MFC r238178, 238624, 238810:

Re-merge a couple of changes from NetBSD libedit.

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.

Also fix some warnings to be more in sync with NetBSD.

Merge changes from upstream libedit.

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.

Copy head to stable/9 as part of 9.0-RELEASE release cycle.

* 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.

Move terminal descriptor flush before stty to eliminate potential problems
whith characters conversion changed like \n -> \r\n and so on.

<blush> I tested the real code changes, but neglected to test the
insertion of $FreeBSD$. I miffed it (pointy hat please). Hopefully
no one will notice this short window where -current didn't compile.

Make comment match code forgotten in last commit

Add $FreeBSD$ so I can commit:

Remove extern int errno;. Instead include the ANSI <errno.h>. No
functional changes, just a higher level of pedantry.

Fixes assorted problems with the history edit functions in libedit. This
affects sh, ftp (and others?).
