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.

introduce some common variables for use in GCC warning disables:

GCC_NO_FORMAT_TRUNCATION -Wno-format-truncation (GCC 7/8)
GCC_NO_STRINGOP_TRUNCATION -Wno-stringop-truncation (GCC 8)
GCC_NO_STRINGOP_OVERFLOW -Wno-stringop-overflow (GCC 8)
GCC_NO_CAST_FUNCTION_TYPE -Wno-cast-function-type (GCC 8)

use these to turn off warnings for most GCC-8 complaints. many
of these are false positives, most of the real bugs are already
commited, or are yet to come.


we plan to introduce versions of (some?) of these that use the
"-Wno-error=" form, which still displays the warnings but does
not make it an error, and all of the above will be re-considered
as either being "fix me" (warning still displayed) or "warning
is wrong."

Use the definitions from the standard header files and replace homebrew
snprintb with the libutil one.

Include a few additional libc functions in rump.route to make it work with inet6

getaddrinfo and if_nametoindex are newly added to interpret interface names
in IPv6 link-local addresses. if_nametoindex looks not used in rump.route,
but it is needed because it is used indirectly from getaddrinfo.

From s-yamaguchi@IIJ

Fix rump.{netstat,route} shows host's interface names in link local addresses

Interface names of IPv6 link local addresses are resolved
by getnameinfo(3). So we need to rump-ify it as well as
if_indextoname and getifaddrs.

Fix rump.route shows host's interface names

Let it use rump-ified if_indextoname and getifaddrs
to get rump kernel's interfaces, which is the same way
as ifconfig.

Factor out the netstat route printing code and use it here. There is no
point in having 2 different copies; fixes PR/49371

branches: 1.25.24;
Convert from RUMP_ACTION to RUMPPRG.

Support RUMP_ACTION to compile a rump kernel client.

Remove XNS and CCITT/X25 bits.

Only compile in IPv6 support if ${USE_INET6} != "no"

MKINET6 is for providing IPv6 infrastructure.
USE_INET6 is for compiling IPv6 support into the programs (needs MKINET6).

Use ${HOST_SH} instead of `sh'.

If necessary, pull in <bsd.sys.mk> to get the definition of HOST_SH;
Makefiles that pull in one of (most of) <bsd.*.mk> will get this anyway.

s/CFLAGS/CPPFLAGS/ for -D and -I.

IPv6-ready route command (-inet6 and -prefixlen are added)

CFLAGS->CPPFLAGS

Eliminate bogus redefinitions of standard targets.

- Add netatalk bits
- Add prototypes
- Fix printf formats

Now that non-superuser can open the routing socket, this program no
longer needs to be setuid-root. Superuser status is required to
alter the routing table, but is enforced by the kernel.

Note that distrib/utils/x_route uses these files.

As discussed some time ago, add a "show" sub-command.
Also allow compilation with -DSMALL to ommit support for
non-essential protocols (i.e. when built into a ramdisk).
Use a less hack-ish way to generate keywords.[ch] and just
check in the result (helps ../../distrib/utils/x_route).

route.o, not route, depends on keywords.h. from jhawk@mit.edu; pr 978

convert to new RCS Id conventions; reduce my headache

specify man pages the new way.

don't need that 'all' line.

need dep. first

Clean up import.

Add RCS identifiers.

Reenable building keywords.h dynamically.

Compile X.25, OSI, and NS code.

changed "Id" to "Header" for rcsids

added rcs ids to all files
