Add a stat counter to track ipv6 atomic fragments. Atomic fragments can be
generated in response to invalid path MTU values, but are also a potential
attack vector and considered harmful (see RFC6946 and RFC8021).
While here add tracking of the atomic fragment counter to netstat and systat.

Experimentally, reduces sort -R time of a 148160 line corpus from about
3.15s to about 0.93s on this particular system.
There's probably room for improvement using some digest other than md5, but
I don't want to look at sort(1) anymore. Some discussion of other possible
improvements in the Test Plan section of the Differential.

Bound input file processing length to avoid the issue reported in [1]. For
simplicity, only allow regular file and character device inputs. For
character devices, only allow /dev/random (and /dev/urandom symblink).
32 bytes of random is perfectly sufficient to seed MD5; we don't need any
more. Users that want to use large files as seeds are encouraged to truncate
those files down to an appropriate input file via tools like sha256(1).
(This does not change the sort algorithm of sort -R.)

There's no reason to order based on strcmp of ASCII digests instead of
memcmp of the raw digests.
While here, remove collision fallback. If you collide two MD5s, they're
probably the same string anyway. If robustness against MD5 collisions is
desired, maybe we shouldn't use MD5.
None of the behavior of sort -R is specified by POSIX, so we're free to
implement this however we like. E.g., using a 128-bit counter and block cipher
to generate unique indices for each line of input.

CXXSTD was added as the C++ analogue to CSTD.
CXXSTD defaults to `-std=c++11` with supporting compilers; `-std=gnu++98`,
otherwise for older versions of g++.
This change standardizes the CXXSTD variable, originally added to
googletest.test.inc.mk as part of r345203.
As part of this effort, convert all `CXXFLAGS+= -std=*` calls to use `CXXSTD`.
Notes:
This value is not sanity checked in bsd.sys.mk, however, given the two
most used C++ compilers on FreeBSD (clang++ and g++) support both modes, it is
likely to work with both toolchains. This method will be refined in the future
to support more variants of C++, as not all versions of clang++ and g++ (for
instance) support C++14, C++17, etc.
Any manual appending of `-std=*` to `CXXFLAGS` should be replaced with CXXSTD.
Example:
Before this commit:
```
CXXFLAGS+= -std=c++14
```
After this commit:
```
CXXSTD= c++14

r344504 added an extra ARP_LOG() call in case of an if_output() failure.
It turns out IPv4 can be noisy. In order to not spam the console by default:
(a) add a counter for these events so people can keep better track of how
often it happens, and
(b) add a sysctl to select the default ARP_LOG log level and set it to
INFO avoiding the one (the new) DEBUG level by default.
Claim a spare (1st one after 10 years since the stats were added) in order
to not break netstat from FreeBSD 12->13 updates in the future.

This change is made in the name of GNU patch compatibility. If GNU patch is
fed a zero-length patch, it will exit successfully with no output. This is
used in at least one port to date (comms/wsjtx), and we break on this usage.
It seems unlikely that anyone relies on patch(1) calling their completely
empty patch garbage and failing, and GNU compatibility is a plus if it helps
with porting, so make the switch.
