Provide C11 <uchar.h>.
OK millert@.
Tested by naddy@ in a bulk and by matthieu@ in the new foot(1) port.
I originally wrote the code in 2022 at the prodding of espie@.
Using one improvement to a manual page from jmc@.

Resolve a mandoc -Tlint warning about trailing whitespace.

More wide character string function man page improvements based on feedback
by Kaspars Bankovskis. ok jmc@

better wording, from andre smagin; ok stsp

oops, we forgot to remove the .El in previous; sorry stefan (though you
should have run this through mandoc -Tlint ;)

Cosmetic tweaks of wcrtomb(3) RETURN VALUES section. ok jmc

Use the fancy .In macro for includes. From Jan Klemkow. ok jmc schwarze

dispense with some wacky escape sequences;

convert to new .Dd format;

grammar;

major abi changes:

* introduce the mbstate_t typedef.
impacts gnu libiconv, which has already been taken care of.

* Prepare for mb stuff to really exist, replace macro MB_CUR_MAX with
an external variable __mb_cur_max (impacts libX11 and various ports).

* use mbstate in all the mb <-> wchar functions with state.
* add a stub iswctype function allowing some ports to compile.

bash and gdiff are missing wcscoll, and need to be told there's no i18n
until this is fixed.

Discussed and matthieu, otto, millert, kettenis, deraadt.

Major libc bump
