This provides a framework to define a template describing
a set of "variables of interest" and the intended way for
the framework to maintain them (for example the maximum, sum,
t-digest, or a combination thereof). Afterwards the user
code feeds in the raw data, and the framework maintains
these variables inside a user-provided, opaque stats blobs.
The framework also provides a way to selectively extract the
stats from the blobs. The stats(3) framework can be used in
both userspace and the kernel.
See the stats(3) manual page for details.
This will be used by the upcoming TCP statistics gathering code,
https://reviews.freebsd.org/D20655.
The stats(3) framework is disabled by default for now, except
in the NOTES kernel (for QA); it is expected to be enabled
in amd64 GENERIC after a cool down period.

GCC uses "dynamic" TLS models when -fpic or -fPIC is explicitly
specified on the command line (which is only true for shared libraries).
It uses "static" (or "exec") TLS models otherwise. In particular, GCC
does _not_ use dynamic TLS models when PIC is implicitly enabled (which
it is on MIPS), only if a PIC flag is explicitly provided.
llvm uses "dynamic" TLS models if PIC is enabled either via a PIC flag
or if it is implicily enabled (as on MIPS64). This means that llvm on
MIPS64 always uses "dynamic" TLS models. However, dynamic TLS models
do not work for static binaries and libraries as the __tls_get_addr
function they invoke is only defined in rtld.

picobsd/tinyware has had this compact HTTPD server for a long time, and some
people do use it. Move it out into usr.sbin well in advance of any action
being taken on picobsd.
This has been gated behind an HTTPD option defaulted to *off*, primarily for
two reasons:
1.) This code likely needs a good audit, as it's been living off in picobsd
land for a long time, and
2.) We don't currently ship an httpd and this may not be a welcome surprise.

Summary: When powerpc64 switches to LLVM, use this patch to enable

https://reviews.llvm.org/D67190), because it determines ELF format
version based on endianness, which is incorrect.

Parts of the fusefs tests trigger a bug in current versions of llvm: IR
representation of some routine for the MIPS targets is a function with a
large number of arguments. This then leads the compiler on an hour+ long
goose chase, which is OK if you build the current tree but less-so if you're
trying external toolchain or doing a universe build involving mips when it
eventually gets switched over to LLVM.
Better, accurate details can be found in LLVM PR43263.

It does not help that gcc's implementation of this warning is even more
trigger-happy, in the sense that it already warns on the declaration
itself, not when you are using it. This is very annoying with our use
of -Wsystem-headers. That should really be disabled for gcc.
std::auto_ptr in a whole bunch of individual Makefiles, make the warning
globally non-fatal instead. This is similar to what was done to many
more non-fatal warnings from newer gcc versions.
Both clang and gcc development branches have reached version 10. Since we
only parse for a single digit in the major version number, this causes
COMPILER_VERSION to be set to its default of 0.0.0, meaning version checks
fail with these newer compilers.

This reworks my last commit in r301285 to more closely match what was in
r241298 (but reverted in r294878).
This is addressing "missing .meta file" rebuilds but also ensuring that
files are always generated when needed in each case.
Note that this is not a complete rework of the problem areas identified
in r301285 as most are "good enough" right now as the new pattern
is too verbose. It's only worth making this current change where headers
may be generated in the INCS list; where missing .meta file rebuilds are
spotted.
--- Technical details follow ---
Several attempts to deal with this problem of multi-output targets, with and
without META MODE, were explained in r241298, r294878, and r301285.
The general problem is with multi-output targets such as:
foo.c foo.h:
touch foo.c foo.h
foo.c foo.h:
touch foo.c
touch foo.h
foo.c foo.h: foo.in
./generator ${.ALLSRC}
This pattern is problematic in jobs mode as both files end up being
built concurrently and leads to races. With META MODE it is worse
as both targets end up rebuilding if they lack a .meta file. So the
generator is force built twice even though it is only needed once.
There are also problems in that 'make foo.h' may be ran before 'make foo.c';
The order of make generating the targets is not guaranteed.
An older attempted workaround to this (discussed in r294878) was:
foo.h: foo.c
foo.c: foo.in
./generator ${.ALLSRC}
This appears fine except that if foo.h is missing and foo.c exists then
foo.h will never be regenerated. This pattern is close to the solution
in this commit though:
foo.h: foo.c .NOMETA
.if !exists(foo.h)
foo.c: .PHONY .META
.endif
foo.c: foo.in
./generator ${.ALLSRC}
There's 2 differences here:
1. foo.h will never expect to have a .meta file since the foo.c target
will generate both and own the .meta file.
2. If foo.h does not exist then it needs to force foo.c to be rebuilt
with .PHONY. That normally disables META MODE though so .META is
given to tell bmake we do really expect a .meta file.
This pattern cannot work with implicit suffix rules since the .c and .h files
may be generated at different times (buildincludes vs depend/all).
