Note that lld enables relro by default, so that we already had either
partial or full RELRO, depending on the state of the BIND_NOW knob.
Add a RELRO knob so that the option can be disabled if desired, and so
that builds using the GNU toolchain are equivalent to those using the
standard Clang/LLVM toolchain.

Prior to 9b6edf364eb0 WITHOUT_KERNEL_SYMBOLS split kernel debug data
into standalone debug files at build time, but did not install those
files. As of 9b6edf364eb0 it stopped splitting the debug data, leaving
it in the kernel and modules (the default kernel configs include
DEBUG=-g).
Revert 9b6edf364eb0 and introduce a new build-time SPLIT_KERNEL_DEBUG
knob, as some people rely on the pre-9b6edf364eb0 WITHOUT_KERNEL_SYMBOLS
behaviour and that was imp's original intent.

Use it instead of the existing ctf.h from OpenSolaris. This makes it
easier to use CTF in the core kernel, and to extend the CTF format to
support wider type IDs.
The imported ctf.h is modified to depend only on _types.h, and also to
provide macros which use the "parent" bit of a type ID to refer to types
in a parent CTF container.
No functional change intended.

Fixes: 9e5b0d9eac5b ("cross-build: Fix bmake bootstrap with glibc 2.34")
MFC after: 1 week
As of glibc 2.34, our unistd.h wrapper's inclusion of stdlib.h exposes
fragility in glibc's sys/wait.h and corresponding part of stdlib.h,
leading to "error: use of undeclared identifier 'WNOHANG'" and similar
errors when bootstrapping bmake.
Work around this by wrapping sys/wait.h to force stdlib.h's inclusion
first before it's implicitly included during the problematic window in
sys/wait.h.

A number of header files in sys/* have, going back to 7th Edition Unix
in 1979, reqiured other files (like sys/types.h) to compile. Likewise
the 4BSD networking code has had prerequisites. However, going back to
around the turn of the 21st century, other systems have made them be
independently include-able (wide-spread header include protection
post-dates 7th edition Unix by maybe 3 or so years judging from USENET
source postings). Start down the path of making them all independently
include-able by creating this test that fails buildworld when they are
not.
The file 'badfiles.inc' contains a list of the currently broken files
that cannot be included w/o any prerequisites. As files are fixed, 'make
badfiles.inc' should be re-run to remove them from the list. Note: All
files that start with an underscore are considered internal and not
tested.
Please note: once a file is removed from badfiles.inc, it must pass on
all architectures. Buildworld through at least the _includes target is
needed to ensure its working (though a buildkernel should also be done
on all architectures as well).
