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.

new GCC_NO_* uses for warning issues. most of the users of the new
GCC_NO_RETURN_LOCAL_ADDR are bugs in GCC itself, not the code.

convert HAVE_GCC handling to modern GCC release numbering:
- HAVE_GCC=5 is now the default (vs. HAVE_GCC=53 we've been using for
GCC 5.4 and GCC 5.5.)
- remove some more GCC 4.8 code. we don't support GCC 4 here.
- adjust set lists to gcc=5 from gcc=53.

add some basic HAVE_GCC=6 handling (totally unused so far.)

branches: 1.14.6;
Disable a couple of warnings until further investigation.

branches: 1.13.2; 1.13.4; 1.13.6; 1.13.8;
Use positive checks for GCC 4.1. Deal with missing HAVE_GCC.

Change the conditional from >= 45 to != 4 to handle the non-gcc case.

Fix for gcc-4.1

branches: 1.10.2;
remove remaining makefile support for GCC < 45 that i found.

branches: 1.9.2;
ignore format errors for old gcc

Update warning flags to reflect the fixes. Restrict GCC flags to GCC.

Handle ancient vax gcc.

adjust for new ntp and add the generated man pages

branches: 1.5.2; 1.5.6; 1.5.8; 1.5.16;
cleanup last warnings, and remove local warnings overrides.

build libopts with WARNS=0 for now

merge import ntp-4-2-6p5

branches: 1.2.2;
- fixes for non-literal strings
- add missing strbuf initialization

initial version of reachover make- and support-files
