smbus: allow child devices to be added via hints
This will allow to add slave drivers in the same fashion as for iicbus.
Also, allow other code to add a child device and set its 'addr' ivar.
The ivar can only be set if it's unset, it can not be changed.
That could be used, for example, by a platform driver that has
a precise description of the hardware and, thus, knows what drivers
can handle what slaves.
The slave auto-probing code is unsafe and broken because it uses
7-bit slave addresses. It's going to be removed.
Note: internally the driver uses address of zero as an unset address
while smbus_get_addr() returns it as -1 for compatibility reasons.
The address is expected to be unset only for children that do not
work with slaves like, for example, smb(4).

Currently, when tcp_input() receives a packet on a session that matches a
TCPCB, it checks (so->so_options & SO_ACCEPTCONN) to determine whether or
not the socket is a listening socket. However, this causes the code to
access a different cacheline. If we first check if the socket is in the
LISTEN state, we can avoid accessing so->so_options when processing packets
received for ESTABLISHED sessions.
If INVARIANTS is defined, the code still needs to access both variables to
check that so->so_options is consistent with the state.

In the TCP stack, the hhook(9) framework provides hooks for kernel modules
to add actions that run when a TCP frame is sent or received on a TCP
session in the ESTABLISHED state. In the base tree, this functionality is
only used for the h_ertt module, which is used by the cc_cdg, cc_chd, cc_hd,
and cc_vegas congestion control modules.
Presently, we incur overhead to check for hooks each time a TCP frame is
sent or received on an ESTABLISHED TCP session.
This change adds a new compile-time option (TCP_HHOOK) to determine whether
to include the hhook(9) framework for TCP. To retain backwards
compatibility, I added the TCP_HHOOK option to every configuration file that
already defined "options INET". (Therefore, this patch introduces no
functional change. In order to see a functional difference, you need to
compile a custom kernel without the TCP_HHOOK option.) This change will
allow users to easily exclude this functionality from their kernel, should
they wish to do so.
Note that any users who use a custom kernel configuration and use one of the
congestion control modules listed above will need to add the TCP_HHOOK
option to their kernel configuration.

Extract suffix rules into bsd.suffixes[-posix].mk.
Refactor make suffix rules into separate files (one for POSIX and one not),

[net80211] extend the ieee80211_rx_stats struct to include more information.
There are a variety of more interesting RX statistics that we should
keep track of but we don't. This is a starting point for adding more
information.
Specifically:
* now the RX rate information and some of the packet status is
passed up;
* The 32 bit or 64 bit TSF is passed up;
* the PHY mode is passed up;
* the "I'm decap'ed AMSDU!" state is passed up;
* number of RX chains is bumped to 4.
This is all mostly a placeholder for getting the data into the RX status
before we pass it up to net80211 - unfortunately we don't yet enforce
that drivers provide it, nor do we pass the provided info back up the
stack so anyone can use the data.
We're going to need to use some of this data moving forward.
Notably, now that some hardware can do AMSDU decap for us (the intel iwm
driver can do it when we flip it on; the ath10k port I'm doing does
it for us) then we need to pass it up through the stack so the duplicate
RX sequence numbers and crypto/IV details don't cause the packet to
be dropped and/or counted against a replay counter.
It's also the beginning of being able to do more interesting node
accounting in net80211. Specifically, once drivers start populating
per-packet rate information, AMPDU information, timestamps, etc,
we can start providing histograms of rate-versus-RSSI, account
for receive time spent per node and other such interesting things.
(Note: I'm also hoping to include ranging and RTT information for
future chipset support; and it's likely going to include it in
this kind of fashion.)
