* not used in tokenizer.c
* only use it for !NARROWCHAR
* no need for underscores before ct_{de,en}code_string()

longer needed now that we always compile with wide character support,
reducing code obfuscation.
OK czarkoff@ martijn@.
Diff also proofread by Christian Heckendorf <mbie at ulmus dot me>.
On first sight, it might look as if this required a bump because
it seems to change the public type el_rfunc_t. But we only compile
with WIDECHAR, and in that case, there is no change in the interface.
This also simplifies some logic by getting rid of the NARROW_READ flag
which was broken anyway.
OK czarkoff@
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.
OK czarkoff@
making the code more readable. Instead, provide an mbrtowc(3)
replacement function in chartype.[hc], files that encapsulate
such system dependencies anyway. No functional change.
OK czarkoff@
corruption reported by LEVAI Daniel <leva at ecentrum dot hu>. Also
rename "bytes" to "wlen" since bytes is not accurate, suggested by
stsp@.
