Vendor import nvi-2.1.2-c80f493b038 a multikey mapping fix

PR: bin/182463

Merge nvi-2.1.1 -> 2.1.2

Update nvi-1.79 to 2.1.1-4334a8297f

This is the gsoc-2011 project to clean up and backport multibyte support
from other nvi forks in a form we can use.

USE_WIDECHAR is on unless building for the rescue crunchgen. This should
allow editing in the native locale encoding.

USE_ICONV depends on make.conf having 'WITH_ICONV=YES' for now. This
adds the ability to do things like edit a KOI8-R file while having $LANG
set to (say) en_US.UTF-8. iconv is used to transcode the characters for
display.

Other points:
* It uses gencat and catopen/etc instead of homegrown msg catalog stuff.
* A lot of stuff has been trimmed out, eg: the perl and tcl bindings which
we could never use in base anyway.
* It uses ncursesw when in widechar mode. This could be interesting.

Fixes from NetBSD for nvi visual mode:

- Fix handling of ^@ when reading an ex command. Don't try to replay
the previous input.
- Fix handling of ^C in insert mode and when reading an ex command.
Repeating an interrupted input could cause a crash and interrupting
ex command input could cause a file corruption.
- Fix a bug which causes crashes in file name completion when a file
name is longer than the screen width.
- When an error occurs in v_txt(), leave the input mode.

- Sort the headers per style(9)

Reminded by: yar
Approved by: delphij (mentor, implicit)

- Fix crash with ncurses on FreeBSD/amd64 CURRENT by including missing
header <term.h>, which is required by both tputs() and tgoto().

Without this header, nvi crashes with the call to tputs() at line 114.
This is because the first argument of tputs() is a pointer, and the
returned pointer from tgoto() is casted to an integer by compiler.

For some reasons, this only crashes on amd64+CURRENT. On 6.x system,
this does not happen.

Merge rev 1.1.1.3 from vendor branch: fix refresh / warning deadlock

Merge rev 1.1.1.2 from the vendor branch: fix leftright scrolling for
long lines

Add $FreeBSD$ CVS Id tag so that I can merge rev 1.1.1.2 from the
vendor branch. This file was taken off the vendor branch in 1998,
before we started enforcing the presence of CVS Id tags. :-(

o nvi failed to correctly handle EINTR returned from tcsetattr(), exiting
instead of recovering, which happens in particular during a rapid series
of SIGWINCH's. This change forces nvi to loop on the call in the event
that the call is interrupted.

Interestingly, I submitted this bug report in 1998, and a solution was
posted shortly thereafter by Matthias Buelow; it's been sitting in the
PR database ever since.

Note: this takes this file off the vendor branch. If and when we find
a vendor for this code, the fix should be given back to them.

Close buffer overflow noted in security advisory DSA-085.
Submitted by: Koga Youichirou <y-koga@jp.FreeBSD.org>
Obtained from: Debian

Fix an underflow resulting from the assumption !O_ISSET(sp, O_LEFTRIGHT)
(ironically, the assumption is in a code block which is conditional on its
converse). This isn't strictly the correct fix; it's more of a workaround
to prevent an infinite loop. The correct fix (see
ports/editors/nvi-devel/files/patch-vi-relative r1.1) would take a file off
the vendor branch, but since the result for this version of nvi is
identical, this route was elected.

It is just stupid to have to do ``<ESC>!rm -f %'' to write a file you own.

This prevents any background sub-command executed from inheriting

Submitted by: kargl@troutmask.apl.washington.edu (Steven G. Kargl)

Bump default escapetime from 1 (ie: 100ms) to 3 (ie: 300ms). Hopefully
this will make it less likely to misinterpret arrow keys as seperate
keys when running over anything slower than a console.

This has been talked about for a while, I hope it's long enough but not
too long to be annoying.
