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."

- build common/* once, into a library, rather than recompiling each of
the files multiple times in the other subdirectories (saves about
10% on compilation time)

Fix compiler warnings (and an awful lot of annoying little bugs).

Back out the .PATH.c changes. The .depend problem (and others)
will be fixed using the new .NOPATH make feature instead.

YP -> NIS

.Nm does not need a dummy argument ("") before punctuation or

Make usage match manpage.

rev 1.18 un-covered some bugs:

1. add_interdomain and add_secure are optional... not all maps use these
keys. if we are unable to add them due to a YPERR_KEY (meaning they
are not being used), then we should not flag this as a general error.

2. if we have a failure (status <= 0) we unlink_db() the temp database
as part of error handling. but we should not overwrite our error
status code with the return value from unlink_db() because if the
unlink_db() works (likely true) than that success will wipe out our
error code and the calling yppush will think we worked.

yppush RPC is supposed to return yppush_status error/status codes
(e.g. YPPUSH_SUCC, YPPUSH_NOMAP, etc.).

Functions like yp_master, yp_order_host, yp_master_host, and
yp_match_host return YPERR-style error codes. YPERR-style error
codes do not directly correspond to yppush_status codes, so it
is a bad idea to just directly YPERR codes into the yppush return
status value (it causes failing yppush runs to print confusing
error messages).

Change ypxfr.c to convert the YPERR codes to YPPUSH codes.

Simplify ypdb_open() API and just use it for opening the DB for reading.

In add_secure(), change

Fix coverity ID 1709.

snprintf NUL terminates, so there is no need to explicitly do it afterwards

de__P, ANSIfy.

convert to use getprogname()

use "ypxfr" instead of __progname as ident arg to openlog
wrap all debug syslogs in #ifdef DEBUG (rather than just most of them)

don't call ypdb_close() until after we're finished using data returned
by a previous ypdb_*() operation. seems to fix a problem noted in [bin/8064]

Use syslog(3) to log debugging info, and only if we're compiled with
-DDEBUG.

fix broken case statement for "-C", also check to make sure we've got
