uwe | wsemul_vt100: fix RI to not scroll outside of scroll region
This is the inverse (scroll down) of the problem reported and fixed
for IND (scroll up) in PR kern/11827 back in 2000.
We only have one call site for this, but still move this bit of code
into a separate wsemul_vt100_prevline function to make it symmetric
with wsemul_vt100_nextline. While here, make both take vt100base_data.

wsemul_vt100.c - make static everything that can be static
Externally, wsdisplay only needs wsemul_vt100_ops. Internally (as
vt100 emulation is split into several files) wsemul_vt100_subr.c needs
wsemul_vt100_reset().

Rename min/max -> uimin/uimax for better honesty.
These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.
HOWEVER! Some subsystems have
#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))
even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.
To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.
I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:
cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))
It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.
Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)

- drivers can use this by setting VCONS_LOADFONT and WSSCREEN_RESIZE

size
With this tou can:
wsfontload -N foo /usr/share/wscons/fonts/flori.816
wsconsctl -dw font=foo

(which are not in-tree yet but can be loaded as LKMs).
For this, split out that part of the state structure which is used
by the sharable code and include that in the original vt100 state.
This is only a query-replace and sed(1) job for now, it makes sense
to rearrange things a bit so that even more code can be changed --
will do so later.

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@.

drochner | Change the calling interface for text output (to the graphics driver)

drochner | First cut on a VT100 emulation.
It should be able to parse escape sequences up to VT300, but not everything
is implemented. Most notably, there is no font handling - all displayable
characters are handed to the graphics driver. To solve this, a serious
interface change to the graphics driver is needed (Unicode?).

wsemul_vt100_subr: complete the refactoring from 2010
In 1.20 refactoring, functions in this file were changed to accept a
pointer to the new base class instead of the full emuldata:
-wsemul_vt100_foo(struct wsemul_vt100_emuldata *edp, ...)
+wsemul_vt100_foo(struct vt100base_data *edp, ...)
but the argument name was not changed. While this saved on the diff
churn back then, it created a rather unfortunate situation where the
same emulation state variables are referred to differently in this
file and other vt100 emulation files. Complete that old change by
renaming the base class arguments to match the variable name used for
it in other files.
Same object code is generated.
