wsconsctl: include correct header for lint

Running lint in non-tools mode picked up the header from the installed
system, not the one corresponding to the source code. The installed
header on NetBSD 9.99.88 does not define WSMOUSECFG_MAX yet.

Pass SED=${TOOL_SED:Q} in the environment to scripts run during the build.

Use ${TOOL_AWK} instead of ${AWK} or plain "awk" in make commands.

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 and use ${HOST_SH}

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".

move ${DEPENDSRCS} target to after .include <bsd.*.mk>

Use ${DEPENDSRCS} as a target instead of .depend, now that
<bsd.dep.mk> builds .depend from .dep files.

Move the inclusion of <bsd.prog.mk> up so that keysym.h can have ${DESTDIR}
properly in its dependency list.

Add 2004 to copyright notice as these has been significantly modified recently.

Do not show several variables when they are not available.

At the moment this only affects the display part, hiding console colors,
border color and/or console scrollback if their respective ioctls are
not supported by the running kernel.

Trying to write to these variables will still fail with the correct ioctl
error message.

Implement border color customization in wscons(4), only available for vga(4)
at the moment.

This includes the addition of two new wsdisplay ioctls, WSDISPLAY_{G,S}BORDER,
one to get the actual color and one to set it, respectively. Possible colors
match those defined by ANSI (and listed in wsdisplayvar.h).

It also adds two accessops to the underlying graphics device, getborder and
setborder, which mach their ioctl counterparts.

Two kernel options are added: WSDISPLAY_CUSTOM_BORDER, which enables the
ioctls described above (to customize the border color from userland after
boot), and WSDISPLAY_BORDER_COLOR, which sets the color at boot time.
The former is enabled by default on the GENERIC kernel, but not on INSTALL
(among others). The later is always commented out, leaving the usual black
border as a default.

wsconsctl is modified to allow accessing this value easily. For example,
'wsconsctl -d -w border=blue'.

Implement support to dynamically change wscons console and kernel colors.

Two new ioctls are added to the wsdisplay device, named WSDISPLAY_GMSGATTRS
and WSDISPLAY_SMSGATTRS, used to retrieve the actual values and set them,
respectively (the name, if you are wondering, comes from "message attributes").

A new emulop is added to the underlying display driver (only vga, for now)
which sets the new attribute for the whole screen, without having to clear
it. This is optional, which means that this also works with other drivers
that don't have this new operation.

Five new kernel options have been added, although only documented in
i386 kernels (for now):
- WSDISPLAY_CUSTOM_OUTPUT, which enables the ioctls described above to
change the colors dynamically from userland. This is enabled by default
in the GENERIC kernel (as well as others) but disabled on all INSTALL*
kernels (as this feature is useless there).
- WS_DEFAULT_COLATTR, WS_DEFAULT_MONOATTR, WS_DEFAULT_BG and WS_DEFAULT_FG,
which specify the default colors for the console at boot time. These have
the same meaning as the (already existing) WS_KERNEL_* variables.

wsconsctl is modified to add msg.default.{attrs,bg,fg} and
msg.kernel.{attrs,bg,fg} to the display part, so that colors can be changed
after boot.

Tested on NetBSD/i386 with vga (and vga in mono mode), and on NetBSD/mac68k.
No objections in tech-kern@.
