSAFE at this point

Because recent investigations show that interfaces with IFEF_MPSAFE need to
follow additional restrictions to work with the flag safely. We should enable it
on an interface by default only if the interface surely satisfies the
restrictions, which are described in if.h.

Note that enabling IFEF_MPSAFE solely gains a few benefit on performance because
the network stack is still serialized by the big kernel locks by default.

If config_cfattach_detach() returns an error, handle it instead of

Do a better job of reporting invalid numeric constants in arithmetic exprs.

For example, given $(( 08 + 1 )) (or similar) instead of reporting
"expecting end of expression"  - the generic error for parse failed,
which happened as this was parsed as $(( 0 8 + 1 )) because the 8
could not be a part of an octal constant, and that expr makes no sense -
instead say "unexpected '8' (out of range) in numeric constant: 08"
which makes the cause of the error more obvious.

NFC for valid expressions, just the error message (and the way the
error is detected).

PR/52828: Mark Johnston: makefs UFS2 lazy inode initialization is buggy

makefs(8) emulates UFS2 in performing lazy initialization of inode
blocks when allocating and writing inodes. However, it only ever
initializes one inode block at a time, which may be insufficient.
If so, a later initialization may clobber an inode, resulting in
an inconsistent filesystem.

hopefully workaround the irregularly "fork fails in init" problem.

if a pool is growing, and the grower is PR_NOWAIT, mark this.
if another caller wants to grow the pool and is also PR_NOWAIT,
busy-wait for the original caller, which should either succeed
or hard-fail fairly quickly.

implement the busy-wait by unlocking and relocking this pools
mutex and returning ERESTART.  other methods (such as having
the caller do this) were significantly more code and this hack
is fairly localised.

Fix a vulnerability in NPF, that allows whatever incoming IPv6 packet to
bypass a certain number of filtering rules.

Basically there is an integer overflow in npf_cache_ip: npc_hlen is a
8bit unsigned int, and can wrap to zero if the IPv6 packet being processed
has large extensions.

As a result of an overflow, (mbuf + npc_hlen) won't point at the real
protocol header, but instead at some garbage within the packet. That
garbage, is what NPF applies its rules on.

If these filtering rules allow the packet to enter, that packet is given
to the main IPv6 entry point. This entry point, however, is not subject to
an integer overflow, so it will actually parse the correct protocol header.

The result is: NPF read a wrong header, allowed the packet to enter, the
kernel read the correct header, and delivered the packet depending on this
correct header. So the offending packet was supposed to be kicked, but
still went through the firewall.

Simple example, a packet with:
packet +  0 = IP6 Header
packet +  40 = IP6 Routing header (ip6r_len = 31)
packet +  48 = Crafted UDP header (uh_dport = 7777)
packet + 296 = IP6 Dest header (ip6e_len = 0)
packet + 304 = Real UDP header (uh_dport = 6666)
Will bypass a rule of the kind "block port 6666". Here NPF reads the
crafted UDP header, sees 7777, lets the packet in; later the kernel reads
the real UDP header, and delivers it on port 6666.

Fix this by using uint32_t. While here, it seems to me there is also a
memory overflow: still in npf_cache_ip, npc_hlen may be incremented with
a value that goes beyond the mbuf.

Protect ifp returned from route_output_get_ifa surely

An ifp returned from route_output_get_ifa was supposed to be protected
by a returned ifa; if the ifa belongs to ifp, holding the ifa prevents
