b318ab17d2 wcwidth: Classify some Hangul Jamo as combiners 
Hangul uses three codepoints to combine to one glyph. The first has a
width of 2 (like the final glyph), but the second and third were
assigned a width of 1, which seems to match EastAsianWidth.txt:

> 1160..11FF;N # Lo [160] HANGUL JUNGSEONG FILLER..HANGUL JONGSEONG SSANGNIEUN

Instead, we override that and treat the middle and end codepoint as combiners,
always, because there's no way to figure out what the terminal will
think and that's the way it's supposed to work.

If they stand by themselves or in another combination, they'll indeed
show up with a width of 1 so we'll get it wrong, but that's less
likely and not expressible with wcwidth().

Fixes #5729.

ecfe4acd0c complete: Do fuzzy match for --do-complete 
This only did prefix matching, which is generally less useful.

All existing users _should_ be okay with this since they want to
provide completions.

bfb61879cd Do create installation directories that already exist 
Reverts 71329a250b09dfacaca48fb69c69fe59eeb0c15a.

That tried to fix problems with pkgconfig by not recreating it.
Instead, use the function we already have for not trying too hard to
create a directory.

Fixes #5735.

2ae6e5a585 Explicitly handle all enum values in more switch statements 
This addresses a few places where -Wswitch-enum showed one or two missing
case's for enum values.

It did uncover and fix one apparent oversight:

$ function asd -p 100
   echo foo
end

$ functions --handlers-type exit
Event exit
asd

It looks like this should be showing a PID before 'asd' just like
job_exit handlers show the job id. It was falling
through to default: which just printed the function name.

$ functions --handlers-type exit
Event exit
100 asd

eaf496c1d4 seq.fish: use gseq if available. 
Apparently if you install gnu coreutils on OpenBSD, the tools are

provide our lousy shell script implementation.

25d83ed0d7104a2d95819463f835c5bced1ef864 (included in 3.0.0) added a `string` check that
did not use `--`, so negative numbers were interpreted as options.

Apparently nobody is using this.

2b0b3d3193 Outputter_t: Handle C locale like everything else 
This tried to skip conversion if the locale had MB_CUR_MAX == 1, but
in doing so it just entered an infinite recursion (because
writestr(wchar_t*) called writestr(wchar_t*)).

Instead, just let wcstombs handle it.

c633c06e11 Guess emoji width via system wcwidth 
Since Unicode 9, the width of some characters changed to 2.

Depending on the system, it might have support for it, or it might
not.

Instead of hardcoding specific glibc etc versions, we check what the
system wcwidth says to "😃", U+1F603 "Grinning Face With Big Eyes".

The intention is to, in most cases, make setting $fish_emoji_width
unnecessary, but since it sets the "guessed_emoji_width", that variable still takes precedence if it is set.

Unfortunately this approach has some caveats:

- It relies on the locale being set to a unicode-supporting one.
  (C.UTF-8 is unfortunately not standard, so we can't use it)
- It relies on the terminal's wcwidth having unicode9 support IFF the
  system wcwidth does.

This is like #5722, but at runtime.

The additional caveat is that we don't try to achieve a unicode
locale, but since we re-run the heuristic when the locale changes (and
we try to get a unicode locale), we should still often get the correct
value.

Plus if you use a C locale and your terminal still displays emoji,
you've misconfigured your system.

Fixes #5722.

```

and still takes 500ms to do so. The actual information is in a json
file, which we can't expect to read, and it doesn't have linebreaks or
such which we could use to hack-parse it.

So this is the best we can do for the most important bits (the
machineids), so let's just add this as-is.
