WITH_INIT_ALL_ZERO and WITH_INIT_ALL_PATTERN are mutually exclusive.
The .error when they were both set broke makeman so demote it to a
warning (and presumably the compiler will fail on an error later on).
We could improve this to make one take precedence but this is sufficient
for now.

I've not removed the Er macro from one of the lists in example.9, however,
because it seems to be doing some special kind of magic. Let's leave it
there for now.
There are two options:
- WITH_INIT_ALL_ZERO: Zero all variables on the stack.
- WITH_INIT_ALL_PATTERN: Initialize variables with well-defined patterns.
The exact pattern are a compiler implementation detail and vary by type.
They are somewhat documented in the LLVM commit message:
https://reviews.llvm.org/rL349442
I've used WITH_INIT_ALL_* to match Microsoft's InitAll feature rather
than naming them after the LLVM specific compiler flags.
In a range of consumer products, options like these are used in
both debug and production builds with debugs builds using patterns
(intended to provoke crashes on use of uninitialized values) and
production using zeros (deemed more likely to lead to harmless
misbehavior or NULL-pointer dereferences).

Perhaps it made sense in 1998 (r32836), but now it feels a bit out of

- map those IPv4 / IPv6 socket options which exist in FreeBSD
+ most of them visually verified to have the same type/layout of arguments
+ not tested with linux programs to behave as intended
- be more human readable for known options which are not handled
- be more verbose for unhandled socket message flags we know about
- print the jail ID in linux_msg if run in a jail
- add possibility to print debug message about known missing parts only once
- add multiple levels of sysctl linux.debug:
1: print debug messages, tell about unimplemented stuff (only once)
2: like 1, but also print messages about implemented but not tested
stuff (only once)
3+: like 2, but no rate limiting of messages
- increase default linux debug level from 1 to 3
We are a lot more verbose in as we need to be (e.g. some of the IP socket
options which are the same, and share the same memory layout, and are
believed to work). The reason is that we have no good testsuite to test those
linux-bits. The LTP or other test suites like the python one, are not fully
up to the task we need. As such the excessive messages about emulated but not
tested socket options.
IMO any MFC (possible, but most probably not by me) should set the default
debug level to 1.

Provide a way to ask for an opaque version string for a locale_t, so
that potential changes in sort order can be detected. Similar to
ICU's ucol_getVersion() and Windows' GetNLSVersionEx(), this API is
intended to allow databases to detect when text order-based indexes
might need to be rebuilt.
The CLDR version is extracted from CLDR source data by the Makefile
under tools/tools/locale, written into the machine-generated Makefile
under shared/colldef, passed to localedef -V, and then written into
LC_COLLATE file headers. The initial version is 34.0.
tools/tools/locale was recently updated to pull down 35.0, but the
output hasn't been committed under share/colldef yet, so that will
provide the first observable change when it happens. Other versioning
schemes are possible in future, because the format is unspecified.

The former is intended for use in vmspace_exit(). The latter is to
encourage use of explicit loads rather than relying on the volatile
qualifier. This works better with kernel sanitizers, which can
intercept atomic(9) calls, and makes tricky lockless code easier to read
by not forcing the reader to remember which variables are declared
volatile.

LLVM's demangler supports more modern C++ constructs such as lambdas and
unnamed types, and is actively maintained. The command line tool is
usable as a drop-in replacement for GNU c++filt, or elftoolchain's
cxxfilt. The latter is still available by using WITHOUT_LLVM_CXXFILT, if
needed.

Since elftoolchain's cxxfilt is rather far behind on features, and we
ran into several bugs, add an option to use llvm-cxxfilt as an drop-in
replacement.
It supports the same options as elftoolchain cxxfilt, though it doesn't
have support for old ARM (C++ Annotated Reference Manual, not the CPU)
and GNU v2 manglings. But these are irrelevant in 2020.
Note: as we already compile the required libraries as part of libllvm,
this will not add any significant build time either.
