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."

branches: 1.16.46;
Use RUMPPRG.

ok Greg Oster

Update RUMP_ACTION to use rumpclient.

The server must of course have some disks configured. Let's say
we have this simple server with disks as a few sparse host files:

main()
{
rump_init();
rump_pub_etfs_register("/disk1", "./disk1.img", RUMP_ETFS_BLK);
rump_pub_etfs_register("/disk2", "./disk2.img", RUMP_ETFS_BLK);
rump_pub_etfs_register("/disk3", "./disk3.img", RUMP_ETFS_BLK);
rump_pub_etfs_register("/disk4", "./disk4.img", RUMP_ETFS_BLK);
pause();
}

And we run the server:

mainbus0 (root)
Kernelized RAIDframe activated
/disk1: hostpath ./disk1.img (97 GB)
/disk2: hostpath ./disk2.img (97 GB)
/disk3: hostpath ./disk3.img (97 GB)
/disk4: hostpath ./disk4.img (97 GB)

We can then configure the raid against the server:

> ./raidctl -c theraid.conf raid0

And lo, we have evidence of a level1 raid in the server dmesg:

raid0: RAID Level 1
raid0: Components: /disk1 /disk2 /disk3 /disk4
raid0: Total Sectors: 409599744 (199999 MB)

yea, i initialized it already in a previous run:

> ./raidctl -S raid0
Reconstruction is 100% complete.
Parity Re-write is 100% complete.
Copyback is 100% complete.

close rump kernel file descriptors properly

Support RUMP_ACTION, i.e. compile-time switch to make this execute
rump syscalls to configure raidframe in a rump kernel.

Move WARNS=3 to the Makefile.inc, and add a little const to the remaining
programs that did not compile before.

Kill __P(), use ANSI function declarations; WARNS=3.

WARNS=2 is the default defined in sbin/Makefile.inc. (thanks wiz)

Remove cruft. We no longer need to look into sys/dev/raidframe to
find the needed include files.

Move parts of a RAID type mapping table from rf_layout.c to rf_configure.c.
This means we don't need to compile or link with rf_layout.c here.

Build with WARNS=2.

Move two functions from rf_strutils.c into rf_configure.c, removing
the need for rf_strutils.c.

Move COPTS to CPPFLAGS. Nuke some no-longer needed compile options.

Add missing NetBSD RCS ID's! Thanks to SAITOH Masanobu (msaitoh@netbsd.org)
for pointing this out.

no need for CWARNFLAGS; ../Makefile.inc sets WARNS=1

Allow CFLAGS to be set in /etc/mk.conf

RAIDframe, version 1.1, from the Parallel Data Laboratory at
Carnegie Mellon University. Full RAID implementation, including
levels 0, 1, 4, 5, 6, parity logging, and a few other goodies.
Ported to NetBSD by Greg Oster.

raidctl is our userland configuration tool for RAIDframe.
