bsd.own.mk: rename GCC_NO_* to CC_WNO_*

Rename compiler-warning-disable variables from
GCC_NO_warning
to
CC_WNO_warning
where warning is the full warning name as used by the compiler.

GCC_NO_IMPLICIT_FALLTHRU is CC_WNO_IMPLICIT_FALLTHROUGH

Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.

tftp: no longer need packed member warning

apply GCC_NO_ADDR_OF_PACKED_MEMBER

user.bin/tftp: Suppress -Werror=format-overflow error.

Add -Wno-error=format-overflow tftp.c to prevent build failure.

Error was reported when build.sh was run with MKLIBCSANITIZER=yes flag.

turn off various warnings for various things:

- file has looks bogus maybe-uninitialized
- llvm triggers an attribute violation:
ScheduleDAGInstrs.cpp:1430:14: error: declaration of
'llvm::raw_ostream& llvm::operator<<(llvm::raw_ostream&, const llvm::ILPValue&)'
with attribute 'noinline' follows inline declaration [-Werror=attributes]
- ntp and pkg_install have obvious restrict violations, should be
fixed but i'm avoiding patching upstream code in this pass
- tftp has an array bounds that doesn't seem real issue
- sysinst's partman.c has major problem with passing the same
string as source and dest in snprintf, as a way to strcat
with formatting which trip restrict violations. non trivial
to fix so for now the warning is elided.
- Xext's XEVI.c has similar issue as partman.c

everyone and GCC 8 gets these warnings turned off for now:

-Wno-format-truncation
-Wno-stringop-overflow
-Wno-stringop-truncation
-Wno-cast-function-type

as they trip a large amount of code. most of them should be
investigated, but the few i looked at were not finding actually
real bugs, vs instances of poor coding, so skipping for now.

branches: 1.9.20;
Add new Makefile knob, USE_FORT, which extends USE_SSP by turning on the
FORTIFY_SOURCE feature of libssp, thus checking the size of arguments to
various string and memory copy and set functions (as well as a few system
calls and other miscellany) where known at function entry. RedHat has
evidently built all "core system packages" with this option for some time.

This option should be used at the top of Makefiles (or Makefile.inc where
this is used for subdirectories) but after any setting of LIB.

This is only useful for userland code, and cannot be used in libc or in
any code which includes the libc internals, because it overrides certain
libc functions with macros. Some effort has been made to make USE_FORT=yes
work correctly for a full-system build by having the bsd.sys.mk logic
disable the feature where it should not be used (libc, libssp iteself,
the kernel) but no attempt has been made to build the entire system with
USE_FORT and doing so will doubtless expose numerous bugs and misfeatures.

Adjust the system build so that all programs and libraries that are setuid,
directly handle network data (including serial comm data), perform
authentication, or appear likely to have (or have a history of having)
data-driven bugs (e.g. file(1)) are built with USE_FORT=yes by default,
with the exception of libc, which cannot use USE_FORT and thus uses
only USE_SSP by default. Tested on i386 with no ill results; USE_FORT=no
per-directory or in a system build will disable if desired.

Fix old-style C code, update to WARNS=4.
Also, move file-scope .c extern decls to the .h file

__ss_{len,famiy} hack is no longer necessary

IPv6 support.
clarify a bit (specifically, routines in tftp.c now does not
modify "peeraddr")
