more low-hanging fruits for EBCDIC; notes:
...
• ord() new, From: Daniel Richard G. <skunk@iSKUNK.ORG>
‣ used in some places
• (c - '0') → ksh_numdig(c) # may take *x++ argument
• (c - 'A') → ksh_numuc(c) # may NOT take *x+= argument
‣ idem for ksh_numlc(c) and 'a'
‣ these need changing for EBCDIC
‣ add testsuite for this
• use macros more, they exist already often
• use digits_lc[foo] instead of ('0' + foo), especially for letters
• caught another ksh_eq case…
• also caught a maybe-UB overflow check, but we don’t have TIME_T_MAX ☹

ordinarily, lineno must be mksh_uari_t, but edit.c most of all isn’t ready,
...
so we mitigate a bit (in var.c mostly) and tweak another type already, and
add some checks (mksh_{,u}ari_t must fit into {,unsigned }long) and print
line numbers with %lu already

SECURITY: fix integer overflows related to file descriptor parsing
...
bug initially found by Pawel Wylecial (LP#1440685)
additional bug found and suggested fix by enh (elliott hughes)
This commit also renames struct ioword.flag to ioflag to disambiguate
it from other members named “flag”, changes it to an unsigned type,
and packs ioflag and unit into shorts each, to make the struct smaller
(aligned even: 16 bytes on 32-bit systems) and reviews some of the
code involved in fd handling, though there wasn’t much to be found.

• Completely overhaul prompt length calculation and

prompt display routines; make Emacs and Vi share
code, permitting reducing of duplication and code
removal as well as more consistent behaviour; put
some common code into shared helper functions, too
• New x_adjust() logic (Emacs mode): when determining
what portion of a line to render use a much more
sophisticated algorithm and try to fill up ⅔ of the
total screen width (with line and prompt both) also
as wished from Steffen Daode Nurpmeso

use a different approach to the $"…" problem:
...
take the states that may open a string, only permit them by virtue of
moving the code out of Subst: to handle $+" and $+' at all; then add
S[Q]BRACE to that
side benefits:
• clearer, cleaner code flow
• smaller code
• better “business logic” ☺
• defuses one heavy use of duff’s device a bit
