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.

Force at most partial RELRO for rump_server and related libraries

rump_server with -l uses lazy resolution by default and thus cannot be
used with full RELRO/BIND_NOW.

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: 1.14.10;
With the removal of HAVE_REGISTER_T from rumpuser_port.h, _KERNTYPES does not
need to be defined. This allows register_t to be typedef'd to RUMP_REGISTER_T
without conflict, as highlighted in PR kern/52206.

Revert previous change so builds can resume.
_KERNTYPES needs to be defined for NetBSD builds to succeed.
_KERNTYPES must not be defined for buildrum.sh builds to succeed.

Do not define _KERNTYPES as this breaks build with buildrump.sh due to
conflicting types for register_t.

Define _KERNTYPES for things that need it.

-I../librumpuser is still required for sp_common.c

use <rump/rumpuser_port.h>

Make it possible for external parties to specify additional dplibs.
This is useful for example on platforms which require -ldl.

branches: 1.7.4; 1.7.10;
need -I${.OBJDIR} now

create srcsys symlink

Remove "NOLINT" setting that was apparently committed by accident and
breaks the build.

Disable string aliasing for rump_syscalls.c. I can't figure out
how to otherwise make the kernel's register_t coreography to work
with the return value here in a MI fashion.

add some excuse of a manpage for librumpclient

branches: 1.2.2;
Install rumpclient to /lib to allow non-/usr users.

Add library for rump syscall client stubs.
