552716dcff Implement enough of readline's 4.0 async mode to make gdb happy. This is 
not complete yet, but it seems to work...
This required to introduce an unbuffered mode to el_gets(), but that was
a minor change.

ec5dc2be24 Fix something that's been annoying me for a while... 
Pull in <fcntl.h>, so that the fcntl #defines are present, and we build in the
automatic reset of non-blocking mode, rather than beeping like mad.

4a97685c19 Fix problem with previous patches that broke vi history. 
- c_gets() was usually returning a length, but sometimes
  one of the CC_xxx values (which are small +ve integers)!
- fixed c_gets() by putting a ' ' under the cursor.

39f224af48 PR/18995: David Laight: libedit fixes for posix conformant sh 
The posix 'sh' specification defines vi-mode editing quite tightly.
The netbsd libedit code (used by sh to do this) was missing several
features, there were also minor errors in others.

Compare netbsd sh to the definition available from:
http://www.opengroup.org/onlinepubs/007904975/utilities/sh.html
In particular the following were not supported:
	U - undo all changes to line
	| - goto column
	Y - yank to end of line
	y - yank
	# - comment out current line
	@ - take input from shell alias [1]
	G - goto numbered line in history buffer
	v - edit history line with vi
	_ - append word from last input line
	. - redo last command
Other minor changes have also been made.

[1] This needs the shell to define an appropriate routine to
return the text of the alias.  There is no requirement that
such a function exist.

0e0ac6b723 - constify; passes all gcc and lint strict checks. 
- add config.h [Jason Evans], to create a portable version of libedit that
  can be easily compiled on other OS's.

3e32553f0b Fix PR7685 (gdb under emacs prints spurious ^M and messes up terminal) 
plus a few bogons noted along the way:
	1) Set EDIT_DISABLED if terminal type is emacs.
	2) fix bug in NO_TTY mode which caused it to not notice CR or LF
	3) implement EDIT_DISABLED within libedit to be somewhat like NO_TTY,
		except that a prompt is printed first.
