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.
