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."

modified man(1):
- avoid double slashes when displaying man pages (got tired
of '/usr/share/man//cat1/man.0').
- got rid of __P() while working on it.
- incorporate some of my old notes explaining how manpath works into the
comments of the code itself.
- renamed some of the vars so that the code is consistent throughout
(and hopefully clearer and easier to understand)
- fixed relative man paths for multiple man pages (man did a chdir()
on the first man page it had to format --- this broke any remaining
relative path man pages left to process). save old directory and
fchdir() back to it after formatting.
- improved doc on "man -h" which does more than just whatis(1) [e.g.
"man -h fopen" prints the required include files and the prototypes
rather than just the one-liner you get with whatis(1)]
- manconf.c now fills in the "len" length field in the TAG/ENTRY
structures (man now uses len).

revise man.conf file reading stuff to return error on failure in
addentry/gettag (fka getlist) rather than just err()ing out. this
allows man(1) to call cleanup and delete its tmp files rather than
just leave them floating. revise other apps using this code
(makewhatis, apropos, catman, whatis) to expect this. also remove
__P on updated files.

Use uname(3) to determine MACHINE type.

The previous change didn't even compile due to a warning.
Also, fix the same core dump in the case where there are no `_build' lines.
These should probably both emit a warning, so the user knows what happened.

No more core dump if _crunch section is missing in man.conf

Don't rebuild the cat page if the time stamp is the *same*; this can happen
just because `make install' ran quickly.

Add catman.

while catman doesn't `work' properly yet, use snprintf() when creating the
man paths, and add man section 9. hopefully, this program will actually
work soon.
