ksh: suppress the 435 lint warnings about identifier list definitions

Leave the actual work of modernizing the function definitions to some
later day.

ksh: clean up Makefile

branches: 1.37.2;
adapt to ${CC_WNO_IMPLICIT_FALLTHROUGH}

Use ${CC_WNO_IMPLICIT_FALLTHROUGH} instead of
the older style more complex expressions.

all of this should be looked at closer, but some of them are not
very trivial.

Default to -Wno-sign-compare -Wno-pointer-sign for clang.
Push -Wno-array-bounds down to the cases that depend on it.
Selectively disable warnings for 3rd party software or non-trivial
issues to be reviewed later to get clang -Werror to build most of the
tree.

don't need -DHAVE_CONFIG_H here

Use ${HOST_SH} instead of `sh'.

If necessary, pull in <bsd.sys.mk> to get the definition of HOST_SH;
Makefiles that pull in one of (most of) <bsd.*.mk> will get this anyway.

Rework how MAKEVERBOSE operates:

* Don't bother prefixing commands with a line of ${_MKCMD}\
and instead rely upon "make -s". This is less intrusive on
all the Makefiles than the former. Idea from David Laight.

* Rename the variables use to print messages. The scheme now is:
_MKMSG_FOO Run _MKMSG 'foo'
_MKTARGET_FOO Run _MKMSG_FOO ${.TARGET}
From discussion with Alistair Crooks.

rework to use the newer _MKMSGCREATE (et al) macros

support MAKEVERBOSE

Rework how dependency generation is performed:

* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES.
This is a change of behaviour. If a Makefile wants the clean semantics
it must specifically append to CLEANFILES.
Resolves PR toolchain/5204.

* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS
that have a suffix of: .c .m .s .S .C .cc .cpp .cxx

* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES

* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}

* Deprecate the (short lived) DEPENDSRCS


Update the various Makefiles to these new semantics; generally either
adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing
specific .o dependencies with DPSRCS entries.

Tested with "make -j 8 distribution" and "make distribution".

default to WARNS=1 if not set

In foo="`echo \"hi\"`", the backslashes should be removed by the outer
double quotes, not seen by the inner backquotes. Previously, ksh(1)
handled this correctly in non-posix mode but incorrectly in posix mode.

The previous comments in src/bin/ksh/lex.c quote parts of some version
of the POSIX specification. The version of POSIX being quoted is not
identified, but the wording is very similar to that in SUSv3
<http://www.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html>.

It seems clear that the words "having escape characters removed"
mean, in that context, that the backslash before the double quote in
"...`...\"...`..." is removed as part of the handling of the outer
double quotes, so that the backslash is not present when the inner
backquotes are handled. The new code in this commit follows this
interpretation. The previous code followed a different interpretation
which is now believed to be incorrect.

In shell scripts invoked during a build, and in crunchgen, use ${AWK}
instead of plain "awk". The Makefiles that invoke these scripts
or programs will pass AWK=${HOST_AWK:Q}.

Homogenize usage messages: make the 'usage' word all lowercase, as this seems
to be the most common practice in our tree.
