Martijn Dekker c828ea8d0d Fix typeset -u/-l on NetBSD
On NetBSD, for some reason, the wctrans(3) and towctrans(3) C
library functions exist, but have no effect; the "toupper" and
"tolower" maps don't even translate case for ASCII, never mind wide
characters. This kills 'typeset -u' and 'typeset -l' on ksh, which
was the cause of most of the regression test failures on NetBSD.
Fallback versions for these functions are provided in init.c, but
were not being used on NetBSD because the feature test detected the
presence of these functions in the C library.

src/cmd/ksh93/features/locale:
- Replace the simple test for the presence of wctrans(3),
  towctrans(3), and the wctrans_t type by an actual feature test
  that checks that these functions not only compile, but are also
  capable of changing an ASCII 'q' to upper case and back again.

src/cmd/ksh93/sh/init.c: towctrans():
- Add wide character support to the fallback function, for whatever
  good that may do; on NetBSD, the wide-character towupper(3) and
  towlower(3) functions only change case for ASCII.

TODO for ksh 93u+m
See the issue tracker:
https://github.com/ksh93/ksh/issues
Known bugs in ksh 93u+m 1.0.0-beta.1 (help is wanted to fix these):
* Memory leak when initialising associative array in subshell
https://github.com/ksh93/ksh/issues/94
* Command substitution botches output of non-waited-for child processes
https://github.com/ksh93/ksh/issues/124
* Intermittent coprocess hang on Debian/Ubuntu and Solaris
https://github.com/ksh93/ksh/issues/132
* Wrong typeset -p output after unsetting multidimensional array elements
https://github.com/ksh93/ksh/issues/148
* File descriptor is unexpectedly closed after exec in subshell
https://github.com/ksh93/ksh/issues/161
* printf %T date parsing: GNU-style "ago" date spec completely broken

substitution

https://github.com/ksh93/ksh/issues/193
* Re-allow building dynamic libraries
https://github.com/ksh93/ksh/issues/302
______
Fix regression test failures:
- There are some serious regression test failures on OpenBSD when ksh
is compiled with AST vmalloc disabled, so the system standard malloc(3)
is used. These probably represent real ksh93 bugs exposed by OpenBSD's
security hardening mechanisms.
- Several known memory leaks have their tests disabled in tests/leaks.sh
and are marked TODO. These need tracking down and fixing.
______
Fix currently known bugs affecting shell scripting. These are identified by
their modernish IDs. For exact details, see code/comments in:
https://github.com/modernish/modernish/tree/0.16/lib/modernish/cap/
- BUG_BRACQUOT: shell quoting within bracket patterns has no effect. This
bug means the '-' retains it special meaning of 'character range', and an
initial ! (and, on some shells, ^) retains the meaning of negation, even
in quoted strings within bracket patterns, including quoted variables.
- BUG_IFSGLOBS: In glob pattern matching (as in case or parameter
substitution with # and %), if IFS starts with ? or * and the "$*"
parameter expansion inserts any IFS separator characters, those characters
are erroneously interpreted as wildcards when quoted "$*" is used as the
glob pattern.
