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.

Existing text output in GCC has to be implemented by writing
sequentially to a pretty_printer instance. This makes it
hard to implement some kinds of diagnostic output (see e.g.
diagnostic-show-locus.cc).
This patch adds more flexible ways of creating text output:
- a canvas class, which can be "painted" to via random-access (rather
that sequentially)
- a table class for 2D grid layout, supporting items that span
multiple rows/columns
- a widget class for organizing diagrams hierarchically.
The patch also expands GCC's diagnostics subsystem so that diagnostics
can have "text art" diagrams - think ASCII art, but potentially
including some Unicode characters, such as box-drawing chars.
The new code is in a new "gcc/text-art" subdirectory and "text_art"
namespace.
The patch adds a new "-fdiagnostics-text-art-charset=VAL" option, with
values:
- "none": don't emit diagrams (added to -fdiagnostics-plain-output)
- "ascii": use pure ASCII in diagrams
- "unicode": allow for conservative use of unicode drawing characters
(such as box-drawing characters).
- "emoji" (the default): as "unicode", but potentially allow for
conservative use of emoji in the output (such as U+26A0 WARNING SIGN).
I made it possible to disable emoji separately from unicode as I believe
there's a generation gap in acceptance of these characters (some older
programmers have a visceral reaction against them, whereas younger
programmers may have no problem with them).
Diagrams are emitted to stderr by default. With SARIF output they are
captured as a location in "relatedLocations", with the diagram as a
code block in Markdown within a "markdown" property of a message.
This patch doesn't add any such diagram usage to GCC, saving that for
followups, apart from adding a plugin to the test suite to exercise the
functionality.

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.

This patch updates ucnid.h from Unicode 13 to Unicode 14. Additionally, the
procedure detailed in contrib/unicode/README, which updates
generated_wcwidth.h, has been expanded with instructions for updating this
file as well, so that both may be done at the same time conveniently. Two
additional Unicode data files which are needed to create ucnid.h are also
added to source control in contrib/unicode.

* unicode/README: Added instructions for updating ucnid.h.

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.

This script may be useful when debugging issues relating to Unicode
encoding (e.g. when investigating source files with bidirectional control
characters).
It dumps a UTF-8 file as a list of numbered lines (mimicking GCC's
diagnostic output format), interleaved with lines per character showing
the Unicode codepoints, the UTF-8 encoding bytes, the name of the
character, and, where printable, the characters themselves.
The lines are printed in logical order, which may help the reader to grok
the relationship between visual and logical ordering in bi-di files.

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.
