It is autumn again and there is a new Unicode version 16.0.
The following patch updates our Unicode stuff in contrib, libcpp and
libstdc++ from that Unicode version.

* unicode/README: Update glibc git commit hash, replace
Unicode 15 or 15.1 versions with 16.

150100 in _GLIBCXX_GET_UNICODE_DATA test.
* unicode/from_glibc/utf8_gen.py: Updated from glibc

The following patch (in plaintext just a pseudo-patch where I've left out
the too big parts of either wget downloaded or regenerated files out with
..., full patch attached compressed) updates to Unicode 15.1 from 15.0
we had last year. Apparently Unicode forgot to add a new range to 4-8 Table
we are using, but from the other files it is clear what should have been
added; I've filed a bugreport against Unicode.

Updates cpp_wcwidth() to Unicode 15, following the procedure in
contrib/unicode/README mechanically without incident.

The procedure detailed in contrib/unicode/README was followed with nothing
notable coming up. The glibc scripts did not require any update, so the
only change was retrieving new versions of the Unicode data files and
rerunning gen_wcwidth.py.

generated_cpp_wcwidth.h was regenerated using Unicode 13.0.0 data files. No
material changes to the parsing scripts (either GCC- or glibc-sourced) were
necessary; glibc's utf8_gen.py was tweaked slightly by glibc and matched here.
