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.

bsd.own.mk: rename GCC_NO_* to CC_WNO_*

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_STRI

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."

config() in manconf.c now verifies _build (and _crunch) command
templates with fmtcheck(3) so annotate the printf that uses these
commands as safe with a __format_arg wrapper and drop
-Wno-format-non

config() in manconf.c now verifies _build (and _crunch) command
templates with fmtcheck(3) so annotate the printf that uses these
commands as safe with a __format_arg wrapper and drop
-Wno-format-nonliteral.

XXX: Using local wrapper for now, solving this in general would be
nice, but it raises namespace pollution issues.

XXX^2: catman(8) also uses manconf.c and uses _build and _crunch so it
can also benefit from this (but see above).

Use -Wno-format-nonliteral instead of blanket -Wno-format.
