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

Undo update of libedit 2016-02-27
Something in libedit appears to be causing breakage in lldb38.
The changes are not generally huge but they are suficient to
to justify reverting for now.

bin/sh has been taught about el_gets setting the count to -1
on error, so now we can partially revert r238173 to reduce
differences with NetBSD's implementation.
Unfortunately NetBSD's libedit handling of EINTR (Revision
1.44 in read.c + SIGWINCH fixes) still causes trouble in
bin/sh and other utilities and has to be avoided.

Our libedit has been diverging from the mainstream version
maintained in NetBSD. As a consequence it has been difficult
to do an appropriate MFV and we have been bringing only
partial updates.
Here we update most of the files to at least match the
version available in NetBSD's snapshot of 20091228. This
version was chosen because it still doesn't include wide
character support (UTF-8), which involves many changes and
new files.
From NetBSD's logs:
Dec 15 22:13:33 2006 - editline.3 el.c el.h histedit.h
add EL_GETFP, and EL_SETFP.

add EL_REFRESH for the benefit of readline
Sep 10 15:45:37 2008 - common.c el.c read.c refresh.c sig.c term.c term.h tty.c
Allow a single process to control multiple ttys (for pthreads using _REENTRANT)
using multiple EditLine objects.
Jan 18 12:17:24 2009 - el.c read.c readline.c

Feb 15 21:25:01 2009 - sig.c sig.h
in order for read() to return EINTR we need to use sigaction, not signal,
otherwise SA_RESTART is set.

{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.
