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.

contrib/
* unicode/README: Update glibc git commit hash, replace
Unicode 15 or 15.1 versions with 16.
* unicode/gen_libstdcxx_unicode_data.py: Use 160000 instead of
150100 in _GLIBCXX_GET_UNICODE_DATA test.
* unicode/from_glibc/utf8_gen.py: Updated from glibc
064c708c78cc2a6b5802dce73108fc0c1c6bfc80 commit.
* unicode/DerivedCoreProperties.txt: Updated from Unicode 16.0.
* unicode/emoji-data.txt: Likewise.
* unicode/PropList.txt: Likewise.
* unicode/GraphemeBreakProperty.txt: Likewise.
* unicode/DerivedNormalizationProps.txt: Likewise.
* unicode/NameAliases.txt: Likewise.
* unicode/UnicodeData.txt: Likewise.
* unicode/EastAsianWidth.txt: Likewise.
gcc/testsuite/
* c-c++-common/cpp/named-universal-char-escape-1.c: Add tests
for some Unicode 16.0 characters, both normal and generated.
libcpp/
* makeucnid.cc (write_copyright): Update Unicode Copyright years.
* makeuname2c.cc (generated_ranges): Adjust Unicode version from 15.1
to 16.0. Add EGYPTIAN HIEROGLYPH- generated range, adjust indexes in
following entries.
(write_copyright): Update Unicode Copyright years.
* generated_cpp_wcwidth.h: Regenerated.
* ucnid.h: Regenerated.
* uname2c.h: Regenerated.
libstdc++-v3/
* include/bits/unicode.h (std::__unicode::__v15_1_0): Rename inline
namespace to ...
(std::__unicode::__v16_0_0): ... this.
(_GLIBCXX_GET_UNICODE_DATA): Change from 150100 to 160000.
* include/bits/unicode-data.h: Regenerated.
* testsuite/ext/unicode/properties.cc: Check for _Gcb_SpacingMark
on U+11F03 rather than U+1D16D as the latter lost SpacingMark property
in Unicode 16.0.
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.

contrib/
* unicode/README: Adjust glibc git commit hash, number of Unicode
data files to be updated and latest Unicode version.
* unicode/from_glibc/utf8_gen.py: Update from glibc.
* unicode/UnicodeData.txt: Update from Unicode 15.1.
* unicode/EastAsianWidth.txt: Likewise.
* unicode/DerivedNormalizationProps.txt: Likewise.
* unicode/NameAliases.txt: Likewise.
* unicode/DerivedCoreProperties.txt: Likewise.
* unicode/PropList.txt: Likewise.
libcpp/
* makeucnid.cc (write_copyright): Update copyright year.
* makeuname2c.cc (write_copyright): Likewise.
(struct generated): Update latest Unicode version.
(generated_ranges): Add 2ebf0-2ee5d CJK UNIFIED IDEOGRAPH
range which was forgotten to be added to 4-8 table, but
clearly is expected to be there from the 15.1 additions.
* ucnid.h: Regenerated.
* uname2c.h: Regenerated.
* generated_cpp_wcwidth.h: Regenerated.
I've noticed we have instructions on how to update from newer Unicode
standard, but it didn't mention uname2c.h regeneration.
The following patch mentions that, also mentions that the Copyright years
of Unicode should be updated and adds a copy of NameAliases.txt which
is used for uname2c.h generation.

* unicode/README: Update to mention also makeuname2c.
* unicode/NameAliases.txt: New file.
