delete the "private" and "public" preprocessor macros, just use standard C;
OK martijn@

Clean up chartype.h:

* not used in tokenizer.c
* only use it for !NARROWCHAR
* no need for underscores before ct_{de,en}code_string()
* make the conversion buffer resize function private

OK martijn@

get rid of the non-standard data type "Char" in almost all files;
ok martijn@

Move wrapper macros to the two files actually needing them:
FUNW, Strlen, Strdup, Strcmp, Strncmp, Strncpy, Strncat -> history.c
Strchr, tok_strdup -> tokenizer.c
FUN, TYPE, STR -> both of these files

OK martijn@

Also proofread by Christian Heckendorf <mbie at ulmus dot me>
who reported some whitespace issues in parse.c.

Cleanup of standard header inclusion:

1. Add the missing <errno.h> to sig.c.
2. Do not include standard headers from private headers "chared.h"
and "el.h", include them directly where needed.
3. Delete a few needless inclusions of <ctype.h>.
4. Sort the standard headers.
5. Delete _GNU_SOURCE weirdness from histedit.h, that file doesn't even
need the access to wcsdup(3) mentioned in the comment.
6. Delete some trailing blanks and blanks before tabs.

Fix the same bug again that was already fixed in:
OpenBSD tokenizer.c rev. 1.8 2003/08/11 18:21:40 deraadt
Don't increase amax on realloc() failure.
The original fix got lost in a merge along the way.
This fix from Christos Zoulas via NetBSD tokenizer.c rev. 1.23 2016/02/15.

Fifth step in synching with NetBSD:
Delete the silly ptr_t and ioctl_t typedefs
and delete some "#ifdef notdef" code from "sys.h".
No functional change.
This makes hist.h identical to the NetBSD version.
It reduces the remaining diff from +1526 -734 to +1430 -592.
OK czarkoff@

Fourth step in synching with NetBSD:
KNF: Remove parentheses from return lines. No object change.
This makes emacs.c and prompt.c identical to the NetBSD versions.
It reduces the remaining diff from +2053 -1261 to +1526 -734.
OK czarkoff@

Remove non-exposed malloc/realloc/free wrappers, and then substitute
reallocarray() where it helps.

Update libedit to bring it into sync with the latest version from NetBSD.

rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and
unmaintainable). these days, people use source. these id's do not provide
any benefit, and do hurt the small install media
(the 33,000 line diff is essentially mechanical)

Sync libedit to NetBSD libedit as of Nov 8, 2003.
Tested by jmc@ djm@ and myself

Update to NetBSD libedit (from Oct 1, 2003), adding some string
cleaning and history bug fixes. The code includes GNU libreadline
functionality, but the corresponding header files are not installed,
since some libreadline functions are missing. There are some minor API
changes, notably:

old: EditLine *el_init(const char *, FILE *, FILE *);
new: EditLine *el_init(const char *, FILE *, FILE *, FILE *);

old: HistEvent *history(History *h, int op, ...);
new: int history(History *h, HistEvent *ev, int op, ...); plus some
changes in operation names. See editline(3) for details.

Tested by djm@, mouring@, jmc@.

failure to deal with realloc nicely; spotted by Jonas.Munsin@teleste.com,
few more changes by millert

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

is -Wall clean by making rcsid const

Part one of userland __P removal. Done with a simple regexp with some minor hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.

deal with realloc/malloc failure and don't trash old pointer if realloc fails

fix el_source() - a block needed braces around it (from NetBSD)
Some strcpy() -> strncpy (from NetBSD)
Some KNF
Add current NetBSD tags

Merge in NetBSD libedit changes and new man pages. Also fix some
strncpy() usage in their code. NetBSD change log was:
* add a man page for the editline routines
* add a man page describing editrc
* fix bugs in el_parse():
* didn't execute command when program name matched (test reversed)
* was checking against empty string instead of program name
* after checks, command to run also pointed to empty string
* document ^char and \ escape sequences
* when parsing ^char control chars, check the correct char when determining
validity (previously, ^char was a NOP interpreted as the literal string
because of this bug)
* Implement CC_REDISPLAY, which (unlike CC_REFRESH) redraws the entire input
* line (a la ^R). This is useful if the binding outputs information and
* mucks up the input line. To be used in ``list-choices'' bindings (refer
* to the ^D binding in csh when filec is set)
