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."

libarchive based frontends.

Don't depend on lubutil if we're building host tools. Fix tools build on
non-NetBSD hosts.

Complete the move of string_to_flags() and flags_to_string() from the
bin/ls sources to libutil:
o Bump libutil minor version number
o Fix uses to include <util.h> to pick up the function definitions
o Fix most uses of flags_to_string() to release the now-malloc()ed result

Don't compile in cpio usage, if we are SMALL.

sprinkle a little const, and now everything compiles with WARNS=3

PR/29005: Jesse Off: nbpax requires sys/mtio.h which doesn't exist on Interix
I added an ifdef called HAVE_MTIO_H and fixed the code to use it. It is
always defined now, but you can change this for Interix.

Welcome to WARNS=3

doc2html works here now, so remove NOHTML=
(not that it worked here, because NOHTML= was provided *after* <bsd.own.mk>...)

Now that <bsd.prog.mk> DTRT if HOSTPROG is defined (i.e, it is a no-op),
there's no need to special-case .include-ing it.

#ifdef HOSTPROG then explicitly use {major,minor,makedev}_netbsd
macros from pack_dev.h instead of the native versions.
Fixes [toolchain/20051] by Valeriy E. Ushakov.

don't need -lutil any more

don't bother with cpio/tar links or compat symlinks for HOSTPROGs

Install compatibility symlinks for /usr/bin/tar (-> /bin/tar)
and /usr/bin/cpio (/bin/cpio). The pathname of tar(1) is hard-coded
into things like binary packages, and thus must be kept around
for backward compatibility.

Flip the pax switch

fix previous: SMALLPROG w/o HOSTPROG still needs <bsd.prog.mk>. (hi christos)

don't support rmt for SMALLPROG

It doesn't help much to skip linking librmt if HOSTPROG but leave
all the librmt calls in the program. So, make librmt support conditional
on #ifdef SUPPORT_RMT, and define that when NOT building as a HOSTPROG.

merge OpenBSD changes:
- correct -C processing
- add ability to read filenames and flags from a file
- don't print dangerous escape sequences to the terminal
- use strlcpy/strncpy properly.
- handle tmpfile creation better.
- improve documentation of options.
- handle stdout/stderr list selection correctly.
- kill gzip when we get interrupted.
- simplify gzip setup.
- add more flags to programs.

additional changes:
- librmt processing.
- set POSIXLY_CORRECT in options parsing.
- prevent more string overruns.
- support -T

we don't turn the switch on to replace tar and cpio yet.

Use ${NETBSDSRCDIR}/some/path instead of ${.CURDIR}/../../some/path (etc).

make smaller if SMALLPROG is defined, not CRUNCHEDPROG; it's feasible
that a crunchgen(3)ed version of pax wants -USMALL ...

- don't compile in support for -M (mtree specfile input) or -N dbdir
(alternate directory for id info) if SMALL is defined
- enable -DSMALL and remove unused objects if CRUNCHEDPROG is defined
- minor cleanup in next_file() (preparation for future work)

Make almost all tools compile and run properly on non-NetBSD hosts. (In
particular, most tools now run correctly on Solaris 7.)

Do not .include <bsd.prog.mk> if building as a host tool.

Add '-N dbdir', to specify that user & group lookups (via pwcache(3)) are to
be done from dbdir/master.passwd and dbdir/group, using simple text file
parsing routines from ../../usr.sbin/mtree/getid.c.
This does not affect the -G and -U options, which always use the
system databases.

s/u_longlong_t/unsigned long long/ to shut up the parc port

Implement -M flag: During a write or copy operation, treat the list of
files on standard input as an mtree(8) `specfile' specification, and
write or copy only those items in the specfile.

If the file exists in the underlying file system, its permissions and
modification time will be used unless specifically overridden by the
specfile. An error will be raised if the type of entry in the specfile
conflicts with that of an existing file.

Otherwise, it is necessary to specify at least the following parameters
in the specfile: type, mode, gname or gid, and uname or uid, device
(in the case of block or character devices), and link (in the case of
symbolic links). If time isn't provided, the current time will be used.

- ansi KNF (just remove all the #ifndef __STDC__ prototype junk,
leaving the ansi stuff)
- use longlong_t instead of quad_t (etc), and rename *uqd*() -> *ull*()
- clean up the NET2_STAT stuff similar to ftpd; provide #defines and
macros which select which cast to use, etc
- clean up the NET2_FTS and NET2_REGEX #define use

Don't generate html yet. doc2html needs a fix.

Use the uid/gid caching moved into libc. Fixed a memory leak!

- implement -C and -l for pax-as-tar, as inspried by GNU tar.
- minor cleanups to the options parsing code.
- add a cpio frontend.

note: a few GNU/svr4 cpio options are not supported yet (#ifdef
notyet), however all x/open ones are.

CFLAGS->CPPFLAGS

Remove WARNS=1 from all the subdirectory Makefiles, and add it to Makefile.inc
now that all /bin has been cleaned.

- Rename local warn so tty_warn that we can include <err.h> since this program
uses err() and errx().
- Fix printf format strings.
- Added WARNS=1; note
- Added missing prototypes.
- Split overloaded trail function into trail() and subtrail().

convert to new RCS id conventions.

Whoever wrote the tar command line argument parsing code didn't realize
that the order of arguments is different if the command flags are specified
without a `-'. I've integrated getoldopt.c from John Gilmore's pdtar which
handles argument parsing correctly.
