kbdcontrol.c: make pre-Unicode compatibility conditional
Support for the full range of Unicode character codes has been added
to the main keymap back in 2009, with compatibility shims added in
2011 (to support an older kbdcontrol command on a new kernel during
an upgrade from FreeBSD-8 to FreeBSD-9).
Unicode support for accented characters that are reached via dead key
combinations has been added just recently, again with compatibility
shims to allow all combinations of old/new kernel and old/new
kbdcontrol command to load and display the keymaps including the dead
key table. (But full Unicode in the dead key table requires both a new
kernel and kbdcontrol command.)
This commit makes the compatibility shims depend on the respective
compatibility ioctls (OGIO_KEYMAP, OPIO_KEYMAP, OGIO_DEADKEYMAP, and
OPIO_DEADKEYMAP) being defined in sys/kbio.h. This is true for all of
them in 13-STABLE, none in 12-STABLE (as of now), and will become
optional due to a follow-up commit to sys/kbio.h in -CURRENT.
This commit is the only part of review D38465 that should be merged
back to 12-STABLE and 13-STABLE.

makefs: emit NM records for all directory entries
We previously attempted to emit Rock Ridge NM records only when the name
represented by the Rock Ridge extensions would actually differ. We would
omit the record for an all-upper-case directory name, however Linux (and
perhaps other operating systems) map names with no NM record to
lowercase.
This affected only directories, as file names have an implicit ";1"
version number appended and thus always differ. To solve, just emit NM
records for all entries other than DOT and DOTDOT .
We could continue to omit the NM record for directories that would avoid
mapping (for example, one named 1234.567) but this does not seem worth
the complexity.

ifconfig: Fix configuring if_bridge with additional operating parameters
For clone create and rename operations, the interface name get back can be
different from the one passed to ioctl(). Use the interface name we get back
so that ifconfig will not return unexpected ENXIO.
From static code analysis, some device drivers (cxgbe, mlx4, mthca, and qlnx)
do not enter net epoch before lagg_input_infiniband(). If IPoIB interface is a
member of lagg(4) interface, and after returning from lagg_input_infiniband()
the receiving interface of mbuf is set to lagg(4) interface, then when
concurrently destroying the lagg(4) interface, there is a small window that the
interface gets destroyed and becomes invalid before infiniband_input() re-enter
net epoch, thus leading use-after-free.
Widen NET_EPOCH coverage to prevent use-after-free.
Different lagg protocols have different means and policies to process incoming
traffic. For example, for failover protocol, by default received traffic is only
accepted when they are received through the active port. For lacp protocol, LACP
control messages are tapped off, also traffic will be dropped if they are
received through the port which is not in collecting state or is not joined to
the active aggregator. It confuses if user dump and see inbound traffic on
lagg(4) interfaces but they are actually silently dropped and not passed into
the net stack.
Tap traffic after protocol processing so that user will have consistent view of
the inbound traffic, meanwhile mbuf is set with correct receiving interface and
bpf(4) will diagnose the right direction of inbound packets.

daemon: move variables into struct daemon_state
The fact that most of the daemon's state is stored on the stack
of the main() makes it hard to split the logic smaller chunks.
Which in turn leads to huge main func that does a a lot of things.
struct log_params existed because some variables need to be passed
into other functions together.
This change renames struct log_params into daemon_state

wpa_supplicant/hostapd: Fix uninitialized packet pointer on error
The packet pointer (called packet) will remain uninitialized when
pcap_next_ex() returns an error. This occurs when the wlan
interface is shut down using ifconfig destroy. Adding a NULL
assignment to packet duplicates what pcap_next() does.
The reason we use pcap_next_ex() in this instance is because with
pacp_next() when we receive a null pointer if there was an error
or if no packets were read. With pcap_next_ex() we can differentiate
between an error and legitimately no packets were received.

netlink: add snl(3) default parsers for routes and links.
This change adds the "default" parsers of _all_ route/link attributes

It removes the need to declare similar parsers in the userland applications,
simplifying their logic.
netlink: add rtsock-compatible header to use with netlink snl(3).
Some routing socket defines (`RTM_` and `RTA_` ones) clash with the ones
used by the the Netlink.
As some rtsock definitions like interface flags or route flags are used in
both netlink and rtsock, provide a convenient way to include those without
running into the define collision.

The cap_dns tests require Internet access. Currently they fail when

instead skip the tests if none of the non-casper name/addr lookups

To that end:
- Convert the tests to ATF so that skipping is easier to implement.
- Break up the tests into separate test cases.
- If one of the system (i.e., non-casper) lookup functions fails, skip
the test if all of them failed, otherwise fail the tests, since
partial failure indicates something is flaky and deserves a closer
look.
