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.

Add ${LIBUTIL} to DPADD.

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."

convert HAVE_GCC == 7 to HAVE_GCC >= 7.

- use -Wno-error=format-truncation

for 64 bit mips platforms where we built userland largely as n32 by
default, build a handful of tools as n64 so they work properly.

unfortunately, they're also static as dynamic n64 has a problem.

of these tools pstat is probably the lowest hanging fruit to convert
to sysctl. systat would be close were it not for the netstat screen,
which includes netstat itself.

the rest are difficult to perhaps foolish.


the upside is that netstat, pmap and fstat all work properly now.

When using -lcurses, you also need -lterminfo.
This fixes the build for sun2, and also builds with LDSTATIC=-static,
since archive libraries don't record inter-library dependencies.

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.

Include code to display per system call counts and times.

Update to use new kernel io statistics.

Add tape statistics.

WARNS=3

Add "df" display to give information about filesystems, available diskspace
and used disk capacity, similar to df(1):

Filesystem Avail Capacity
/0% /10% /20% /30% /40% /50% /60% /70% /80% /90% /100%
/ 359M |XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
/tmp 180M |
/home 146G |XXXXXXXXXXXXXXXX

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).

makefile delint. use NETBSDSRCDIR as appropriate

introduce puthumanint() which calls humanize_number(), and use to
display disk transfer values (Suggested by Simon Burge). Also clip
%busy to 100 and display as an int which has the useful side effect
of stopping it overflowing into the next column (100.0).

Remove check for sparc64 which adds -msoft-quad-float as that is now the
default for the compiler on sparc64.

use -msoft-quad-float on the sparc64.

Suggested by: Andy Doran <ad@mr-magoo.sports.gov.uk>
- inet6.ip6 and ipsec menu
- u_quad_t printing fix
- #ifdefs to allow compilation on 1.4.x

support IPv6. commands under "netstat" are IPv6 ready.
IPv6 is supported by filters (":ignore ssh") as well.
TODO: do something about line truncation?
TODO: inet6.icmp6? ":help" will not fit into single line...

Rototill global command matching -- switch from ad-hoc tomfoolery to a
table lookup. This will make prefix matching and so on easier.

Expect a similar change for mode-specific commands before too long.

While there, rename some structures with misleading names.

Watch this space for more changes soon.

- Add `bufcache' display which shows buffer cache usage per filesystem,
ala the monitor(1) command for Ultrix.
- Allow `h' or `?' to show the command list (same as `:help').
- Sort commands in cmdtab.c and systat.1

the PMAP_NEW option is gone as the new interface is no longer optional.

Add 4 new modes: ip, icmp, tcp, tcpsyn. XXX still some work to be done
on aesthetics and update modes.

also install as `sysstat'.
rationale: `nfsstat' is not `nfstat', and
other systems have a `sysstat' but not a `systat'.

completely remove Mach VM support. all that is left is the all the
header files as UVM still uses (most of) these.

Add a new `ps' view to systat, which shows process information. This
view is identical to the output of `ps aux' except that a.) the RSS and VSZ
fields are one character wider and b.) it shows a zero value for the RSS
and %MEM columns of processes which report a negative RSS.

Simply include -lcurses instead of -lcurses -ltermcap

add -DPMAP_NEW if PMAP_NEW is on in mk.conf

add -DUVM to CPPFLAGS if defined(UVM)

use CPPFLAGS instead of CFLAGS
