POSIX explicitly states that the application must declare union semun.
This makes no sense, but it is what it is. This brings us into line
with Linux, MacOS/Darwin, and NetBSD.
In a ports exp-run a moderate number of ports fail due to a lack of
approprate autotools-like discovery mechanisms or local patches. A
commit to address them will follow shortly.

The source of error is a rounded increment being too large and thus the loop
steps slightly past 'last'. Perform a final comparison using the formatted
string values (truncated precision) to determine if we still need to print
the 'last' value.

With all values identical it was possible for Var() to return a negative
value due to limited floating point precision, resulting in "nan"
reported as Stddev.
Variance cannot actually be negative, so just return 0. We can later
investigate alternate algorithms for calculating variance to reduce the
effect of catastrophic cancellation here.

A subtle logic bug, probably introduced in r311895, caused tail to print the
first two lines of piped input in forward order, if the very first character

Summary:
r329077 caused gcc to emit uninitialized use warnings. Attempting to
fix those warnings yielded the following warnings:
usr.bin/tftp/main.c: In function 'main':
usr.bin/tftp/main.c:181: warning: variable 'el' might be clobbered by
'longjmp' or 'vfork'
usr.bin/tftp/main.c:182: warning: variable 'hist' might be clobbered by
'longjmp' or 'vfork'
This is a known bug in gcc, found at
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=24239
Work around that by simply marking hist and el as static.

Introduce WITH_/WITHOUT_LLVM_COV to match GCC's WITH_/WITHOUT_GCOV.
It is intended to provide a superset of the interface and functionality
of gcov.
It is enabled by default when building Clang, similarly to gcov and GCC.
This change moves one file in libllvm to be compiled unconditionally.
Previously it was included only when WITH_CLANG_EXTRAS was set, but the
complexity of a new special case for (CLANG_EXTRAS | LLVM_COV) is not
worth avoiding a tiny increase in build time.

If the interrupt count is very high (greater than ~42M), notably on one-shot
execution on long running systems, the intermediate multiplication step in the
rate calculation will overflow the width of a 32-bit architecture long (32
bits), causing the rest of the calculation to calculate with a truncated value,
and report very low rates (sometimes 0).

When building FreeBSD the makefiles invoke find with various flags such as
`-s` that aren't supported in the native /usr/bin/find. To fix this I
build the FreeBSD version of find and use that when crossbuilding.
Inserting lots if #ifdefs in the code is rather ugly but I don't see a
better solution.

Highlights of this update:
- /__local_fixups__ is now generated to be GPL dtc and libfdt compliant
- Compiling with -@ will now cause dtc to assign phandles to all labelled
nodes
- /include/ and /incbin/ now handle absolute paths correctly
- The manpage now has information about overlays, including how to apply
them and how to generate them
- Syntactic sugar for overlays is now supported, allowing an overlay DTS
like:
=
/dts-v1/;
/plugin/;
&foo {
foo,status = "okay";
};
=
to generate a fragment targetting <&foo>.
- The process stats are actually thread counts rather than process
counts.
- Simplify various descriptions to remove mention of stats that are
updated every 5 seconds (all VM related stats are now "instant",
only the load average is updated every 5 seconds).
- Don't make any mention of special treatment for processes that have
been active in the last 20 seconds. We don't track that stat.
- Rework the description of active virtual memory. Call it mapped
virtual memory and explicitly point out it is not the same as the
active page queue (which corresponds to "Active" in top(1)), and
also hint at the possible bogusness of the value (e.g. if a process
maps a single page out of a multiple GB file, the entire file's size
is considered mapped).
- Simplify a few descriptions that implied their output was a value
per interval. All of the "rate" values are per-second rates scaled
across the interval.
- Update a few comments for 'struct vmtotal' along similar lines.
