MFC r343105: libedit: Avoid out of bounds read in 'bind' command

This is CVS revision 1.31 from NetBSD lib/libedit/chartype.c:
Make sure that argv is NULL terminated since functions like tty_stty rely
on it to be so (Gerry Swinslow)

This broke when the wide-character support was enabled in libedit. The
conversion from multibyte to wide-character did not supply the apparently
expected terminating NULL in the new argv array.

PR: 233343

MFC r340933:

libedit: improve multibyte support

Until this commit libedit only supported UTF-8 for multibyte charset
Improve it to support other multibyte charsets

Tested with eucJP and SJIS charsets.
Note that this change as been review and committed in upstream libedit
as well via christos@NetBSD

When MAKEOBJDIRPREFIX points to a case-insensitive file system, the
build can break when different source files create the same object
files (case-insensitivity speaking). This is the case for object
files compiled with -fpic and shared libraries. The former uses
an extension of ".So", and the latter an extension ".so". Rename
shared object files from *.So to *.pico to match what NetBSD does.

Also:
o Compile _Exit.c as C99_Exit.c, as it conflicts with _exit.s

libedit: Use correct buffer lengths in vi mode v command.

Libedit's vi mode provides a v command to edit the current line in vi(1)
(hard-coded to vi, in fact).

When Unicode/wide character mode was added, this command started truncating
and/or corrupting the edited text.

This commit fixes v if the text fits into the buffer. If the text is longer,
it is truncated.

- Hide _rl_qsort_string_compare() that should be private to libreadline()

* Add the readline(3) API to libedit. The libedit versions of
{readline,history}.h are in /usr/include/edit so as to not conflict with
the GNU libreadline versions. To use the libedit readline(3) one should
add "-I/usr/include/edit" to their Makefile
(spelled "-I${DESTDIR}/${INCLUDEDIR}/edit" within the FreeBSD source tree).

* Enable its use in the BSD licensed utilities that support readline(3).

* To make it easier to sync libedit development with NetBSD, histedit.h
is moved into libedit's directory as history shows shown we keep merging
it into that location.

libedit: Try to map <Delete> to ed-delete-next-char.

This adds a new "arrow" key "delete" corresponding to the kD termcap value.
It only works if that is a sequence such as "\033[3~"; if it is "\177", the
em-delete-prev-char or ed-delete-prev-char from the single-character
mappings remains. It turns out that most terminals (xterm and alikes,
syscons in xterm mode) produce "\033[3~" by default so <Delete> has the
expected effect.

This also means that things need to be considerably misconfigured for
<Backspace> to perform a <Delete> action.

libedit: Do not move the cursor for ed-delete-next-char in emacs mode.

This makes ed-delete-next-char suitable for mapping to the <Delete> key.

Behaviour in vi mode is unchanged (for 'x').

libedit: Reduce surprising behaviour with filename completion some more:
* Quote '*', '?' and '['. While it may be more useful to expand them to
matching pathnames, this at least matches with the completion we do.
* '@' is a regular character for filenames. Some other shells do
@<hostname> completion but we do not.
* Prefix names starting with '-' and '+' with './' so they are not seen as
options.

libedit: Allow simple quoting in filename completion.

The completer recognizes characters escaped with backslashes as being
literal parts of a word, and adds backslashes to avoid almost all
misinterpretation. In particular, filenames containing spaces can be
completed correctly.

For bug compatibility with the NetBSD version, the improved completion
function has a new name, _el_fn_sh_complete, and _el_fn_complete is
unchanged.

libedit: Fix a bug that could make completion listings incomplete.

sigset_t change (part 5 of 5)
-----------------------------

Most of the userland changes are in libc. For both the alpha
and the i386 setjmp has been changed to accomodate for the
new sigset_t. Internally, libc is mostly rewritten to use the
new syscalls. The exception is in compat-43/sigcompat.c

The POSIX thread library has also been rewritten to use the
new sigset_t. Except, that it currently only handles NSIG
signals instead of the maximum _SIG_MAXSIG. This should not
be a problem because current applications don't use any
signals higher than NSIG.

There are version bumps for the following libraries:
libdialog
libreadline
libc
libc_r
libedit
libftpio
libss

These libraries either a) have one of the modified structures
visible in the interface, or b) use sigset_t internally and
may cause breakage if new binaries are used against libraries
that don't have the sigset_t change. This not an immediate
issue, but will be as soon as applications start using the
new range to its fullest.

NOTE: libncurses already had an version bump and has not been
given one now.

NOTE: doscmd is a real casualty and has been disconnected for
the moment. Reconnection will eventually happen after
doscmd has been fixed. I'm aware that being the last one
to touch it, I'm automaticly promoted to being maintainer.
According to good taste this means that I will receive a
badge which either will be glued or mechanically stapled,
drilled or otherwise violently forced onto me :-)

NOTE: pcvt/vttest cannot be compiled with -traditional. The
change cause sys/types to be included along the way which
contains the const and volatile modifiers. I don't consider
this a solution, but more a workaround.

$Id$ -> $FreeBSD$

Fix MLINKS.

Noticed by: Norman C. Rice <nrice@emu.sourcee.com>

Add 2 functions: el_data_set() and el_data_get() which do what you
would expect. (Allow user data to be associated with an EditLine context).

As this changes no existing interfaces and doesn't alter any structs
visable to the user I've been told that its not necessary to bump
the version of the library.

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

Switch to using ".So" as the extension for PIC object files rather
than ".so". The old extension conflicted with well-established
naming conventions for dynamically loadable modules.

The "clean" targets continue to remove ".so" files too, to deal with
old systems.

On the alpha, sizeof(char*) != sizeof(int) which was assumed in
term_init(). This is the cause of /usr/bin/ftp faulting on the alpha.

Replace memory leaking instances of realloc with non-leaking reallocf.
In some cases replace if (a == null) a = malloc(x); else a =
realloc(a, x); with simple reallocf(a, x). Per ANSI-C, this is
guaranteed to be the same thing.

I've been running these on my system here w/o ill effects for some
