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.

private data.
We can set/get private data with the documented el_get() and
el_set() so there's no need for our local extensions, which
never received much use anyway.
While here, also re-arrange the call to term_init_arrow. This
was left over from r89735 but is not required anymore.
This changes reduce differences against NetBSD's libedit.

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

Allow a single process to control multiple ttys (for pthreads using _REENTRANT)
using multiple EditLine objects.

don't restart on EINTR, instead return NULL immediately. From Anon Ymous
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.

el.c 1.44, el.h 1.17, editline.3 1.53, histedit.h 1.31:
# add EL_GETFP, and EL_SETFP.
el.c 1.42, term.c 1.46, term.h 1.18, editline.3 1.52, histedit.h 1.29:
# - Add more readline functions, enough for gdb-6.5
# - Make el_get varyadic, and implement EL_GETTC.
# - XXX: the EL_SETTC api will change in the future.
Note: The latter change breaks the ABI of the el_get() function.

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.
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
time. However, the CTM-express is at part 6 of 34 for the CAM
changes, so I've not been able to do a build world with the CAM in the
tree with these changes. Shouldn't impact anything, but...
