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.

Fix build; clean manpages only if they are generated automatically.

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: 1.7.6; 1.7.8; 1.7.10; 1.7.24; 1.7.32; 1.7.34;
adjust for new ntp and add the generated man pages

branches: 1.6.2; 1.6.6; 1.6.8; 1.6.16;
merge import ntp-4-2-6p5

branches: 1.5.4;
Don't copy ntpq.1 to ntpq.8 before overwriting it.

"foo > bar" fails when bar is mode 444, and files copied from the
source tree should be expected to perhaps be read only. However, the
copy should have been removed when the sed was added. And, it never
should have been "@"; suppressing it made debugging this harder than
it should have been.

clean up man files copied during build

also.. while we are putting the pages into different sections,
lets change the manpage contents to reflect that

branches: 1.3.2;
Another addition of -lterminfo after -ledit, so this links statically as well.

add installation of manual pages, html files and up to now missing commands (sntp, ntptrace)

initial version of reachover make- and support-files
